Facts About Polydactyl Cats

Usually, most cats have four toes on the back and five toes on the front paws, but when it comes to polydactyl cats, they have six or seven toes (or more) on each. The word comes from Greek: “poly” meaning many and “daktulos” which means fingers. 

Polydactylism in cats is a genetic mutation. In this condition, the offspring are born with extra fingers. This genetic aberration is prevalent in a few different parts of the world, and it can afflict both males and females of any breed, large or little.

What impact does genetic mutation have on polydactyl cats?

The genetic mutation usually occurs in a dominant gene in polydactyl cats. Which in term produces the greater number of toes in cats, affected cats can have a number of toes between 4 and 7 on their front or rear legs. 

In most cases, it is seen that generally, the front paws are affected more frequently, but it doesn’t mean that the back leg will not get affected by polydactylism. In some cases, the polydactyl is also seen to affect all paws on a cat, but it is not that common.

Polydactyl is generally thought to have no influence on your cat’s well-being or health, hence it is regarded as a harmless mutation. Having more fingers than usual has only one drawback: it makes nail clipping more difficult. If you’ve ever tried trimming your cat’s nails yourself, you know how exhausting it can be, especially if you have extra claws to clip.

What is the difference between polydactylism and feline radial hypoplasia?

With feline radial hypoplasia you will also see the development of extra new toes. But the difference between those two terms is the immediate development of new toes alongside the feline’s usual toes that can result in extra-large, flat feet. If the cat is raised with radial hypoplasia, this can result in severe leg deformities in future new generations.

Because many individuals conflate the phrases polydactyl and feline radial hypoplasia, it would be helpful if you kept in mind that the two are completely different. Feline radial hypoplasia can have a negative impact on your cat’s health and is thought to be quite dangerous.

What are “mittens” in polydactyl cats?

Some polydactyl cats are seen with mitten paws. This can only happen if the extra toes appear in the middle of your cat’s claw, giving it a mitten or thumb appearance. The extra fingers resemble the thumbs, but they should not oppose each other.

Polydactyl May Benefit few Cats

You see, some cat owners who don’t like the extra toes on their cats’ paws actually hate polydactylism, but they need to know that these paws are not harmful but beneficial for some kitties as well. Due to the extra toes in the polydactyl cat, they have larger paws that allow them to hunt, capture, climb, and balance more efficiently on different surfaces.

If you’ve been blessed with a polydactyl cat, make sure you have a scratching board or post for her. If you are not going to use a scratching post for your kitty, you may find your furniture scratched.

Superstitions about polydactyl cats

Polydactyl cats are also considered lucky cats by some and are believed as a good luck for travelers and sailors. Because of this, polydactyl cats were also brought along on long ship trips.

The extra digits broaden their paw, allowing them to keep the ship’s supplies vermin-free and clean the ship of mice. Their large paws also aid in their balance during rocky times onboard the ship

Prevalence of polydactyl cats

As they are considered the lucky charm for sailors, they are mainly found in Canada, Wales, the eastern United States and England. The prevalence of polydactyl cats in those areas is often attributed to their time on transcontinental ships.

It is widely believed that in England, polydactyl cats were bred with non-polydactyl cats. They were transported across the Atlantic Ocean, and this is how their genetic traits proliferate.

Why polydactyl is prevalent in Maine Coon cats?

Maine, which is known for its harsh, snowy climate, is the birthplace of this cat species. With time, these cats developed large, insulated feet that serve as miniature snowshoes.

Maine Coons are the most prevalent polydactyl cats, accounting for about 40% of all unregistered Maine Coons. Polydactylism gave the Maine Coon wider paws, which helped them get through the tough, snowy conditions.

Hemingway’s six-toed cats

You may have heard of them as Hemingway’s cats. Ernest Hemingway had great affection for the polydactyl cats. He was given a white cat named Snow Ball by the captain of a ship and that cat happen to be polydactyl.

After the death of Hemingway in 1961, his residence was converted into a home for his lovely cats and a museum in Key West, Florida. Now-a-days, the kitten colony has about 50 family members of the creative pack of cats, and nearly half of those cats are polydactyl.
