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

Russian Blue

The Russian Blue is characterised by a dense, plush, blue-grey coat with silver-tipped hairs and vivid green eyes. Its origin is traditionally linked to Arkhangelsk, but this is not known for certain. Adults typically weigh around 3 to 5.5 kilograms, with a graceful, long-legged body. The coat is double but easy to look after, and brushing a few times a week is enough. The breed is usually quiet, reserved with strangers and strongly attached to its own family. The standard calls for a solid blue coat without spots or patterns. Russian Blues are long-lived, typically reaching around 12 to 18 years.
