Balinese

The Balinese is a breed of oriental cat with long hair and Siamese-style markings, or points. They resemble a Siamese with a medium-length silky coat and a plumed tail, but not nearly as fluffy as a Himalayan, and they require much less grooming. Balinese are extremely intelligent cats, although less talkative than their Siamese ancestors.

Balinese

Balinese – So named after the graceful Balinese dancers.

The Balinese was originally registered as a ‘longhaired Siamese’, and examples were known from the early 1920s. The occasional long-haired kittens in a Siamese litter were seen as an oddity, and sold as household pets rather than as show cats. This changed in the mid-1950s, when two breeders, Mrs. Marion Dorsey of Rai-Mar Cattery in California and Mrs. Helen Smith of MerryMews Cattery in New York, decided that they would commence a breeding program for the longhaired cats. Helen Smith named the cats ‘Balinese’ because she felt they showed the grace and beauty of Balinese dancers, and because ‘longhaired Siamese’ seemed a rather clunky name for such graceful felines. The breed became quite popular after this, and a number of breeders began working on ‘perfecting’ the Balinese appearance. This led eventually to the development of two entirely separate ‘strands’ of Balinese cat – some owners prefer a traditional or ‘apple-headed’ Balinese, while breeders and judges tend to prefer a more contemporary appearance.

Like the Siamese, there are now two different varieties of Balinese being bred and shown – ‘traditional’ Balinese and ‘contemporary’ Balinese. The traditional Balinese cat has a coat approximately two inches long over its entire body and it is a sturdy and robust cat with a semi-rounded muzzle and ears. The traditional Balinese closely resembles a Ragdoll cat although they do not share any of the same genes or breeding other than having a partially Siamese ancestry. A ‘contemporary’ Balinese has a much shorter coat and is virtually identical to a standard show Siamese except for its tail, which is a graceful silky plume.

In most associations, the Balinese is accepted in a full range of colors, including the four traditional Siamese point colors of seal, blue, chocolate, and lilac, as well as less traditional colors such as red and cream, and patterns such as lynx (tabby) point and tortie point. However, in CFA, the Balinese is only accepted in the four traditional Siamese colors; all other colors and patterns are considered Javanese (cat).

Moggy Facts

The Cat (Felis silvestris catus), also known as the Domestic Cat or House Cat to distinguish it from other felines, is a small carnivorous species of mammal that is often valued by humans for its companionship and its ability to hunt vermin. It has been associated with humans for at least 9,500 years, possibly much longer. A skilled predator, the cat is known to hunt over 1,000 species for food. It is intelligent and can be trained to obey simple commands. Individual cats have also been known to learn to manipulate simple mechanisms. Cats use a variety of vocalizations and types of body language for communication, including mewing (“meow” or “miaow”), purring, hissing, growling, squeaking, chirping, clicking, and grunting.

A study by the National Cat Institute published in the journal Science says that all house cats are descended from a group of self-domesticating desert wildcats Felis silvestris lybica circa 10,000 years ago, in the Near East. All wildcat subspecies can interbreed, but domestic cats are all genetically contained within Felis silvestris lybica.

Build

Cats typically weigh between 2.5 and 7 kg (5.5 to 16 pounds); however, some breeds, such as the Maine Coon, can exceed 11.3 kg (25 pounds). Some have been known to reach up to 23 kg (50 pounds) due to overfeeding. Conversely, very small cats (less than 1.8 kg / 4.0 lb)have been reported.

Cats also possess rather loose skin; this allows them to turn and confront a predator or another cat in a fight, even when it has a grip on them. This is also an advantage for veterinary purposes, as it simplifies injections. In fact, the life of cats with kidney failure can sometimes be extended for years by the regular injection of large volumes of fluid subcutaneously, which serves as an alternative to dialysis.

The particularly loose skin at the back of the neck is known as the scruff, and is the area by which a mother cat grips her kittens to carry them. As a result, cats tend to become quiet and passive when gripped there. This tendency often extends into adulthood, and can be useful when attempting to treat or move an uncooperative cat. However, since an adult cat is heavier than a kitten, a pet cat should never be carried by the scruff, but should instead have their weight supported at the rump and hind legs, and at the chest and front paws. Often (much like a small child) a cat will lie with its head and front paws over a person’s shoulder, and its back legs and rump supported under the person’s arm.

Cats have 7 cervical vertebrae like almost all mammals, 13 thoracic vertebrae (humans have 12), 7 lumbar vertebrae (humans have 5), 3 sacral vertebrae like most mammals (humans have 5 because of their bipedal posture), and, except for Manx cats, 22 or 23 caudal vertebrae (humans have 3 to 5, fused into an internal coccyx). The extra lumbar and thoracic vertebrae account for the cat’s enhanced spinal mobility and flexibility, compared with humans. The caudal vertebrae form the tail, used by the cat as a counterbalance to the body during quick movements. Cats also do not possess a clavicle, which allows them to pass their body through any space into which they can fit their head.

Cats have highly specialized teeth and a digestive tract suitable for the digestion of meat. The premolar and first molar together compose the carnassial pair on each side of the mouth, which efficiently functions to shear meat like a pair of scissors. While this is present in dogs, it is highly developed in felines. The cat’s tongue has sharp spines, or papillae, useful for retaining and ripping flesh from a carcass. These papillae are small backward-facing hooks that contain keratin which also assist in their grooming.

Ears

Thirty-two individual muscles in the ear allow for a manner of directional hearing: the cat can move each ear independently of the other. Because of this mobility, a cat can move its body in one direction and point its ears in another direction. Most cats have straight ears pointing upward. Unlike dogs, flap-eared breeds are extremely rare. (Scottish Folds are one such exceptional genetic mutation.) When angry or frightened, a cat will lay back its ears, to accompany the growling or hissing sounds it makes. Cats also turn their ears back when they are playing, or to listen to a sound coming from behind them. The angle of a cat’s ears is an important clue to their mood.

Legs

Cats, like dogs, are digitigrades: they walk directly on their toes, the bones of their feet making up the lower part of the visible leg. Cats are capable of walking very precisely, because like all felines they directly register; that is, they place each hind paw (almost) directly in the print of the corresponding forepaw, minimizing noise and visible tracks. This also provides sure footing for their hind paws when they navigate rough terrain.

Unlike dogs and most mammals, cats walk by moving both legs on one side and then both legs on the other. Most mammals move legs on alternate sides in sequence. Cats share this unusual gait with camels, giraffes, some horses (‘pacers’), and a select few other mammals. There is no known connection between these animals which might explain this.

Like all members of family Felidae except the cheetah, cats have retractable claws. In their normal, relaxed position the claws are sheathed with the skin and fur around the toe pads. This keeps the claws sharp by preventing wear from contact with the ground and allows the silent stalking of prey. The claws on the forefeet are typically sharper than those on the hind feet. Cats can extend their claws voluntarily on one or more paws at will. They may extend their claws in hunting or self-defense, climbing, “kneading”, or for extra traction on soft surfaces (bedspreads, thick rugs, etc.). It is also possible to make a cooperative cat extend its claws by carefully pressing both the top and bottom of the paw. The curved claws may become entangled in carpet or thick fabric, which may cause injury if the cat is unable to free itself.

