Have you ever noticed a cat with more toes than usual? These special felines, known as polydactyl cats, are born with a genetic mutation that gives them extra digits. While most cats have 18 toes—five on their front paws and four on their back paws—polydactyl cats can have as many as eight on a single paw!

What Causes Polydactyl Cats?

The condition, known as polydactyly, is caused by a genetic mutation in the dominant gene responsible for toe development. This means that if one parent carries the gene, there’s a good chance their kittens will inherit the trait. Polydactyly doesn’t cause harm or health problems for cats, making it a harmless and fascinating feature.

A Rich History of Extra-Toed Cats

Polydactyl cats have a storied history, particularly among sailors. In the past, these cats were prized as ship companions, as their extra toes were believed to give them better balance on rough seas. They also earned the nickname “Hemingway cats” after author Ernest Hemingway, who famously kept a colony of polydactyl cats at his home in Key West.

Does Polydactyly Affect a Cat’s Health?

Thankfully, having extra toes doesn’t typically impact a cat’s health or mobility. In fact, many polydactyl cats use their extra digits to their advantage, gripping objects or climbing with ease. However, owners should pay attention to their cats’ extra toes during grooming, as they may need help keeping them clean or trimming their nails.

Is Polydactyly Common?

Polydactyl cats are more common in certain regions, especially in North America and parts of England and Wales. Some breeds, like the Maine Coon, are more likely to have the mutation due to selective breeding. These cats often capture attention with their adorable oversized paws, known as “mitten paws” or “snowshoe feet.”
