The Selkirk Rex name comes from the Selkirk Mountains near where the breed originated in Montana, combined with "Rex," a term used in cat fancy to denote curly or wavy coats. The breed's founder, Jeri Newman, named the breed after her stepfather's family surname, making it the first cat breed named after a person. This naming convention distinguishes Selkirk Rex from other Rex breeds like Cornish Rex or Devon Rex, which are named after their geographic origins.
Within the Selkirk Rex breed, there are two coat length varieties: shorthaired and longhaired. Both varieties share identical breed standards aside from coat length and grooming requirements. The longhaired variety is sometimes specified as "Selkirk Rex Longhair" or "Longhair Selkirk Rex" to distinguish it from the shorthaired variety. However, both are considered the same breed—Selkirk Rex—with coat length being the only significant difference. Both varieties can appear in the same litter.
The breed is sometimes nicknamed "the cat in sheep's clothing" or "poodle cat" due to the distinctive curly coat that resembles sheep's wool or a poodle's curls, particularly in the longhaired variety. These whimsical nicknames capture the breed's unique appearance and soft, plush texture. Some enthusiasts also call them "teddy bear cats" when referring to their cuddly, affectionate nature combined with their soft, curly coats.
No official alternate names exist beyond casual nicknames and coat length specifications. The breed is universally registered as "Selkirk Rex" across all major cat registries that recognize them, with coat length noted as a variety rather than creating separate breed names. The consistency in naming helps maintain breed identity while acknowledging the two coat length options.
The Selkirk Rex is officially recognized by all major cat registries including The International Cat Association (TICA), which granted championship status in 1992, and the Cat Fanciers' Association (CFA), which granted championship status in 2000. Other registries including the American Cat Fanciers Association (ACFA) and international organizations also recognize the breed. This widespread recognition reflects the breed's appeal and the responsible development program established by early breeders.
Both shorthaired and longhaired Selkirk Rex are equally valued and shown in cat shows, with separate divisions for coat length in most registries. The longhaired variety often shows more dramatic curl and presentation due to their longer fur, though both varieties display the characteristic curly coat equally. Some people prefer one coat length over the other based on aesthetic preferences or grooming considerations, but both represent the breed equally.
The Selkirk Rex is one of four Rex breeds, each with distinct curl types and origins. Cornish Rex and Devon Rex have very different coat textures and body types—they're fine-boned with short, wavy coats. The LaPerm has a different curl pattern. Selkirk Rex stands apart with a more substantial, moderate body type and plush, loose curls rather than tight waves. The distinction between Rex breeds is important in breeding programs and show competition.
