Origins and history

The Cornish Rex was born on a farm in Cornwall (UK). The first kitten displayed frizzy hair, reminiscent of Rex rabbits. As this genetic mutation is recessive in nature, it took many inbreeding crossings to maintain this coat. Of course, breeding with other breeds such as the Siamese or the Burmese, for example, has diversified this new breed that was first recognised in 1967 in England.
