Addictional informatio n (Wiki): 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.

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, they might get hypothermia if they stay outdoors in the winter. Their body temperature is slightly higher than most cats (102 F), and these cats tend to hang around light bulbs, the tops of computer monitors, and other warm places including laps and shoulders. Some Cornish Rexes also have a mild cheesy smell peculiar to the breed; this odour comes from scent glands in the paws.

Often the breed is referred to as the Greyhound of the cats, 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. Some humans consider its antics to be deliberately mischievous. 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.