Most cats have five claws on their front paws, and four or five on their rear paws. Because of an ancient mutation, however, domestic cats are prone to polydactyly, and may have six or seven toes. The fifth front claw (the dewclaw) is in a more proximal position than those of the other claws. More proximally, there is a protrusion which appears to be a sixth “finger”. This special feature of the front paws, on the inside of the wrists, is the carpal pad, also found on the paws of big cats and dogs. It has no function in normal walking, but is thought to be an anti-skidding device used while jumping.

Senses

Cat senses are attuned for hunting. Cats have highly advanced hearing, eyesight, taste, and touch receptors, making the cat extremely sensitive among mammals. Cats’ night vision is superior to humans although their vision in daylight is inferior. Humans and cats have a similar range of hearing on the low end of the scale, but cats can hear much higher-pitched sounds, up to 64 kHz, which is 1.6 octaves above the range of a human, and even one octave above the range of a dog. A domestic cat’s sense of smell is about fourteen times as strong as a human’s. To aid with navigation and sensation, cats have dozens of movable vibrissae (whiskers) over their body, especially their face. Due to a mutation in an early cat ancestor, one of two genes necessary to taste sweetness has been lost by the cat family.

Metabolism

Cats conserve energy by sleeping more than most animals, especially as they grow older. Daily durations of sleep vary, usually 12 to 16 hours, with 13 to14 being the average. Some cats can sleep as much as 20 hours in a 24-hour period. The term cat nap refers to the cat’s ability to fall asleep (lightly) for a brief period and has entered the English lexicon – someone who nods off for a few minutes is said to be “taking a cat nap”.

Due to their crepuscular nature, cats are often known to enter a period of increased activity and playfulness during the evening and early morning, dubbed the “evening crazies”, “night crazies”, “elevenses” or “mad half-hour” by some.

The temperament of a cat can vary depending on the breed and socialization. Cats with “oriental” body types tend to be thinner and more active, while cats that have a “cobby” body type tend to be heavier and less active.

The normal body temperature of a cat is between 38 and 39 deg C (101 and 102.2 deg F). A cat is considered febrile (hyperthermic) if it has a temperature of 39.5 deg C (103 deg F) or greater, or hypothermic if less than 37.5 degC (100 degF). For comparison, humans have a normal temperature of approximately 36.8 deg C (98.6 deg F). A domestic cat’s normal heart rate ranges from 140 to 220 beats per minute, and is largely dependent on how excited the cat is. For a cat at rest, the average heart rate should be between 150 and 180 bpm, about twice that of a human.

Social Behavior

Many people characterize cats as ‘solitary’ animals. Cats are highly social; a primary difference in social behavior between cats and dogs (to which they are often compared) is that cats do not have a social survival strategy, or a ‘pack mentality’; however this only means that cats take care of their basic needs on their own (e.g., finding food, and defending themselves). This is not the same state as being asocial. One example of how domestic cats are ‘naturally’ meant to behave is to observe feral domestic cats, which often live in colonies, but in which each individual basically looks after itself.

Living with humans is a symbiotic social adaptation which has developed over thousands of years. The sort of social relationship cats have with their human keepers is hard to map onto more generalized wild cat behavior, but it is certain that the cat thinks of the human differently than it does other cats (i.e., it does not think of itself as human, nor that the human is a cat). This can be seen in the difference in body and vocal language it uses with the human, when compared to how it communicates with other cats in the household, for example. Some have suggested that, psychologically, the human keeper of a cat is a sort of surrogate for the cat’s mother, and that adult domestic cats live forever in a kind of suspended kitten hood.

With proper training and reinforcement of social behavior, poorly socialized cats can become more social over time. Older cats have also been reported to sometimes develop aggressiveness towards kittens, which may include biting and scratching; this type of behavior is known as Feline Asocial Aggression.

Fondness for heights

Most breeds of cat have a noted fondness for settling in high places, or perching. Animal behaviorists have posited a number of explanations, the most common being that height gives the cat a better observation point, allowing it to survey its “territory” and become aware of activities of people and other pets in the area. In the wild, a higher place may serve as a concealed site from which to hunt; domestic cats are known to strike prey by pouncing from such a perch as a tree branch, as does a leopard. Height, therefore, can also give cats a sense of security and prestige.

During a fall from a high place, a cat can reflexively twist its body and right itself using its acute sense of balance and flexibility. This is known as the cat’s “righting reflex.” It always rights itself in the same way, provided it has the time to do so, during a fall. The height required for this to occur in most cats (safely) is around 3 feet (90 cm). To achieve this, cats probably relax their ventral muscles, “flattening” their bodies to some extent and creating more resistance to air. Cats without a tail also have this ability, since a cat mostly moves its hindlegs and relies on conservation of angular momentum to set up for landing, and the tail is in fact little used for this feat.

However, cats’ fondness for high spaces can dangerously test the righting reflex. The American Society for the Prevention of Cruelty to Animals warns owners to safeguard the more dangerous perches in their homes, to avoid “high-rise syndrome,” where an overconfident cat falls from an extreme height.

Play

Domestic cats, especially young kittens, are known for their love of play. This behaviour mimics hunting and is important in helping kittens learn to stalk, capture and kill prey. Many cats cannot resist a dangling piece of string, or a piece of rope drawn randomly and enticingly across the floor. This well known love of string is often depicted in cartoons and photographs, which show kittens or cats playing with balls of yarn. It is probably related to hunting instincts, including the common practice of kittens hunting their mother’s and each other’s tails.
If string is ingested, however, it can become caught in the cat’s stomach or intestines, causing illness.

Due to possible complications caused by ingesting a string, string play is sometimes replaced with a laser pointer’s dot, which some cats will chase. While caution is called for, there are no documented cases of feline eye damage from a laser pointer, and the combination of precision needed and low energy involved make it a remote risk. A down side of the lazer toy is the frustration caused to the cat who has nothing tangigle to claw!

Ecology

Feeding

Cats are highly specialized for hunting and have evolved to survive on a meat-based diet. Since they have a greatly reduced need to digest plants, their digestive tract has evolved to be shorter, too short for effective digestion of plants but less of a weight penalty for the rapid movement required for hunting. Hunting has likewise become central to their behavior patterns, even to their predilection for short bursts of intense exercise punctuating long periods of rest.

Much like the big cats, domestic cats are very effective predators. They ambush and immobilize vertebrate prey using tactics similar to those of leopards and tigers by pouncing; then they deliver a lethal neck bite with their long canine teeth that severs the victim’s spinal cord, causes fatal bleeding by puncturing the carotid artery or the jugular vein, or asphyxiates it by crushing its trachea. The domestic cat hunts and eats over a thousand species, many of them invertebrates, especially insects, whilst many big cats will eat fewer than a hundred different species. Although, theoretically, big cats can kill most of these species as well, they often do not due to the relatively low nutritional content that smaller animals provide for the effort. An exception is the leopard, which commonly hunts rabbits and many other smaller animals.

Even well-fed domestic cats may hunt and kill birds, mice, rats, scorpions, cockroaches, grasshoppers, and other small animals in their environment. They often present such trophies to their owner. The motivation is not entirely clear, but friendly bonding behaviors are often associated with such an action. It is probable that cats in this situation expect to be praised for their symbolic contribution to the group. Some theories suggest that cats see their owners gone for long times of the day and assume they are out hunting, as they always have plenty of food available.

Ethologist Paul Leyhausen, in an extensive study of social and predatory behavior in domestic cats (documented in his book Cat Behavior), proposed a mechanism which explains this presenting behavior. In simple terms, cats adopt humans into their social group, and share excess kill with others in the group according to the local pecking order, in which humans place at or near the top. Another possibility is that presenting the kill might be a relic of a kitten feline behavior of demonstrating for its mother’s approval that it has developed the necessary skill for hunting.

