Polydactyl Cats: The Fascinating World of ‘Mitten-Pawed’ Felines
From their unique, mitten-like paws to their storied place in folklore and literary history, polydactyl cats have captivated pet lovers worldwide. These special cats are defined by their extra toesâsometimes one, sometimes as many as three per pawâgiving them a look and charm as distinctive as their DNA. This in-depth guide explores the genetics, types, cultural associations, and care of polydactyl cats, revealing why these multi-toed felines stand out from their four-pawed peers.
What Is Polydactylism?
Polydactylismâsometimes written as polydactylyârefers to the congenital condition where a cat is born with more toes than usual. The name derives from the Greek words “poly” (many) and “dactylos” (fingers or toes). Typically, a cat has 18 toes in total: five on each front paw (including the small, thumb-like dewclaw) and four on each back paw. Any cat boasting more than this is considered polydactyl .
- Normal Toe Count: 18 (5 front, 4 back per paw)
- Polydactyl Toe Count: Can be 1â3 extra on each paw, sometimes leading to a total of 28
- Most Common: Extra toes on the front paws, but some have extras on all four
Genetically, polydactylism results from an autosomal dominant mutation, meaning it is easily passed from parent cats to their kittens. While most polydactyl cats look and behave no differently than their regular-toed relatives, their mitten-like appendages have netted them various nicknamesâfrom “mitten cats” to “thumb cats” to “Hemingway cats” .
Types of Polydactyl Cats
Not all extra toes are created equal! Experts generally recognize three primary types of polydactyly in cats, distinguished by the position of the extra digits :
- Preaxial Polydactyly: Most common. The extra toe appears on the thumb side (inside) of the paw. These often look like an extra dewclaw or even an opposable thumb.
- Postaxial Polydactyly: The extra toe forms on the outer (pinky) side of the paw.
- Mesoaxial Polydactyly: Rare. The additional toe is located between other toes in the center of the paw.
Most polydactyl cats have matching numbers of extra toes on both front paws, though occasionally, a cat may have more on one side or even on the back feet. About 10% of polydactyl cats have more toes on their back paws than their front paws .
Polydactylism in Cat Breeds
Though polydactyly is not limited by breed, certain typesâsuch as the Maine Coonâare genetically predisposed to extra toes. Maine Coons, in particular, show a range of polydactyl phenotypes, with some cats sporting symmetrical extra digits on all four paws, while others exhibit incomplete or fused extra digits .
- Maine Coon: Historically, as many as 40% of Maine Coons on the U.S. East Coast were polydactyl. Today, breeders sometimes preserve this trait.
- Other Breeds: Polydactyly can occur in any breed or domestic cat, and there is no breed where it is considered a defect or disqualification .

The Cat Worldâs Toe Champion: Guinness Record Holders
The record for the most toes on a cat is an impressive 28. First set by a Canadian cat named Jake, and later matched by Paws, a Minnesota cat with three extra digits on each forepaw and one extra per hind paw. These world record-holding cats are often celebrated for their unique, foot-forward feats .

History & Famous Polydactyl Cats: The Hemingway Connection
Few cats are as wrapped in legend as the so-called Hemingway cats. The American author Ernest Hemingway became forever linked to these special felines after he received a six-toed cat named Snow White from a shipâs captain in the 1930s, while living in Key West, Florida. Today, dozens of Snow Whiteâs descendantsâall polydactylâroam Hemingwayâs former estate, now a museum .
- Key West Tradition: Many cats on the island still display the polydactyl trait.
- Seafaring Origins: Sailors prized polydactyl cats for purported extra balance and ability to catch mice on ships. Folklore suggests these cats brought luck and kept vermin under control.
Beyond Hemingway, polydactyl cats are woven into maritime history. British and American sailors actively sought these cats for ships, believing their unique paws gave them stronger sea legs and hunting skills.
Personality & Physical Traits of Polydactyl Cats
Polydactyly only impacts the structure of a catâs paws and does not affect their personality or other body features. Just like any other cat, polydactyls showcase the full spectrum of feline personalities and come in every size, shape, and coat color .
- No adverse health effects: Polydactylism is a harmless genetic condition and has no bearing on a catâs overall health or wellbeing.
