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
Normally, cats have eighteen toes—five on each front paw and four on each back paw. However, the gene for polydactyly can cause a various number of toes to appear, from a simple extra thumb to ...
Cat genetics describes the study of inheritance as it occurs in domestic cats. In feline husbandry it can predict established traits ( phenotypes ) of the offspring of particular crosses. In medical genetics , cat models are occasionally used to discover the function of homologous human disease genes.
A squitten is a cat with a genetic deformity which causes a partial formation or complete absence of the radius bone making it resemble a squirrel. These cats should be kept indoors and seen to by specialist veterinarians, as long term management of the condition is essential for quality of life in these cats. [ 1 ]
Waardenburg syndrome type 2A (caused by a mutation in MITF) has been found in many other small mammals including dogs, minks and mice, and they all display at least patchy white depigmentation and some degeneration of the cochlea and saccule, as in deaf white cats. [10] [11] A major gene that causes a cat to have a white coat is a dominant ...
