In page Sphynx cat:

"

The Canadian Sphynx breed was started in 1966 in Toronto, Ontario when a hairless male kitten named Prune was born to a black and white domestic shorthair queen (Elizabeth).[1] The kitten was mated with his mother (called backcrossing), which produced one more naked kitten. Together with a few naked kittens found later, the cat Prune was the first attempt to create a hairless breed.[citation needed]
