One of the polydactyl cats at the Ernest Hemingway House in Key West, Florida.This particular cat has seven (two extra) toes on each paw. A polydactyl cat is a cat with a congenital physical anomaly called polydactyly (also known as polydactylism or hyperdactyly), which causes the cat to be born with more than the usual number of toes on one or more of its paws.
Polydactyly also occurs in dogs, cats, and small mammals such as guinea pigs [78] and mice. [79] Cats normally have five digits on the front paws and four on the rear. Polydactyl cats have more, and this is a moderately common condition, especially in certain cat populations.
There are probably many genes, both dominant and recessive, that cause polydactyly in cats. Most cases of polydactyly in cats are perfectly harmless. Pd Thumb-cat polydactyly gene. The Pd gene (dominant with incomplete penetrance) causes the benign, pre-axial form of polydactyly where one or more extra toes occur near the dew claw.

A well-known example is polydactyly in Hemingway’s cats, which is the presence of extra toes. The number of extra toes can differ between cats, due to variable expressivity of the ZRS gene in the feline chromosome A2. ZRS enhances the activity of the SHH gene, which is involved in limb development, and this has been shown to cause extra toes.
