That means that they have extra toes. Cats normally have five toes in the front and four in the back; according to the Hemingway House and Museum website, “about half of the cats at the museum have the physical polydactyl trait but they all carry the polydactyl gene in their DNA, which means that the ones that have four and five toes can still mother or father six-toed kittens. Most cats have extra toes on their front feet and sometimes on their back feet as well. Sometimes it looks as if they are wearing mittens because they appear to have a thumb on their paw.”
