Addictional informatio n (Wiki): 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. It differs from the LaPerm in that its coat is more plush and thick and although both have dominant Rex genes they behave in different ways. While the LaPerm gene is a simple dominant, the Selkirk gene (Se) acts as an incomplete dominant; incompletely dominant allele pairs produce three possible genotypes and phenotypes: heterozygous cats (Sese) may have a fuller coat that is preferred in the show ring, while homozygous cats (SeSe) may have a tighter curl and less coat volume.

The Selkirk Rex originated in Montana, America in 1987, with a litter born to a rescued cat. The only unusually coated kitten in the litter was ultimately placed with a Persian breeder, Jeri Newman, who named her Miss DePesto (after a curly-haired character in the TV series Moonlighting played by Allyce Beasley). This foundation cat was bred to a black Persian male, producing three Selkirk Rex and three straight-haired kittens. This demonstrated that the gene had an autosomal dominant mode of inheritance. All Selkirk Rex trace their ancestry back to Miss DePesto.
