The Selkirk Rex is a breed of cat with highly curled hair, including the whiskers (vibrissae). 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, and there are longhair and shorthair varieties. This demonstrated that the gene had an autosomal dominant mode of inheritance. All Selkirk Rex trace their ancestry back to Miss DePesto. The breed has been developed in two coat lengths, long and short (medium). It is a large and solidly built breed, similar to a British Shorthair.
