District council elections in England A polydactyl cat is a cat with a congenital physical anomaly called polydactyly (or polydactylism, also known as hyperdactyly), which causes the cat to be born with more than the usual number of toes on one or more of its paws.

Some cases of polydactyly are caused by mutations in the ZRS, a genetic enhancer that regulates expression of the Sonic Hedgehog (SHH) gene in the limb.

Normal cats have a total of 18 toes, with five toes on each fore paw, and four toes on each hind paw; polydactyl cats may have as many as nine digits on their front or hind paws.

Both Jake, a Canadian polydactyl cat, and Paws, an American polydactyl cat, were recognised by Guinness World Records as having the highest number of toes on a cat, 28.

Polydactyly is most commonly found on the front paws only; it is rare for a cat to have polydactyl hind paws only, and polydactyly of all four paws is even less common.

Contributing to the spread of polydactyl cats by this means, sailors were long known to value polydactyl cats especially for their extraordinary climbing and hunting abilities as an aid in controlling shipboard rodents.

The rarity of polydactyl cats in Europe may be because they were hunted and killed due to superstitions about witchcraft.

Genetic work studying the DNA basis of the condition indicates that many different mutations in the same ZRS area can all lead to polydactyly.

Nobel Prize-winning author Ernest Hemingway was a famous aficionado of polydactyl cats, after being first given, by a ship captain, a six-toed cat he named Snow White.

Upon Hemingway's death in 1961, his former home in Key West, Florida became a museum and a home for his cats, and it currently houses approximately fifty descendants of his cats (about half of which are polydactyl).

Because of his love for these animals, polydactyl cats are sometimes referred to as "Hemingway cats".

Nicknames for polydactyl cats include Hemingway cats, mitten cats, conch cats, boxing cats, mitten-foot cats, snowshoe cats, thumb cats, six-fingered cats, and Cardi-cats.
