This is a medium to large cat with heavy boning that gives the cat surprising weight and an impression of power. It has a chunky build, short muzzle and a round head. Selkirk Rex cats can be long- or short-haired. All three types of coat hair – guard, awn and down hairs – are found in the Selkirk Rex cat breed and they are all wavy, giving the coat a soft feel. The curliness of the coat varies with age, gender, climate and season. In the Selkirk Rex Longhaired cat breed, the tail curls are plumy and stand out away from the tail. The ruff hairs are longer and frame the face. Selkirk Rex cats come in all coat colours and patterns.
