Instead of loud miaowing when your cat wants food (behaviour likely to have them sent packing from the bedroom), some cats disguise their cries for attention within an otherwise pleasant purr.

Ahhh, your Mog is sleeping yes?.... or is he secretly planning new ways to get fish suppers out of you? - The jury's out

The result, according to a study published recently in the journal 'Current Biology', is a "begging" purr with a high-frequency element that triggers a sense of urgency in the human brain. Owners find it irritating, but not irritating enough to kick the cat out, and feel driven to respond.

Dr Karen McComb, a specialist in mammal vocal communication at the University of Sussex, said that by employing an embedded cry, cats appear to be exploiting hidden tendencies that humans have for nurturing offspring.

She went on to say that - the embedding of a cry within a call that we normally associate with contentment is quite a subtle means of getting a response – and solicitation (begging) purring is probably more acceptable to humans than the usual meowing,.

McComb, whose usual subjects include African elephants and lions in the wild, began the research into domestic cats after noticing the "manipulative" purring of her own cat, Pepo. "I wondered why this purring sounded so annoying and was so difficult to ignore," she said. "Talking with other cat owners, I found that some of them also had cats which showed similar behaviour."

After testing human responses to different purring types, McComb and her team found that even those with no experience of cats judged the "solicitation" purr to be more urgent and less pleasant.

On examining the frequency of the special purr, she found a peak similar to that of a baby's cry, which gave it a "noisy, slightly whiny quality".

However, not all cats have the cry; the researchers, who examined 10 cats, found it only in those living in single-person households. "We found that cats learn to dramatically emphasise the peak when dealing with human owners that have a one-on-one relationship," McComb said.

Asked whether the cat's special purr is more effective than a dog's bark, or other demand for food, she said: "I think it might be more effective than a dog. If you ask people who own cats what they do when they get up they say they feed their cats. Even before they have a cup of coffee. Cats are very good at getting their own way."

(well this doesn't apply to our Norman for sure!) Ed.
.....but, er, come to think of it...

Here are some of the cat classifications I've found whilst looking at the different breeds and 'house cats'. There are probably many others. Please comment with any new classification you may have heard of and I'll add it in

"American Keuda"
An emerging breed of cat. The Keuda is under active development, however it has already become semi-standardized. If it were recognized by a major cat registry, it would probably be classified as a "Provisional" breed, but the desired characters are not entirely developed and/or stable).

"Bi-colour"
The bi-colour cat has white fur mixed with fur of other colors, an example would be black or cream. They come in different patterns. These range from color on the crown of the head and the tail only, or a solid color with a small mark of another color.

"Domestic longhaired"
The domestic longhaired cat is a term used to describe a cat with medium or long hair that is not a pedigreed member of a recognized breed. Domesticated longhairs appear in all standard cat colours including cream, tortie, smoke etc.

"Domestic shorthaired"
The domestic shorthaired cat,is a term used to describe a shorthaired cat that does not have a pedigree or belong to a recognized cat breed. The domesticated shorthair should not be counted as an American shorthair. Domesticated shorthaired cats are found in a wide range of colours. They also show a wide range of physical behaviors and, as a result, domesticated shorthaires in different countries look different in body shape and size.

"Dwarf"
This is a domesticated cat breed which has mutated to dwarfism due to a genetics.The Munchkin is the founding breed of the chondrodysplastic cat.

"Farm"
Farm cats are also called barn cats, these cats are kept primarily for catching smaller vermin found on farms and ranches. otherwise the vermin would eat and/or contaminate the farmer's crops. They are often semi-wild, and caution should be used around them.

"Feral"
This cat is unowned and untamed, it is not domesticated. Feral cats may be born in the wild and never socialized. They should not be confused with the wildcat which are not descended from domestic cats.

"Maltese"
This is a name that is often given to any cat, whose fur is either completely, or primarily, gray or blue,and not pedigree. Many with such colouration inhabit the island of Malta, which may have given rise to the name.

"Moggy"
This is a British term for a domestic cat, it is also used to call a mongrel or mixed-breed cat. Because of this mixed ancestry and free-breeding, a moggy can either be very healthy, or, sickly.

"Odd-eyed"
This is a cat with one blue eye and one green eye or yellow or brown eye. It is a cat form of complete heterochromia. This is a condition that occurs in some other animals also. The condition most often affects white colored cats.

"Polydactyl"
A cat with a congenital physical deformity,it may have more than the usual number of toes on one or all of its paws. this is due to a genetic mutation. In animals including humans, polydactyly is the anatomical abnormality of having more than the usual number of toes or fingers.

"Smoke"
Is the name given to the cat colour in which the bottom eighth of each hair is white or creamy-white, with the rest of the hair being a solid colour. Smokes will look solid coloured until they move, then the white undercoat becomes visible. It is mostly found in pedigreed cats.