Due to their hunting behavior, in many countries feral cats are considered pests. Domestic cats are occasionally also required to have contained cat runs or to be kept inside entirely, as they can be hazardous to locally endangered bird species. For instance, various municipalities in Australia have enacted such legislation. In some localities, owners fit their cat with a bell in order to warn prey of its approach, however the cat may figure out how and when the bell works and learn to move more carefully to avoid ringing it.

Domesticated cats eat fairly little vegetable matter. It is quite common, however, for cats to occasionally supplement their carnivorous diets with small amounts of grass or other plant matter. Cats munch on grass, leaves, shrubs and houseplants to facilitate regurgitation of whatever may be upsetting their digestion; or perhaps to introduce fibre or trace minerals to the diet. Whereas bears and dogs commonly supplement their diet of meat with fruits, berries, roots, and honey when they can get them, cats prefer to mostly feed on meat. All felines, including the big cats, have a genetic anomaly that prevents them from tasting sweetness, which very likely is related to their meat-dominated eating habits, and almost certainly related to their aversion to fruits and berries. However, many domesticated cats are known to like vegetables. The majority of brand-name cat foods are primarily meat based, but often contain large amounts of corn or rice, supplemented with meat byproducts and minerals and vitamins.

Cats are obligate carnivores, and cannot live on an unsupplemented vegetarian diet because they cannot synthesize several required nutrients which are absent or rare in plant food. This applies mainly to taurine, vitamin A (cats cannot convert the pro-vitamin A that is abundant in plants to vitamin A proper) and to certain fatty acids. The absence of taurine causes the cat’s retina to slowly degenerate, causing eye problems and (eventually) irreversible blindness, a condition called macular degeneration. Cow’s milk is a poor source of taurine and adult cats are generally lactose intolerant. Lactose-free milk is perfectly safe, but still not a substitute for meat.

Some houseplants are harmful to cats. The leaves of the Easter Lily can cause permanent and life-threatening kidney damage to cats. Philodendron are also poisonous to cats. Cat Fancy has a full list of plants harmful to cats.

Some cats have a fondness for catnip, which is sensed by their olfactory systems. While they generally do not consume it, they will often roll in it, paw at it, and occasionally chew on it. The effect is usually relatively short, lasting for only a few minutes. After two hours or less, susceptible cats gain interest again. Several other species of plants (such as mint) cause this effect, to a lesser degree.

Cats can be fussy eaters, possibly due to the mutation which caused their ancestor to lose the ability to taste sugars. Unlike most mammals, cats can voluntarily starve themselves indefinitely despite being presented with palatable food, even a food which they had previously readily consumed. This can happen when the vomeronasal or Jacobson’s organ becomes accustomed to a specific food, or if the cats are spoiled by their owners, in which case the cat will reject any food that does not fit the pattern it is expecting. It is also known for cats to merely become bored with their given food and decide to stop eating until they are tempted into eating again. Although it is extremely rare for a cat to deliberately starve itself to the point of injury, the sudden loss of weight can cause a fatal condition called hepatic lipidosis, a liver dysfunction which causes pathological loss of appetite and reinforces the starvation, which can lead to death within as little as 48 hours.

Additionally, cats have been known to develop a fondness for prepared human foods, normally preparations which are rich in proteins or fats. However, a diet consisting only of human food (even if high quality meat) is unlikely to contain the balanced nutrition required by the cat. Cats normally are good self-regulators of diet; however, unlimited access to food, or excessive human-food ‘treats’, will often lead to the cat becoming obese, particularly if it is older or more sedentary. This may lead to several health complications, such as diabetes, especially in neutered males. Such health conditions can be prevented through diet and exercise (playing), especially for cats living exclusively indoors.

Cats can also develop pica. Pica is a condition in which animals chew or eat unusual things such as fabric, plastic or wool. In cats, this is mostly harmless as they do not digest most of it, but can be fatal or require surgical removal if a large amount of foreign material is ingested (for example, an entire sock). It tends to occur more often in Siamese, Burmese, and breeds with these in their ancestry.

Toxic sensitivity

The liver of a cat is less effective at detoxification than those of other animals, including humans and dogs; therefore exposure to many common substances considered safe for households may be dangerous to them. In general, the cat’s environment should be examined for the presence of such toxins and the problem corrected or alleviated as much as possible; in addition, where sudden or prolonged serious illness without obvious cause is observed, the possibility of toxicity must be considered, and the veterinarian informed of any such substances to which the cat may have had access.

For instance, the common painkiller paracetamol or acetaminophen, sold under brand names such as Tylenol and Panadol, is extremely toxic to cats; because they naturally lack enzymes needed to digest it, even minute portions of doses safe for humans can be fatal and any suspected ingestion warrants immediate veterinary attention. Even aspirin, which is sometimes used to treat arthritis in cats, is much more toxic to them than to humans and must be administered cautiously. Similarly, application of minoxidil (Rogaine) to the skin of cats, either accidental or by well-meaning owners attempting to counter loss of fur, has sometimes proved fatal.

In addition to such obvious dangers as insecticides and weed killers, other common household substances that should be used with caution in areas where cats may be exposed to them include mothballs and other naphthalene products, as well as phenol based products often used for cleaning and disinfecting near cats’ feeding areas or litter boxes, such as Pine-Sol, Dettol (Lysol), hexachlorophene, etc. which, although they are widely used without problem, have been sometimes seen to be fatal. Antifreeze is particularly appealing to cats, and as little as a teaspoonful can be fatal.

Many human foods are somewhat toxic to cats; theobromine in chocolate can cause theobromine poisoning, for instance, although few cats will eat chocolate. Toxicity in cats ingesting relatively large amounts of onions or garlic has also been reported. Even such seemingly safe items as cat food packaged in pull tab tin cans have been statistically linked to hyperthyroidism; although the connection is far from proved, suspicion has fallen on the use of bisphenol A, another phenol based product as discussed above, to seal such cans.

Many houseplants are at least somewhat toxic to many species, cats included and the consumption of such plants by cats is to be avoided.

Habitat

The Wildcat, ancestor of the domestic cat, is believed to have evolved in a desert climate, as evident in the behavior common to both the domestic and wild forms. Wild cats are native to all continents other than Australia and Antarctica, although feral cats have become apex predators in the Australian Outback where they are menaces to wildlife. Their feces are usually dry, and cats prefer to bury them in sandy places. Urine is highly concentrated, which allows the cat to retain as much fluid as possible. They are able to remain motionless for long periods, especially when observing prey and preparing to pounce. In North Africa there are still small wildcats that are probably related closely to the ancestors of today’s domesticated breeds.

Cats enjoy heat and solar exposure, often sleeping in a sunny area during the heat of the day. Cats prefer warmer temperatures than humans do. People start to feel uncomfortable when their skin’s temperature gets higher than about 44.5 Deg C (112 Deg F), but cats do not start to show signs of discomfort until their skin reaches about 52 Deg C (126 Deg F).

Being closely related to desert animals, cats can easily withstand the heat and cold of a temperate climate, but not for extended periods. Although certain breeds such as the Norwegian Forest Cat and Maine Coon have developed heavier coats of fur than other cats, they have little resistance against moist cold (eg, fog, rain and snow) and struggle to maintain their 39 Deg C (102 Deg F) body temperature when wet.

