Cornish Rex

The Cornish Rex arose in Cornwall, England, around 1950, when a kitten with a wavy coat was born. Its coat is short, soft and wavy because it is made up only of down hairs, without the outer guard hairs. The body is slender and long-legged, the head is narrow and the ears are large. Adults typically weigh around 2.5 to 4.5 kilograms. Because of the thin coat, it often seeks warmth. Little grooming is needed, and the coat is better stroked than brushed. Cornish Rex cats are usually energetic, playful and attached to people. Life expectancy is typically around 12 to 16 years.

Category IV — Siamese and Oriental

Siamese

The Siamese comes from Thailand, formerly called Siam, and spread through Europe in the late nineteenth century. It has a pale body with darker markings on the face, ears, legs and tail and vivid blue, almond-shaped eyes. The body is lean and long-legged, and the head is wedge-shaped. Adults typically weigh around 2.5 to 5.5 kilograms. The short, smooth coat needs little grooming. Siamese cats are known for being talkative, intelligent and strongly attached to people, and they need attention and interaction. Kittens are born almost white, and the darker markings develop over the first weeks. Life expectancy is typically around 12 to 16 years.
