Some cats have traits that make them unique, and being Polydactyl is just one of them. In fact, sailors once thought Polydactyl cats had a greater advantage when catching rats on their ships because of their extra toes. The condition is more common in cats than you might think.

However, Polydactyl cats are not inbred, and having a Polydactyl cat is no different than having a cat with one blue and one brown eye or a kitten with unusual, patterned colors. In this article, we’ll tell you a little of what you need to know about Polydactyl cats.


What Is a Polydactyl Cat?

A Polydactyl cat is born with six or more extra toes on one or all feet. Many polydactyl felines have at least 18 toes, consisting of five on the front paws and four on the back. However, as with any other animal, it can vary in each cat.

What Are the Side Effects of Polydactyly in Cats?

There are a few minor side effects of polydactyly in cats, namely:

  • Irregular nail growth
  • Pain
  • Injury
  • Overgrown nails
  • Infections of the nail bed

Types of Polydactylism

There are two types of Polydactylism in cats:

  • Preaxial Polydactyly: Where the extra digit grows in before the dewclaw.
  • Postaxial Polydactyly: When the extra digit grows after the fourth toe or phalange.

Your veterinarian can help you determine which type of polydactyly your cat has.

What Causes Polydactyly in Cats?

Polydactyly is a genetic condition that cats inherit, a mutation passed down from the parents to the kitten. This gene will override the other normal genes, resulting in the extra toes. If one parent has the Polydactyl gene and the other doesn’t, it’s still highly likely that the offspring of the two parents will develop the condition anyway. It’s interesting to note that Maine Coon cats are the most common cats to see with Polydactyly.

Can Polydactyly in Cats Be Treated?

It’s usually pretty easy to diagnose Polydactyly as the extra digits are easy to see. However, if you’re unsure, your vet can determine if you have a polydactyl cat and if they need to be treated for any of the symptoms that may occur. The condition doesn’t typically require surgery, but your veterinarian will discuss this option with you if they feel it is necessary, especially if the extra toes are causing an issue. hepper-cat-paw-divider

Final Thoughts

Polydactyl cats are not inbred, but they have a genetic condition passed down from one of their parents. Though it may not be a big deal for your kitten, it’s best to talk to your vet to see if they think a treatment is needed to keep your cat healthy and happy.
