Polydactyl Maine Coons: The Charm of the ‘Hemingway Cat’#

Look at a standard Maine Coon paw. It’s huge. Now add two extra toes. That is a Polydactyl Maine Coon.

Historically, up to 40% of the original Maine Coons in New England were polydactyls. Sailors considered them good luck (and better mousers) on ships because their massive, mitten-like paws gave them better grip on wet decks.

Today, “Polys” are having a renaissance. They are not a separate breed, but a specific genetic variation that makes them look like they are wearing boxing gloves.

What is Polydactyly?#

It comes from the Greek polys (many) and daktylos (finger).

The Gene: It is a simple dominant gene (Pd). If one parent has it, 50% of the kittens will likely have it.
The Look: Usually, a cat has 5 toes on the front and 4 on the back. A Poly can have 6, 7, or even 8 toes.
The Thumb: The most common form creates a “thumb” that sticks out, making the cat look like it’s wearing mittens.

Do They Use the Thumbs?#

Yes. Atticus is not a Poly, but I have visited catteries full of them. They use those thumbs to grab toys, open latches, and steal food with terrifying dexterity. They are the climbers of the cat world.

Are There Health Risks?#

Generally, no. It is a cosmetic trait.

The One Risk: Ingrown Claws. Because the extra toes sometimes sit at weird angles, the claws might not wear down naturally on a scratching post.
Maintenance: You must check their “thumbs” weekly. You might need to trim the claws more often to prevent them from curling into the paw pad.

Show Status#

TICA: Accepts Polydactyls in championship shows.
CFA: Historically disqualified them, but rules are slowly changing.
The Price: Breeders often charge slightly more ($200-$400 extra) for a Poly kitten because they are in high demand.

Conclusion#

If you want a cat that looks like it’s wearing winter mittens and can probably open your treat jar one-handed, get a Poly. They are a living piece of the breed’s nautical history.
