Understanding the Value of Polydactyl Cats
Polydactyl cats, commonly referred to as
mitten cats or
Hemingway cats, are felines born with more toes than the average cat. While most cats have
18 toes—five on each front paw and four on each hind paw—polydactyl cats can have up to seven toes per paw, with some exceptional cases featuring a total of
28 toes.
What Causes Polydactyly?
The condition is caused by a
dominant genetic mutation, often passed from just one parent. This gene mutation affects the development of limbs and results in the growth of extra digits. While the additional toes can appear on any paw, they are most commonly found on the
front paws. There are three main types of polydactyl formations:
- Preaxial: Extra toes on the inner (thumb) side of the paw
- Postaxial: Extra toes on the outer (pinky) side
- Mesoaxial: Extra toes in the middle of the paw
Are Polydactyl Cats Rare?
Despite popular belief, they are
not rare. In certain regions like
Massachusetts,
Key West, Florida, and parts of
Canada and the UK, the trait is relatively common. Breeds such as the
Maine Coon and
Pixiebob are more likely to exhibit polydactyly, and nearly 40% of early Maine Coons reportedly had the trait.
How Much Is a Polydactyl Cat Worth?
Financially, polydactyl cats don't carry significantly more value than regular cats. Their economic worth is usually
similar to that of any domestic cat, unless they are part of a rare breed or have a certified pedigree. Factors that might increase a polydactyl cat's value include:
- Association with a recognized breed, like a pedigree Maine Coon
- Show-quality physical characteristics
- Unique cultural or historical significance (e.g., descendants from Hemingway’s cats)
Generally, prices can range anywhere from
$50 to $500, depending more on breed and health than on the number of toes.
Health and Maintenance Considerations
Extra toes do not usually lead to health issues. However, some polydactyl cats may have digits that are
poorly attached to underlying bones, which can make them more prone to injury. Additionally, their
extra claws can grow incorrectly or inward, causing discomfort or infection.
To ensure polydactyl cats stay healthy, owners should:
- Trim nails regularly, including those on extra toes
- Check paws for swelling, redness, or dirt
- Consult a vet if mobility issues or infections arise
Historical Significance and Popularity
Polydactyl cats have long been favored by sailors, who believed that broader paws helped cats balance on ship decks. They were also considered
good luck onboard. The American writer
Ernest Hemingway popularized the term "Hemingway cat" after receiving one from a sea captain. Today, his former home in Key West is inhabited by dozens of his polydactyl cats' descendants.
Genetic Insights
The trait is commonly associated with mutations in the
ZRS regulatory region that influences the
sonic hedgehog (SHH) gene—important in limb development. Various mutations can cause mild to extensive toe proliferation.
Conclusion
Polydactyl cats are often admired for their quirky appearance and rich cultural history. While they may not be especially valuable in terms of money, their uniqueness and connection to beloved human traditions make them
emotionally priceless. Unless part of a rare breed, these cats are available at typical pet adoption fees, making them a great find for cat lovers who enjoy a little extra toe action!
