The Cornish Rex is the greyhound of the cat world -- a lean, athletic, arched-back feline with a coat of tight marcel waves and an energy level that never diminishes. They are acrobatic, attention-seeking, and permanently stuck in kitten mode. If you want a couch ornament, look elsewhere. If you want an interactive, clownish, warm-bodied companion -- the Cornish Rex delivers.

Frequently Asked Questions
Do Cornish Rex cats need sweaters?
In cold weather, yes. Without guard hairs, Cornish Rex cats lose body heat quickly. They naturally seek warm spots (radiators, laptops, under blankets, on your lap). In air-conditioned homes or cold climates, a cat sweater is genuinely practical rather than just cute. They are one of the few breeds where clothing serves a functional purpose.
