History & Origin
The Cornish Rex originated from a single curly-coated kitten named Kallibunker, born on a farm in Cornwall, England in 1950. The kitten's owner, Nina Ennismore, noticed his unusual coat and began breeding him to establish the trait. The breed was brought to the US in 1957 and recognized by the CFA in 1964.
