Polydactyl cats are unique felines that have more than the usual number of toes on their paws. While most cats have five toes on their front paws and four on their back paws, polydactyl cats can have six or more toes on each paw. This genetic trait is often seen in certain breeds, such as the Maine Coon and American Polydactyl. The extra toes can give these cats a distinctive appearance and may enhance their ability to climb and grasp objects. Polydactylism is caused by a genetic mutation, and these cats are sometimes affectionately referred to as "Hemingway cats," named after the famous author Ernest Hemingway, who owned many polydactyl cats.