Most cats dislike immersion in water; one major exception is the Turkish Van breed which has an unusual fondness for water. Abyssinians are also reported to be more tolerant of water than most cats.

Life history

Reproduction

Cats are seasonally polyestrous, which means they may have many periods of heat over the course of a year. A heat period lasts about 4 to 7 days if the female is bred; if she is not, the heat period lasts longer.

Multiple males will be attracted to a female in heat. The males will fight over her, and the victor wins the right to mate. At first, the female will reject the male. But eventually, the female will allow the male to mate. The female will give a loud yowl as the male pulls out of her. After mating, the female will give herself a thorough wash. If a male attempts to breed with her at this point, the female will attack him. Once the female is done grooming, the cycle will repeat.

The male cat’s penis has spines which point backwards. Upon withdrawal of the penis, the spines rake the walls of the female’s vagina, which may cause ovulation. Because this does not always occur, females are rarely impregnated by the first male with which they mate. Furthermore, cats are superfecund; that is, a female may mate with more than one male when she is in heat, meaning different kittens in a litter may have different fathers.

The gestation period for cats is approximately 63 to 65 days. The size of a litter averages three to five kittens, with the first litter usually smaller than subsequent litters. Kittens are weaned at between six and seven weeks, and cats normally reach sexual maturity at 4 to 10 months (females) and to 5 to 7 months (males).

Cats are ready to go to new homes at about 12 weeks old (the recommended minimum age by Federation Internationale Feline), or when they are ready to leave their mother. Cats can be surgically sterilized (spayed or neutered) as early as 6 to 8 weeks to limit unwanted reproduction. This surgery also prevents undesirable sex-related behavior, such as territory marking (spraying urine) in males and yowling (calling) in females. If an animal is neutered after such behavior has been learned, however, it may persist.
Blue-eyed cats with white fur have a higher incidence of genetic deafness.

Genetics

The domestic cat and its closest wild ancestor both possess 38 chromosomes, in which over 200 heritable genetic defects have been identified, many homologous to human inborn errors. Specific metabolic defects have been identified underlying many of these feline diseases. There are several genes responsible for the hair color identified. The combination of them gives different phenotypes.

Features like hair length, lack of tail or presence of a very short tail (bobtail cat) are also determined by single alleles and modified by polygenes.

The Cat Genome Project, sponsored by the Laboratory of Genomic Diversity at the U.S. National Cancer Institute Frederick Cancer Research and Development Center in Frederick, Maryland, focuses on the development of the cat as an animal model for human hereditary disease, infectious disease, genome evolution, comparative research initiatives within the family Felidae, and forensic potential.

It is a common misconception that all white cats with blue eyes are deaf, leading to some people rejecting blue eyed white cats as pets. This is not true, as there are many blue eyed cats with perfect hearing. However, white cats with blue eyes do have slightly higher incidences of genetic deafness than white cats of other eye colours.

Etymology and Taxonomic history

Scientific classification

The domestic cat was named Felis catus by Carolus Linnaeus in his Systema Naturae of 1758. Johann Christian Daniel von Schreber named the Wildcat Felis silvestris in 1775. However, in opinion 2027 (published in Volume 60, Part 1 of the Bulletin of Zoological Nomenclature, March 31, 2003) the International Commission on Zoological Nomenclature “conserved the usage of 17 specific names based on wild species, which are predated by or contemporary with those based on domestic forms”, thus confirming F. silvestris for the Wildcat and F. silvestris catus for its domesticated cousin.

Johann Christian Polycarp Erxleben (Professor of physics and veterinary medicine at the University of Göttingen) wrote “Anfangsgründe der Naturlehre” in 1777) and in doing so named the domestic cat Felis domesticus. This name, and its variants Felis catus domesticus and Felis silvestris domesticus, are often seen, but they are not valid scientific names under the rules of the International Code of Zoological Nomenclature.

Nomenclature

A group of cats is referred to as a clowder, a male cat is called a tom (or a gib, if neutered), and a female is called a queen. The male progenitor of a cat, especially a pedigreed cat, is its sire, and its female progenitor is its dam. An immature cat is called a kitten (which is also an alternative name for young rats, rabbits, hedgehogs, beavers, squirrels and skunks). In medieval Britain, the word kitten was interchangeable with the word catling. A cat whose ancestry is formally registered is called a pedigreed cat, purebred cat, or a show cat (although not all show cats are pedigreed or purebred).

In strict terms, a purebred cat is one whose ancestry contains only individuals of the same breed. A pedigreed cat is one whose ancestry is recorded, but may have ancestors of different breeds (almost exclusively new breeds; cat registries are very strict about which breeds can be mated together). Cats of unrecorded mixed ancestry are referred to as domestic longhairs and domestic shorthairs or commonly as random-bred, moggies, mongrels, mutt-cats or alley cats. The ratio of pedigree/purebred cats to random-bred cats varies from country to country. However, generally speaking, purebreds are less than ten percent of the total feline population.

The word cat derives from Old English catt, which belongs to a group of related words in European languages, including Welsh cath, Spanish gato, Basque katu, Byzantine Greek κάττα, Old Irish cat, German Katze, and Old Church Slavonic kotka. The ultimate source of all these terms is unknown, although it may be linked to the ancient Nubian kadis and the Berber kadiska (both meaning “cat”).

The term puss (as in pussycat) may come from Dutch (from “poes” (or the diminutive “poesje”), which primarily denotes a female cat but is also used as an endearing term for any cat) or from other Germanic languages.

Finally, the word Moggy was first recorded in 1911, and was possibly derived from maggie, margie or mog, all short forms of the female name Margaret. It is thought this was first used to describe an ungainly lumbering cow, and it may even have been a minor rural English name for any cow; since ‘moggy’ was used in several 1800’s English dialects as an ‘affectionate name’ for a cow. As rural people flocked to the cities during the latter part of the Industrial Revolution, it seems likely that the cow moggy became maggie, applied as a term of abuse for a dishevelled woman or ‘lady of the night’.

The origin is obviously confused, but as the early 20th century streets of London became filled with very many unhealthy looking stray cats, it would have been natural to apply the term moggy to describe these unfortunate creatures. In parts of Lancashire, England the word ‘moggy’ means mouse not cat. A cat was known as ‘the moggy catcher’. It has been suggested that this could be the etymology of the word moggy meaning ‘cat’ – over time the catcher part was dropped from ‘the moggy catcher’ and so moggy now means both ‘mouse’ and ‘cat’ source:https://www.answers.com.

Importance to humans

Because of their small size, domestic cats pose almost no danger to humans, the main hazard is the possibility of infection (e.g., cat scratch disease, or, rarely, rabies) from a cat bite or scratch. Cats can also potentially inflict severe scratches or puncture an eye, though this is quite rare. Dogs have been known to be blinded by cats in fights in which the cat specifically targeted the eyes of the larger animal with some accuracy.

Cats can be destructive to ecosystems in which they are not native and whose species have not had time to adapt to their introduction. In some cases, cats have contributed to or caused extinctions for example in the case of the Stephens Island Wren.

Cats as pets

In captivity, indoor cats typically live 14 to 20 years, though the oldest-known cat lived to age 36. Domestic cats tend to live longer if they are not permitted to go outdoors (reducing the risk of injury from fights or accidents and exposure to diseases) and if they are spayed or neutered. Some such benefits are: neutered male cats cannot develop testicular cancer, spayed female cats cannot develop ovarian cancer, and both have a reduced risk of mammary cancer.