"Squitten"
This is a word derived from the words squirrel and kitten, it is a term used to describe a cat with unusually short forelegs or unusually long hindlegs that resembles a squirrel. Sometimes the term kangaroo cat is used; this derives from a 1953 specimen known as the Stalingrad Kangaroo Cat.

"Tabby"
This is a cat with a distinctive coat that features dots,stripes or swirling patterns. Tabbies are not a breed of cat, in fact, the tabby pattern is a naturally occurring feature that may be the original colouration of the domestic cat's ancestors. Tabby colour is found in many breeds of cat, as well as among the general 'moggy'. The tabby usually has an "M" mark on its forehead.The word comes from French 'tabis' and in medieval Latin 'attabi'. The initial origin of the word seems to be from Baghdad where a type of striped silk was made that was later used to describe cats.

"Tortoiseshell"
This beauty has a coat coloring with patches of black,red and chocolate, or cinnamon. They are sometimes called 'torties'.The term "tortoiseshell" is typically reserved for cats with coats that have relatively few or no white markings. Those that are largely white with red and black patches are described as tortoiseshell-and-white or calico.

"Black"
It is called a felid the fur is uniformly all black.It is not a particular breed of cat and may be mixed. The all-black pigmentation is equal in both male and female cats. The black color is of benefit to a cat hunting at night. They can camouflage in the darkness. In Western history, black cats have often been looked upon as a symbol of evil omens: in other cultures they are considered to be good omens. cat-categories continued.

Of all the carnivores, cats are the most highly adapted for hunting and devouring their prey. All cats have short muzzles,rounded heads, large eyes, and sensitive whiskers. Their ears are erect and pointed. They have short jaws and long canine teeth. Cats have five toes on the front feet and four on the rear feet. The ends of the toes bear sharp, strong, curved claws. The claws are completely retractile, being withdrawn into protective sheaths when not in use.

Just stumbled on this post. Interesting stuff. I know lots of folks who kiss their cats (including myself). Now there's a revelation. This article does make you think about cat handling issues. I'm sure (from my own experience) that it's mainly the young and elderly who are most at risk....here's the short article.

I'd be interested to hear any 'tales' you might have of cat ailments you've caught?

Steps to Prevent Disease Transmission from Cats to Man

• 1. Wear gloves when handling cats, or their body products such as: urine, feces, blood, nasal discharges, fluids draining from wounds. After removing your gloves, wash your hands with soap and water.
• 2. Never eat, drink or smoke in areas where cats, their wastes, or body products are being handled. Absolutely no eating, drinking or smoking is allowed where cats are housed.
• 3. Report all suspected sick cats as soon as possible so that a veterinarian may determine the cause of the illness and implement any additional protective steps.
• 4. Although a normal, healthy adult person may have only mild symptoms of a particular zoonotic disease, that person may spread the disease to others. Cases of animal handlers "carrying home" zoonotic diseases to their infants, with fatal consequences have occurred. Therefore, good hygiene is not only to protect the person working directly with cats, but all persons with whom they have contact.

At special risk are persons who may have a suppressed immune system, such as: infants, the elderly, people who have had their spleens removed, and people with long-term or debilitating conditions such as cancer, diabetes, AIDS and renal failure.

The list of possible zoonotic diseases is extensive and this module only attempts to highlight a few which are more commonly found.

ALLERGIC SENSITIVITIES Allergic skin and respiratory reactions are quite common in personnel working with cats and other animals. Consult your physician. Wear protective clothing to prevent direct contact with cats, waste, carcasses and other body products.

CAT SCRATCH FEVER caused by Bartanella henselae causes regional lymphadenitis usually associated with a history of a scratch or bite by a cat. Cat-scratch disease is usually self-limited; however in the presence of the HIV, causes severe disease.

RABIES This virus is transmitted by infected saliva, usually by a bite wound, but viral laden saliva may enter preexisting wounds or abrasions. The virus travels up a nerve to the spinal cord and finally reaches the brain. After a variable incubation period, rabid animals or humans will exhibit signs related to central nervous system (CNS) disfunction, and once this occurs, death is inevitable! For this reason, persons bitten by cats should always see a physician and discuss the correct course of treatment. Most animal caretakers will choose to take a series of pre-exposure vaccinations, which will facilitate treatment should they ever be bitten by an infected cat. Cats may be infected by exposure to infected bats.

RINGWORM caused by Microsporum canis is a highly contagious fungal disease. It occurs most often in temperate and tropical climates. People become infected by touching a contagious cat and then failing to wash their hands. When a cat is confirmed positive people should wear protective clothing such as a gown and gloves. Asymptomatic animals may also contaminate and infect susceptible people.

TOXOPLASMOSIS caused by Toxoplasma gondii. Clinical infections are relatively uncommon, but extremely hazardous. The method of exposure is through the feces, therefore wearing gloves when cleaning litter boxes is very important.

Despite all this, I know I for one wouldn't be without my moggy!
