The Selkirk Rex originated in Montana, USA in 1987, with a litter born to a rescued cat. The only unusually coated kitten in the litter was ultimately placed with breeder, Jeri Newman.
It is distinct from all other Rex breeds. Unlike the Devon Rex and Cornish Rex, the hair is of normal length and not partly missing. There are longhair and shorthair varieties.
The Selkirk Rex breed has been developed in two coat lengths, long and short. It is a large and solidly built breed, similar to a British Shorthair. The coat is very soft and has a woolly look and feel with loose, unstructured curls. The head is round, with large rounded eyes, medium-sized ears, and a distinct muzzle, whose length is equal to half its width.