Hygiene

Cats are known for their fastidious cleanliness. They groom themselves by licking their fur, employing their hooked papillae and saliva. Their saliva is a powerful cleaning agent, but it can provoke allergic reactions in humans. Some people who are allergic to cats, typically manifested by hay fever, asthma or a skin rash, quickly acclimate themselves to a particular animal and live comfortably in the same house with it, while retaining an allergy to cats in general. Many cats also enjoy grooming humans or other cats. Sometimes the act of grooming another cat is initiated as an assertion of superior position in the pecking order of a group (dominance grooming). Some cats occasionally regurgitate hair balls of fur that have collected in their stomachs as a result of their grooming. Longhair cats are more prone to this than shorthairs’. Hairballs can be prevented with certain cat foods and remedies that ease elimination of the hair and regular grooming of the coat with a comb or stiff brush. Cats expend nearly as much fluid grooming as they do urinating.

Indoor cats are usually provided with a litter box containing litter, typically bentonite, but sometimes other absorbent material such as shredded paper or wood chips, or sometimes sand or similar material. This arrangement serves the same purpose as a toilet for humans. It should be cleaned daily and changed often, depending on the number of cats in a household and the type of litter; if it is not kept clean, a cat may be fastidious enough to find other locations in the house for urination or defecation. This may also happen for other reasons; for instance, if a cat becomes constipated and defecation is uncomfortable, it may associate the discomfort with the litter box and avoid it in favor of another location. A litterbox is recommended for indoor-outdoor cats as well. Daily attention to the litter box also serves as a monitor of the cat’s health. Numerous variations on litter and litter box design exist, including some which automatically sift the litter after each use. Bentonite or clumping litter is a variation which absorbs urine into clumps which can be sifted out along with feces, and thus stays cleaner longer with regular sifting, but has sometimes been reported to cause health problems in some cats.

Litterboxes may pose a risk of toxoplasmosis transmission to susceptible pregnant women and immuno-compromised individuals. Most indoor-only cats would not normally be exposed to the disease and are not usually carriers. Transmission risk may be reduced by daily litterbox cleaning by someone other than the susceptible individual.

Some cats can be toilet trained, eliminating the litterbox and its attendant expense, unpleasant odor, and the need to use landfill space for disposal. Training may involve two or three weeks of incremental moves, such as moving and elevating the litterbox until it is near the toilet. For a short time, an adapter, such as a bowl or small box, may be used to suspend the litter above the toilet bowl but under the toilet seat. Numerous kits and other aids are marketed to help toilet-train cats. When training is complete, the cat uses the toilet by perching over the bowl. Although most cats have a good sense of balance, an accidental fall into the toilet bowl, which may traumatize the cat to the point of its avoidance of the toilet, may lead to urinating and defecating in undesirable areas.

Scratching

Cats are naturally driven to periodically hook their front claws into suitable surfaces and pull backwards, in order to clean the claws and remove the worn outer sheath as well as exercise and stretch their muscles. This scratching behavior seems enjoyable to the cat, and even declawed cats will go through elaborate scratching routines with every evidence of great satisfaction, despite the total lack of results. Indoor cats benefit from being provided with a scratching post so that they are less likely to use carpet or furniture which they can easily ruin. Commercial scratching posts typically are covered in carpeting or upholstery, but some authorities advise against this practice, as not making it clear to the cat which surfaces are permissible and which are not; they suggest using a plain wooden surface, or reversing the carpeting on the posts so that the rougher texture of the carpet backing is a more attractive alternative to the cat than the floor covering. Scratching posts made of sisal rope or corrugated cardboard are also commonly found. Some indoor cats, however, especially those that were taken as kittens from feral colonies, may not understand the concept of a scratching post, and as a result will ignore it.

Although scratching can serve cats to keep their claws from growing excessively long, their nails can be trimmed if necessary, with a small nail trimmer designed for humans, a small pair of electrician’s diagonal cutting pliers, or a guillotine type cutter specifically designed for animal nail trimming. Care must always be taken to avoid cutting the quick of the claw, analogous to cutting into the tip of a finger and equally painful and bloody. The position of the quick can be easily seen through the translucent nail of a cat with light colored claws but not in cats with dark colored nails, who therefore require carefully trimming of only small amounts from the nails.

Declawing

Declawing is a major surgery known as onychectomy, performed under anesthesia, which removes the tip of each digit (from the first knuckle out) of the cat’s forepaws (and rarely the hind paws). (please, please don’t do it, just let the creature go back to the cattery if you or your child doesn’t like claws! — Norman… I’ll second that Oscar ).

The primary reason for declawing cats is to prevent them from damaging furniture; in the United States, some landlords may require that tenants’ cats be declawed. Rarely, vicious cats, cats that frequently fight with other pets, or cats that are too efficient at predation of songbirds etc. are declawed. The procedure is illegal in many countries worldwide.

An alternative to declawing is the application of blunt, vinyl nail caps that are affixed to the claws with nontoxic glue, requiring periodic replacement when the cat sheds its claw sheaths (about every four to six weeks). However, the cat will still experience difficulties because the capped nails are not as effective as claws.

Domestication

In 2004, a grave was excavated in Cyprus that contained the skeletons, laid close to one another, of both a human and a cat. The grave is estimated to be 9,500 years old, pushing back the earliest known feline-human association significantly. Like some other domesticated animals, cats live in a mutually benficial arrangement with humans. It is believed that the benefit of removing rats and mice from humans’ food stores outweighed the trouble of extending the protection of a human settlement to a formerly wild animal, almost certainly for humans who had adopted a farming economy. Unlike the dog, which also hunts and kills rodents, the cat does not eat grains, fruits, or vegetables. A cat that is good at hunting rodents is referred to as a mouser.

The simile “like herding cats” refers to the seeming intractability of the ordinary house cat to training in anything, unlike dogs. Despite cohabitation in colonies, cats are lone hunters. It is no coincidence that cats are also “clean” animals; the chemistry of their saliva, expended during their frequent grooming, appears to be a natural deodorant. If so, the function of this cleanliness is to decrease the chance a prey animal will notice the cat’s presence in time. In contrast, dog’s odor is an advantage in hunting, for a dog is a pack hunter; part of the pack stations itself upwind, and its odor drives prey towards the rest of the pack stationed downwind. This requires a cooperative effort, which in turn requires communications skills. No such communications skills are required of a lone hunter. It is likely this is part of the reason interacting with such an animal is problematic; cats in particular are labeled as opaque or inscrutable, if not obtuse, as well as aloof and self-sufficient. However, cats can be very affectionate towards their human companions, especially if they imprint on them at a very young age and are treated with consistent affection.

Human attitudes toward cats vary widely. Some people keep cats for companionship as pets. Others go to great lengths to pamper their cats, sometimes treating them as if they were children. When a cat bonds with its human guardian, the cat may, at times, display behaviors similar to that of a human. Such behavior may include a trip to the litter box before bedtime or snuggling up close to its companion in bed or on the sofa. Other such behavior includes mimicking sounds of the owner or using certain sounds the cat picks up from the human; sounds representing specific needs of the cat, which the owner would recognize, such as a specific tone of meow along with eye contact that may represent “I’m hungry.” The cat may also be capable of learning to communicate with the human using non-spoken language or body language such as rubbing for affection (confirmation), facial expressions and making eye contact with the owner if something needs to be addressed (e.g., finding a bug crawling on the floor for the owner to get rid of). Some owners like to train their cat to perform “tricks” commonly exhibited by dogs such as jumping, though this is rare.

