The Cornish Rex began with a curly-coated kitten born on a Cornwall farm in 1950, the result of a natural recessive mutation. The coat has only the soft down layer, lying in tight waves, and it covers a lean, long-legged body with an arched back, an egg-shaped head and very large ears. Most adults weigh about 6 to 10 pounds.
Many Rexes stay playful and people-focused well into adulthood, fetching toys and following their humans around. In Albuquerque, where winter nights often fall below freezing and the high-elevation sun is strong, the thin coat matters: it offers little protection from cold or sunburn, so a Rex belongs indoors with warm places to rest. The coat sheds little but isn't hypoallergenic, and baths and ear cleaning are part of the routine.