- Functionality: Most polydactyl cats use their extra toes adeptly, sometimes even learning to open doors or grasp small objects like toys.
- Unique appearance: Their broad, rounded paws are undeniably cute and are particularly photogenic.
Folklore, Myths, and Cultural Associations
Thanks to their eye-catching paws and long history, polydactyl cats are cloaked in myth:
- Good Luck: Sailors believed these cats brought good fortune and safe passage at sea.
- Feline Superstitions: Some believed the extra toes allowed cats to hunt more efficiently; others thought it made them more magical or closer to humans.
- Hemingwayâs Curse or Gift: In Key West, some still claim that the proliferation of polydactyl cats signals Hemingwayâs enduring influence or even a genial haunting.
Whatâs it Like Living With a Polydactyl Cat?
Caring for a polydactyl cat is much like caring for any other feline, with a few practical considerations concerning their extra toes:
- Nail Care: More toes mean more claws to trim. Itâs important to monitor all digits, as extra toes may be prone to ingrown nails or other issues.
- Paw Health: Rarely, an abnormal extra digit can become injured or infected, particularly if it doesnât touch the ground or is malformed.
- Litter Box: Extra toes may collect additional litter, so keep an eye on paw cleanliness.
- Mobility: Most polydactyl cats are just as agile (or more so!) than their regular-toed counterparts.
If you adopt a polydactyl cat, be prepared for compliments, curiosity, and a remarkable conversation starter anywhere you go!
Polydactyl Genetics: How is the Trait Inherited?
Polydactylism is caused by a dominant gene mutation. This means only one parent needs to carry the gene for the trait to be passed to offspring .
- Dominant inheritance: If one cat parent is polydactyl, approximately half of its kittens will be as well.
- Full spectrum: Extra toes may appear on front, hind, or all paws, but front-paw-only polydactyly is most frequent.
The trait does not skip generations, and its expression may varyâfrom subtle extra digits to fully formed “thumbs.”
Polydactyly Vs. Other Feline Digit Conditions
Itâs important to distinguish polydactylism from other, less benign conditions:
- Polydactylism: Harmless, genetic, and purely about extra toes.
- Syndactyly: A rare deformity where two or more toes are fused. This is a structural anomaly but not the same as having extra digits.
- Injury or Disease: Trauma or developmental issues can sometimes lead to abnormal paw growth but are unrelated to genetic polydactylism.
Should You Adopt a Polydactyl Cat?
If youâre considering adoption, know that polydactyl cats make loving and healthy companions. They donât require any special food or medical care, just the standard routine vet checks and grooming (with a little extra attention paid to their adorable paws).
Many animal shelters have polydactyls, so if youâre hoping to meet one of these marvels, ask your local adoption organizations or breed-specific rescues.
Frequently Asked Questions (FAQs)
Q: Are polydactyl cats a specific breed?
A: No, polydactylism is a genetic trait found across many breeds and mixed-breed cats. It is most famously associated with Maine Coons and the cats of Hemingway House, but it can show up in any feline lineage.
Q: Do extra toes cause health problems?
A: In the overwhelming majority of cases, no. Polydactyl cats live normal, healthy lives. Problems only arise if an extra toe is malformed or prone to catching on carpets and objects, in which case a vet can advise on care or removal.
Q: Are polydactyl cats more agile than other cats?
A: Sailors used to think so, and many pet owners report their polydactyl cats are exceptional climbers and hunters. However, studies show there is no consistent evidence that extra toes confer greater agility.
Q: How often should I trim my polydactyl catâs claws?
A: Check and trim all toesâespecially the extrasâabout every 2â4 weeks. Make sure to monitor for ingrown or misshapen nails among the extra digits.
Q: Are polydactyl cats rare?
A: They are not exactly common, but neither are they exceedingly rare. It depends on the local cat population and whether polydactyl genes are present in your area. In certain regions (like parts of New England, U.K., and Florida Keys), they are more frequently found.
If youâve been enchanted by the sight of a cat with an extra thumb or mitten paw, know that youâre beholding a living piece of feline historyâone with roots stretching from ancient seafaring superstition to the literary gardens of Ernest Hemingway. While their unique paws may attract first glances, itâs the loving nature of polydactyl cats that win hearts for a lifetime.