Allergies to cat dander are one of the most common reasons people cite for disliking cats. However, in some instances, humans find the rewards of cat companionship outweigh the discomfort and problems associated with these allergies. Many choose to cope with cat allergies by taking prescription allergy medicine and bathing their cats frequently, since weekly bathing will eliminate about 90% of the cat dander present in the environment.

In urban areas, some people find feral and free-roaming pet cats annoying and intrusive. Unaltered animals can engage in persistent nighttime calling (termed caterwauling) and defecation or “marking” of private property. Indoor confinement of pets and TNR (trap, neuter, return) programs for feral cats can help; some people also use cat deterrents to discourage cats from entering their property.

In rural areas, farms often have dozens of semi-feral cats. Hunting in the barns and the fields, they kill and eat rodents that would otherwise spoil large parts of the grain crop. Many pet cats successfully hunt and kill rabbits, rodents, birds, lizards, frogs, fish, and large insects by instinct, but might not eat their prey. They may even present their kills, dead or maimed, to their humans, perhaps expecting them to praise or reward them, or possibly even to complete the kill and eat the mouse. Others speculate that the behavior is a part of the odd relationship between human and cat, in which the cat is sometimes a ‘kitten’ (playing, being picked up and carried) and sometimes an adult (teaching these very large and peculiar kittens how to hunt by demonstrating what the point of it all is).

The domestic cat is social enough to form colonies, but does not hunt in groups as lions do. Some breeds like bengal, ocicat and manx are known to be very social. While each cat holds a distinct territory (sexually active males having the largest territories, and neutered cats having the smallest), there are “neutral” areas where cats watch and greet one another without territorial conflicts. Outside these neutral areas, territory holders usually aggressively chase away stranger cats, at first by staring, hissing, and growling, and if that does not work, by short but noisy and violent attacks. Fighting cats make themselves appear more impressive and threatening by raising their fur and arching their backs, thus increasing their visual size. Cats also behave this way while playing. Attacks usually comprise powerful slaps to the face and body with the forepaws as well as bites, but serious damage is rare; usually the loser runs away with little more than a few scratches to the face, and perhaps the ears. Cats will also throw themselves to the ground in a defensive posture to rake with their powerful hind legs. Normally, serious negative effects will be limited to possible infections of the scratches and bites; though these have been known to sometimes kill cats if untreated. In addition, such fighting is believed to be the primary route of transmission of feline immunodeficiency virus (FIV). Sexually active males will usually be in many fights during their lives, and often have decidedly battered faces with obvious scars and cuts to the ears and nose. Not only males will fight; females will also fight over territory or to defend their kittens, and even neutered cats will defend their (smaller) territories aggressively.

Domesticated Cat varieties

The list of cat breeds is quite large: most cat registries recognize between 30 and 40 breeds of cats, and several more are in development, with one or more new breeds being recognized each year on average, having distinct features and heritage. The owners and breeders of show cats compete to see whose animal bears the closest resemblance to the “ideal” definition of the breed (see selective breeding). Because of common crossbreeding in populated areas, many cats are simply identified as belonging to the homogeneous breeds of domestic longhair and domestic shorthair, depending on their type of fur. In the United Kingdom and Australia, non-purebred cats are referred in slang as moggies (derived from “Maggie”, short for Margaret, reputed to have been a common name for cows and calves in 18th century England and latter applied to housecats during the Victorian era). In the United States, a non-purebred cat is sometimes referred to in slang as a barn or alley cat, even if it is not a stray. Cats come in a variety of colors and patterns. These are physical properties and should not be confused with a breed of cat. Some original cat breeds that have a distinct phenotype that is the main type occurring naturally as the dominant domestic cat type in their region of origin are sometimes considered as subspecies and also have received names as such in nomenclature, although this is not supported by feline biologists. Some of These cat breeds are:

* F. catus anura – the Manx

* F. catus siamensis – the Siamese

* F. catus cartusenensis – the Chartreux

* F. catus angorensis – the Turkish Angora

Coat patterns

Cat coat genetics can produce a variety of coat patterns. Some of the most common are:

Bicolor, Tuxedo and Van
This pattern varies between the tuxedo cat which is mostly black with a white chest, and possibly markings on the face and paws/legs, all the way to the Van pattern (so named after the Lake Van area in Turkey, which gave rise to the Turkish Van breed), where the only colored parts of the cat are the tail (usually including the base of the tail proper), and the top of the head (often including the ears). There are several other terms for amounts of white between these two extremes, such as harlequin or jellicle cat. Bicolor cats can have as their primary (non-white) color black, red, any dilution thereof and tortoiseshell (see below for definition).

Tabby cat
Striped, with a variety of patterns. The classic “blotched” tabby (or “marbled”) pattern is the most common and consists of butterflies and bullseyes. The “mackerel” or “striped” tabby is a series of vertical stripes down the cat’s side (resembling the fish). This pattern broken into spots is referred to as a “spotted” tabby. Finally, the tabby markings may look like a series of ticks on the fur, thus the “ticked” tabby, which is almost exclusively associated with the Abyssinian breed of cats. The worldwide evolution of the cat means that certain types of tabby are associated with certain countries; for instance, blotched tabbies are quite rare outside NW Europe, where they are the most common type.

Tortoiseshell and Calico
This cat is also known as a Calimanco cat or Clouded Tiger cat, and by the nickname “tortie”. In the cat fancy, a tortoiseshell cat is randomly patched over with red (or its dilute form, cream) and black (or its dilute blue) mottled throughout the coat.

Additionally, the cat may have white spots in its fur, which make it a “tortoiseshell and white” cat or, if there is a significant amount of white in the fur and the red and black colors form a patchwork rather than a mottled aspect, the cat will be called a “calico”. All calicos are tortoiseshell (as they carry both black and red), but not all tortoiseshells are calicos (which requires a significant amount of white in the fur and patching rather than mottling of the colors). The calico is also sometimes called a “tricolor cat”. The Japanese refer to this pattern as mi-ke (meaning “triple fur”), while the Dutch call these cats lapjeskat (meaning “patches cat”). A true tricolor must consist of three colors: a reddish color, dark or light; white; and one other color, typically a brown, black or blue, as described by American breeder Barbara French, writing for the Cat Fanciers community. Both tortoiseshell and calico cats are typically female because the coat pattern is the result of differential X chromosome inactivation in females (which, as with all normal female mammals, have two X chromosomes). Those male tortoiseshells that are created are usually sterile; conversely, cats where the overall color is ginger (orange) are commonly male (roughly in a 3:1 ratio). In a litter sired by a ginger tom, the females will be tortoiseshell or ginger. See “Tortoiseshell and Tricolour Cats” for an extensive genetic explanation for tricolor cats, and detailing the possible combinations of coloring.

Colorpoint
The colorpoint pattern is most commonly associated with Siamese cats, but may also appear in any domestic cat. A colorpoint cat has dark colors on the face, ears, feet, and tail, with a lighter version of the same color on the rest of the body, and possibly some white. The exact name of the colorpoint pattern depends on the actual color, so there are seal points (dark brown), chocolate points (warm lighter brown), blue points (dark gray), lilac points (silvery gray-pink), flame points (orange), and tortie (tortoiseshell mottling) points, among others. This pattern is the result of a temperature sensitive mutation in one of the enzymes in the metabolic pathway from tryptophan to pigment, such as melanin; thus, little or no pigment is produced except in the extremities or “points”, where the skin is slightly cooler. For this reason, colorpoint cats tend to darken with age as bodily temperature drops; also, the fur over a significant injury may sometimes darken or lighten as a result of temperature change.

