Cats normally have 18 toes (5 on each fore paw and 4 on each hind paw), but Polydactyl cats can have as many as 8 toes on any one paw. Guiness World Record-holding Polydactyl cats had 28 toes!

Polydactylism is a genetically inherited abnormality. No one breed of cat is more or less likely to be polydactyl -- all breeds are susceptible to having the trait for extra paws.

American Polydactyls are also referred to as Hemingway Cats because writer Ernest Hemingway was so fond of them that his home in Key West currently houses around 50 descendants of his polydactyl friends.
