Overview

The Cornish Rex is an athletic, fine-boned cat distinguished by its unique curly coat that consists only of the soft undercoat, with no coarse guard hairs. Often described as resembling a tiny greyhound, it has a slender, arched body, long legs, large ears and an egg-shaped head. These cats are extremely active, agile and acrobatic, and they form strong bonds with their humans, frequently seeking laps and warmth. Their warm-feeling coat and playful, dog-like devotion make them popular companions for attentive households.

History and Origin

The Cornish Rex began in 1950 on a farm in Cornwall, England, when a curly-coated kitten named Kallibunker was born in a litter of ordinary barn cats. Breeders worked with this natural mutation, later outcrossing to breeds such as the Siamese, British Shorthair and others to expand the gene pool. The breed reached the United States in 1957 and was further developed there. It gained championship recognition from CFA in 1964 and is now accepted by major registries including TICA and CFA.