The tryptophan pathway also produces neurotransmitters, thus mutations in the early parts of that pathway may affect not only pigment, but also neurological development. This results in a higher frequency of cross-eyes among colorpoint cats, as well as the high frequency of deafness in white cats and the high frequency of cross-eyes in white tigers. (This is not related to albinism).

Body types

Cats can also come in several body types, ranging between two extremes (Oriental and Cobby):

Oriental or Slender

Not a specific breed, but any cat with an elongated slender build, almond-shaped eyes, long nose, large ears (the Siamese, Cornish Rex and oriental shorthair breeds are examples of this).

Foreign/Svelte

Cats in this category can be described as long and firm bodied, with the legs in proportion and the tail long and tapered.

The head must be a modified wedge with the ears large and the eyes oval shaped. The Somali is an example of this category.

Semi-foreign

This type of body is a little less slender and less long than the svelte cat body type.

The head is a modified wedge shape with ears not as large. Cats in this category are usually fine or medium boned and the American Curl is a perfect example.

Semi-cobby/Robust

Slightly less compact and usually less round than the cobby body type. These cats can also be described as robust or chunky. The Bombay is an example of this body type.

Cobby or compact

Any cat with a short, muscular, compact build, roundish eyes, short nose, and small ears. Cats in this category have rounded heads and short tails. These cats are normally thick set and have shorter legs. Persian cats and Exotic cats are two prime examples of such a body type.

Bombay

The Bombay is two distinct breeds of cat (please see below). These are muscular yet agile cats with a black coat. The heads of Bombay cats are rounded and wide with a short tapered muzzle. The eyes, which are of golden or copper color, are rounded and set wide, and their ears are broad, slightly rounded and medium sized and, like the eyes, set wide.

Bombay

American Bombay

The Bombay has a coat that is short, satiny and tight to the body. Bombay cats do not require grooming, although petting the cat will keep their coat shiny and will also remove dead hair. A rubber brush can help when the cat sheds larger amounts of fur (uncommon). If the cat is fed a balanced diet, the coat will shine and the cat’s naturally energetic personality will become evident.

Personality

Bombay cats crave human affection like most felines. The Bombay appreciates affection and purrs loudly. Bombay cats are quiet and watchful and prefer living indoors. They can be affected by loud intrusive noises as loud noises make the Bombay nervous. A symptom of this nervousness is that they lose fur from their belly and near their tail. One remedy for this is to simply keep the cat indoors or away from loud noises and make sure they have somewhere to hide. Some convenient locations where a cat can hide are behind chairs, cupboards and almost anywhere that it is difficult for a predator to gain entry, including spaces behind TVs, inside cabinets and underneath small tables.

While Bombay cats will tolerate other breeds of cat, they may tend to dominate other cats. Bombay cats seem to get along well with dogs. Dogs are pack animals and have a pecking order which the Bombay will take advantage of.

Like most cats that have been raised properly, Bombay cats are smart, agile and inquisitive. They will often seek out human interaction. Bombays will investigate packages and will commonly chew through bags and containers to get at food. This can lead to problems if they eat chicken bones which can injure the cat’s throat.

Bombay cats are by nature lap cats. They seek heat and will jump up on their owner’s backs and rest around their neck for comfort and reassurance.These cats are head-bumpers and nose-rubbers, Some can be very “talkative” (meow loudly) and have distinct “voices”. The Bombay will often “fetch”, and takes on other dog-like characteristics. These cats love nothing more than to be held and fussed over. Sensitive, reserved and intelligent, the Bombay is suited to life in a quiet home, where it is affectionate to the whole family. Both males and females are excellent pets.

Bombay cats enjoy being around anyone, but may select someone specific to pay the most attention to. They are wonderful for families with children but may be at first annoyed with a new cat in the house.

Bombay cats are rumoured to have sometimes unusual diets as lap cats. They may actually eat not just sour cream, but baked cookies or beans if the situation arises. Like many other species of domestic cats, they are rather sneaky and creative at the kitchen table.

British Bombay
The British Bombay cat is the name given to black cats of the Asian group. It is a cat of Burmese type with a black coat, toes, nose, and copper to greenish eyes.

American Bombay
The American breed called Bombay was created in 1958 in Louisville, Kentucky, when Nikki Horner of Shawnee Cattery deliberately bred an American Shorthair with a Burmese for the purpose of creating a domesticated cat that resembled a wild panther (also known as baby panther). The offspring of this breeding did indeed resemble the black leopard of India. The name came from the Indian city of Bombay (now Mumbai). Horner called her creation the “patent leather kid with the new penny eyes.”

Sphynx

The Sphynx (also known as the Canadian Hairless) is one of the newer cat breeds. It is reported that the first Sphynx was born in Canada in 1966, in Roncesvalles, Toronto when a hairless kitten named Prune was born. The kitten was mated with its mother (a process known as backcrossing), which produced one more naked kitten. The lack of hair on the Sphynx is caused by a genetic imbalance and occurs about once every fifteen years.

Despite the Sphynx appearing to be a hairless cat it is in fact not truly hairless. The skin will have the texture of chamois leather or a ripe peach. This covering is a very soft, fine down, which is almost imperceptible to both the eye.

Sphynx

Sphynx cat with typically large ears.

Lack of a thick coat makes the cat quite warm to the touch. Hair in the form of Whiskers and eyebrows may be present or may in some extreme cases be totally absent. It is said that the skin of this feline is the color their fur would have been had it been present, and all the usual cat marking patterns (solid, point, van, tabby, tortie, etc) may be found in Sphynx too. This is a very unusual trait.

The personality of the Sphynx is generally warm and friendly, highly intelligent, inquisitive and extroverted. They are also very affectionate and social animals. If kept as a pet the Sphynx should always have the company of others (be they other Sphynx or humans) so that they have companionship throughout each and every day. It is said to be cruel to keep a sphynx isolated for long periods.

Many people with typical allergies to cats with full fur coats find that they tolerate the Sphynx breed well. Because Sphynx don’t leave hair all over the house this is thought to make them an easier cat to keep. This is not strictly so! Their lack of hair results in increased body oils so regular bathing is often necessary, which is an inconvenience most cat owners dont have to deal with. Also the Sphynx will be going outdoors as often as your ‘common’ domestic cat (if at all) Care should be taken to limit the Sphynx cat’s exposure to outdoor sunlight as they can develop a sunburn, similar to that caused in humans. In general, Sphynx cats should never be allowed outdoors unattended, as they have limited means to conserve body heat in colder temperatures, and their curious nature can take them into dangerous places or situations.

The Sphynx breed is known for a sturdy, heavy body a wedge-shaped head and an alert friendly temperament. Although hairless cats have been reported throughout history (hairless cats seem to appear naturally about every 15 years or so), and breeders in Canada have been working on the Sphynx breed since the early 1960s, the current American and European Sphynx breed is descended from two lines of natural mutations:

Other hairless breeds might have different body shapes or temperaments than those described above. There are, for example, new hairless breeds, including the Don Sphynx and the Peterbald from Russia, which arose from their own spontaneous mutations. The standard for the Sphynx differs between cat associations such as TICA, FIFE and CFA.

