Have you ever noticed a cat with what looks like thumbs? Some cats are born with extra toes, a unique condition known as polydactyly. These "thumb cats" often draw attention due to their unusual paws, and their distinct appearance makes them even more lovable to cat enthusiasts. But what exactly causes this phenomenon, and is it something that impacts the health or happiness of our feline friends?

In this blog, we'll explore what causes polydactyly in cats, why certain cats are blessed with extra toes, and how these unusual paws have even found their way into pop culture. Whether you're curious about Polydactyl Cats or simply want to know more about caring for a cat with thumbs, we've got the facts to satisfy your curiosity.

What is Polydactyly?

Polydactyly is a genetic condition that results in a cat being born with extra toes on one or more of its paws. While most cats have five toes on their front paws and four on their back paws, a Polydactyl Cat may have six or more toes on each foot. These extra digits can make the cat's paws look like they have thumbs, which is why they are often called "thumb cats."

This genetic trait is not harmful to the cat and does not typically interfere with their daily activities. In fact, many cats with this condition are just as agile and active as cats with the standard number of toes. The extra toes are merely an additional feature that makes these cats unique and charming. Although polydactyly can occur in cats of any breed, it is especially common among certain breeds, such as the Maine Coon, where the trait is considered a mark of distinction.

In the past, polydactyl cats were particularly popular among sailors, who believed that these "thumb cats" brought good luck on long sea voyages. Their extra toes were thought to help them balance better on ships in rough waters, making them not only lucky but also useful companions for sailors.

What Causes Polydactyly in Cats?

Polydactyly in cats is caused by a genetic mutation. This condition is inherited in an autosomal dominant pattern, which means that if one parent cat carries the gene responsible for polydactyly, there's a high chance the trait will be passed on to their offspring. In simple terms, if a cat has extra toes, it only needs to inherit the mutated gene from one of its parents to exhibit the condition.

During embryonic development, this mutation affects how the toes form, leading to the creation of extra toes beyond the usual number. This mutation occurs early in the developmental stages, and while it causes an increase in the number of toes, it doesn't negatively affect the cat's overall health or well-being.

Interestingly, what causes polydactyly in cats isn't restricted to one specific breed. While it's more commonly observed in certain breeds like the Maine Coon, any cat can carry the gene for polydactyly. Moreover, this trait is more frequently seen in cats on the East Coast of North America and parts of the UK, possibly because of how the gene spread among cat populations over time.

Famous Polydactyl Cats

Polydactyl cats have not only charmed sailors and cat lovers but have also made their mark in history. One of the most famous examples is the group of cats owned by the celebrated American author Ernest Hemingway. Hemingway was gifted a polydactyl cat by a ship captain, and over time, his home in Key West became a sanctuary for these unique felines. Today, the descendants of those cats still live at the Ernest Hemingway Home and Museum, where visitors can see these "thumb cats" roaming the property.

These famous Polydactyl Cats are often called "Hemingway cats" in his honor, and they've become a symbol of the author's love for animals. The enduring popularity of these cats showcases how their distinctive paws have fascinated people for generations. Whether it's their unusual appearance or the folklore surrounding them, cats with thumbs have certainly earned their place in history and the hearts of cat lovers everywhere.

How to Care for a Polydactyl Cat

Caring for a cat with thumbs isn't much different from caring for any other cat, but there are a few extra considerations when it comes to those extra toes. First, it's important to regularly check and trim the nails on your cat's extra toes. Sometimes these additional digits can make it harder for cats to naturally wear down their nails, which may lead to overgrowth or discomfort. Regular nail maintenance can help prevent any potential issues.

Another thing to watch for is any signs of irritation or infection around the extra toes, particularly if the nails grow in an unusual direction or are prone to becoming caught on things. While most Polydactyl Cats live happy, healthy lives without any complications, it's always a good idea to keep an eye on their feet, just as you would with any other part of their health. If you ever notice swelling, limping, or other signs of discomfort, a quick visit to the vet can help.

Schedule a Check-Up for Your Cat
