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.
Munchkin or dwarf cat gene (dominant). Cats heterozygous for this gene (Mkmk) have shortened and thickened legs, because this gene causes dwarfism in cats. Cats with this mutation have lived naturally in feral populations worldwide. However, cats with this gene are also the basis for several intentionally selected breeds of dwarf cat.
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

Mutations in this gene also cause white spotting. [9] Since a large variety of coat patterns exist within the various cat breeds, the cat is an excellent animal to study the coat genetics of hair growth and coloration. [10] Several genes interact to produce cats' hair color and coat patterns.
ZRS enhances the activity of the SHH gene, which is involved in limb development, and this has been shown to cause extra toes. Although polydactyly is caused by an autosomal dominant allele , the variable expressivity (number of toes) of polydactyly in cats may be influenced by the tissues surrounding the region that would develop into toes.
