Your cat has six claws because of a genetic condition known as polydactyly.
What is Polydactyly in Cats?
The term polydactyly literally means "many toes." This interesting trait in cats is caused by a genetic trait that occurs in certain felines whose parents passed this trail down through their lineage. It is a dominant gene, meaning that if a cat inherits this gene from even one parent, they are likely to exhibit the condition.
Here's what makes polydactyly unique:
- Genetic Origin: It's purely a result of inherited genetics, not an injury or environmental factor.
- Number of Toes: This dominant gene can produce up to seven toes on each paw, though having six is a common presentation.
- Location: While it is typically seen on the front paws, all four feet can be affected, resulting in a cat having extra toes on multiple or all paws.
- Appearance: The extra toes can sometimes look like a "thumb" (often called "mitten paws" or "Hemingway cats") or simply extra digits lined up with the others.
Polydactyly is generally harmless to the cat and is often seen as a charming characteristic. It doesn't typically impede a cat's ability to walk, run, or climb.
Here's a simple comparison:
| Feature | Normal Cat Paw | Polydactyl Cat Paw |
|---|---|---|
| Toes (Front Paw) | Typically 5 | Often 6 or more |
| Toes (Back Paw) | Typically 4 | Can be 4 or more |
| Cause | Standard genetics | Dominant genetic trait |
If your cat has six claws (meaning they have an extra toe with a claw), they are a charming example of this genetic variation. It's simply how they were born due to the genes inherited from their parents.
