Sphynx

Cat

The Sphynx is a rare breed of cat known for its lack of a coat. The contemporary Mutant breed of Sphynx (known also as the Canadian Sphynx, distinct from the Russian Sphynx breeds - Peterbald, Don Sphynx) started in 1966, in Roncesvalles, Toronto when a hairless kitten named Prune was born. The kitten was mated with its mother (backcrossing), which produced one more naked kitten. Together with a few naked kittens found later it founded the first attempt to create a hairless breed. The first sphynx breeders faced a number of problems: The genetic pool was very limited; breeders had rather vague ideas about sphynx genetics, and many kittens died. There was also a problem with many of the females suffering convulsions. The last 2 descendants of Prune, a brother-sister pair, were sent to Holland in the 1970s, but the male was uninterested in mating and the female conceived only once, but lost the litter.
