7 Things to Know About Polydactyl Cats

Most cats have a total of 18 toes — five on each of their front feet and four on each of the back. But some felines are born with extra toes. Those kitties are polydactyl, a Greek term meaning many digits or toes.

Since polydactyl cats are so fascinating and cool looking, we paired fun facts about polydactylism with adorable photos of our readers' extra-toed kitties. Check out the photo gallery below to learn more.

Fact No. 1: They're also known as Hemingway cats.

You may have heard polydactyls called “Hemingway cats,” a reference to the legendary American writer Ernest Hemingway, who preferred polydactyl cats. His first cat, Snowball, had six toes, and today, about 50 of the cat’s descendants still live on Hemingway’s historic property in Key West.

Fact No. 2: They've been around a long time.

The first record of cats like Snowball is from 1868, and they were mostly found in the Northeastern U.S. and Nova Scotia. Polydactyl cats were often found on ships because sailors believed they were good luck and thought the extra toes gave them better balance while on the high seas.

Fact No. 3: It's sometimes genetic.

Some cats have extra toes because they inherit a gene that codes for polydactylism. According to veterinarian Dr. Arnold Plotnick of Manhattan Cat Specialists in New York, if one parent is polydactyl and the other has normal feet, 40 to 50 percent of the kittens will also have extra toes.

Fact No. 4: Sometimes they look like they have thumbs.

Most polydactyl cats have toes that look like their other toes, just more of them. But in some cats, the dewclaw is so big that it looks like a thumb. They're known as thumb cat polydactyls.