Sphynx hairlessness is produced by a ‘strain’ of the same gene that produces the Cornish Rex, which has only one of the usual two fur coats. The Sphynx strain (or allele) is incompletely dominant over the Devon allele; both are recessive (or revert) to the wild type. Sphynx were at one time crossbred with Devon Rex in an attempt to strengthen this gene, but unfortunately this led to serious dental or nervous-system problems and is now forbidden in most breed standards associations. A genetic heart defect was also introduced by the Devon Rex breed. The only allowable out-cross breeds in the CFA are now the American Short-hair and Domestic Short-hair. Other associations may vary. In Europe mainly Devon Rex has been used for out-crosses.

Oriental Shorthair

The Oriental Shorthair breed is also called a “Foreign Type” cat. This cat combines the Siamese body with a diversity of colorings and patterns.

Oriental Shorthairs are intelligent, social animals who bond closely to their people. They are inquisitive, friendly, emotional, demanding and often quite vocal. Oriental Shorthairs have been likened to a Greyhound or a Chihuahua in appearance. Some people say they are ‘dog-like’ in personality, particularly because they become so attached to people.

Oriental Shorthairs

Oriental Shorthair – emotionally demanding and often quite vocal.

Description

The Oriental Shorthair is a self-coloured (non-pointed) member of the Siamese Family. They can be found in solid colors (white, red, cream, ebony, blue, chestnut, lavender, cinnamon, or fawn), smoke (white undercoat to any of the above except white), shaded (only the hair tips colored), parti-color (red or cream splashes on any of the above), tabby (mackerel/striped, ticked, spotted, and blotched/classic), and bi-colored (any of the above, with white). In total, there are over 300 color and pattern combinations possible. Though in CFA, pointed cats from Oriental Shorthair parents are considered Any Other Variety (AOV), in TICA, as well as in the majority of worldwide Cat Associations, these cats are considered to be, and compete as, Siamese.

Oriental Shorthairs have expressive, almond-shaped eyes, a wedge-shaped head with large ears that fit in the wedge of the head. Their bodies are very elegant yet muscular. When seeing an Oriental Shorthair, one would never guess them to be as solid as they are.

The longhaired version of the Oriental Shorthair, Oriental Longhair, simply carries a pair of the recessive long hair gene.

Origins

The Siamese cat was imported to Britain from Siam (Thailand) in the later half of the 1800s. According to reports, both pointed and solid colors were imported. The gene that causes the color to be restricted to the points is a recessive gene, therefore the general population of the cats of Siam were largely self (solid) colored. When the cats from Siam were bred, the pointed cats were eventually registered as Siamese the others were referred to as “non-blue eyed siamese” or foreign shorthair. Other breeds that were developed from the moggies of Siam include the Havana Brown and the Korat.

It was not until 1977 that the Oriental Shorthair was accepted for competition into the CFA. In 1985, the CFA recognized the bicolor oriental shorthair. The bicolor is any one of the accepted oriental shorthair color patterns with the addition of white to the belly, face, and legs/paws.

Manx Cat

The Manx is a breed of cats with a naturally occurring mutation of the spine. This mutation shortens the tail, resulting in a range of tail lengths from normal to tailless. Many Manx have a small ‘stub’ of a tail, but Manx cats are best known as being entirely tailless and it is the distinguishing characteristic of the breed and a cat body type genetic mutation.

Manx

Manx Cat with distinguishing stumpy tail

The Manx breed originated on the Isle of Man (hence the name), where they are common. They are called ‘stubbin’ in the Manx language.

They are an old breed, and these tailless cats were common on the island as long as three hundred years ago. The taillessness arises from a genetic mutation that became common on the island (apparently an example of the ‘Founder’ effect). The Manx tailless gene is dominant and highly transferable from generation to generation; kittens from Manx parents are generally born without any tail.

Having two copies of the gene is lethal to the animal and kittens are usually spontaneously aborted before birth in these cases. This means that tailless cats can carry only one copy of the gene. Because of the danger of having two copies of the tailless gene, breeders have to be careful about breeding two tailless Manxes together. Problems can be avoided by breeding tailless cats with tailed ones and this breeding practice is responsible for the decreasing occurrence of spinal problems in recent years.

There are various legends that seek to explain why the Manx has no tail.

In one of them, Noah closed the door of the ark when it began to rain and accidentally cut off the Manx’s tail, who’d been playing and almost got left behind. Another legend claims that the Manx is the offspring of a cat and a rabbit which is why it has no tail and rather long hind legs. In addition, they move with more of a hop than a stride, like a rabbit. This legend was further reinforced by the ‘Cabbit’ myth.

Recent postcards on the Isle of Man depict a cartoon scene of a cat’s tail being run over and removed by a motorbike, because motorbike racing is popular on the Island.

Long Haired Manx Cat

In appearance the hind legs of a Manx are longer than the front legs, creating a continuous arch from shoulders to rump giving the cat a rounded appearance.

Manx kittens are classified according to tail length:

* Dimple rumpy or rumpy – no tail whatsoever
* Riser or rumpy riser – stub of cartilage or several vertebrae under the fur, most noticeable when kitten is happy and raising its ‘tail’
* Stumpy – partial tail, more than a ‘riser’ but less than ‘tailed’ (in rare cases kittens are born with kinked tails because of incomplete growth of the tail during development)
* Tailed or longy – complete or near complete tail

Breeders have reported all tail lengths even within the same litter.

The ideal show Manx is the rumpy; the stumpy and tailed Manx do not qualify to be shown. In the past, kittens with stumpy or full tails have been docked at birth as a preventative measure due to some partial tails being very prone to a form of arthritis that causes the cat severe pain.

Manx cats exhibit two coat lengths. The short-haired Manx has a double coat with a thick, short under-layer and a longer, coarse outer-layer with guard hairs. The long-haired Manx, known to some cat registries as the Cymric, has a silky-textured double coat of medium length, with britches, belly and neck ruff, tufts of fur between the toes and full ear furnishings. The Cat Fanciers’ Association (CFA) considers the Cymric to be a variety of Manx and judges it in the short-hair division, while The International Cat Association (TICA) judges it in the long-hair division. Short- or long-haired, all Manx have a thick double-layered coat.

In health the pedigreed Manx cats today are much healthier and have fewer health issues related to their genetics than the Manx of years ago. This is due in part to the careful selection of breeding stock, and knowledgeable, dedicated breeders. Manx have been known to live into their mid to late teens and are no less healthy than other cat breeds.

Like any other cat, keeping Manx cats indoors, neutering or spaying, and providing acceptable surfaces for the cat’s normal scratching behavior are vital to lengthen the life of any cat.

British Longhair

The British Longhair cat is a semi-longhair version of British Shorthair. Apart from fur, it is identical to the British Shorthair. The British Longhair is also known as Lowlander in U.S. and Britanica in Europe, but is not recognised in the UK as a separate breed.

The rationale for this breed is that the original longhaired British cat, through interbreeding with imported longhairs, was developed into the Persian and became increasingly massive and extreme in type and with longer, thicker fur than the early Persians. During the late 19th Century and early 20th Century, the Persian was considered the longhaired analogue of the British Shorthair (Frances Simpson’s The Book of the Cat depicts and describes the old type of Persian).

During the latter part of the 20th Century a shorthaired version of the modern Persian was developed and was called the Exotic Shorthair; this was very different from the British Shorthair. It was therefore proposed that a longhaired cat of the British type be reintroduced into the cat breeds.
