The Cornish Rex is a genetic mutation that originated from a litter of kittens born in the 1950s on a farm in Cornwall, UK[3] One of the kittens, a cream-colored male named Kallibunker, had an extremely unusual, fine and curly coat; he was the first Cornish Rex. The owner then backcrossed Kallibunker to his mother to produce 2 other curly-coated kittens. The male, Poldhu, sired a female called Lamorna Cove who was later brought to America and crossed with a Siamese, giving the breed their long whippy tails and big ears.
