Cornish Rex

A Cornish Rex is a breed of domestic cat. The Cornish Rex has no hair except for down. Most breeds of cat have three different types of hair in their coats: the outer fur or "guard hairs", which is about 5 cm long in shorthairs and 10cm+ long in longhairs; a middle layer called the "awn hair"; and the down hair or undercoat, which is very fine and about 1 cm long. Cornish Rexes only have the undercoat. The curl in Cornish Rex fur is caused by a different mutation and gene than that of the Devon Rex. It originates from Cornwall, England.

The coat of a Cornish Rex is extremely fine and sometimes curly, the softest of any cat breed. However, their light coat means that they are best suited for indoor living in warm and dry conditions, as they might get hypothermia if they stay outdoors in the winter. Their body temperature of 39 °C (102 °F) is slightly higher than that of most cats, with Cornish Rexes tending to hang around warm places such as computer monitors, light bulbs, laps and shoulders. Some Cornish Rexes also have a mild cheesy smell peculiar to the breed; this odor comes from scent glands in the paws.

Often the breed is referred to as the Greyhound of the cats (source: Animal Planet television series: "Cats 101" episode:"Colorpoint Shorthair"), because of the sleek appearance and the galloping run characteristic of the breed. These cats tend to stay playful and kittenish throughout their long lives. Some Cornish Rexes like to play fetch, race other pets, or do acrobatic jumps. The Cornish Rex is an adventurous cat and is very intelligent. It can readily adapt to new situations and will explore wherever it can go, jumping into refrigerators, examining washing machines, etc. The Rex is extremely curious, seeks out the company of people and is friendly towards other companion animals. It is a suitable pet for timid children.

Cornish Rex cats come in a wide variety of coat colours and patterns, outlined in the breed standard: solids, including white, black, chocolate, orange and the dilutes blue, lilac and cream; all forms of tabby including classic, mackerel and ticked tabbies, bicolor "tuxedo" coat in many colours, tortoiseshell, "smoke" colours and the colour-point pattern standard in the Siamese breed.
