Why do some cats have extra toes?
A polydactyl cat is born with more than the usual number of toes because of an inherited developmental variation. Many extra toes cause no difficulty, but every claw must be found and monitored because unusual positions may prevent normal wear.

✓ Polydactyl cats are born with more than the usual number of toes because of an inherited developmental variation.
✓ Count and inspect every claw regularly because hidden claws can overgrow into pads.
✓ Limping, swelling or an embedded claw requires veterinary treatment.
Polydactyl cats are born with more than the usual number of toes because of an inherited developmental variation. Extra toes can be harmless, but unusual claw positions may need extra monitoring. Here is the useful version of the answer: how it works, what to monitor and when a physical change deserves veterinary attention.
How extra toes develop
Limb formation is guided by signalling during early development. Certain inherited variants change the toe pattern, producing extra digits most often on the front paws, although the number and arrangement differ between cats.
What to notice
Some extra toes are well aligned and functional; others are small, angled or closely spaced. Count toes and claws on every paw while the cat is relaxed, including hidden claws that may not touch a scratcher or the ground.
What to do at home
Inspect each claw regularly and trim only the clear hooked tip when needed. Provide stable scratchers and non-slip surfaces. Ask a veterinary professional to demonstrate safe trimming if the claw direction or quick is difficult to see.
What this does not prove
Polydactyly does not automatically cause pain or make a cat a better climber. Toe number alone says little about health or personality. Welfare depends on the structure, movement and maintenance needs of the individual paw.
When to contact a veterinarian
An embedded or twisted claw, repeated snagging, swelling, bleeding, pain, persistent licking or limping needs veterinary care. Do not pull a caught claw or cut near the quick.

Three simple things you can do
You do not have to change everything today. Pick one step that feels realistic, try it and see how your cat responds.
- 1Count every toe and claw while the cat is relaxed, including small or unusually positioned claws.
- 2Inspect and trim each claw on an individual schedule because some extras do not wear normally.
- 3Ask a veterinarian to check twisting, pad contact, recurrent snagging, swelling or altered walking.
Common mistakes
×Assuming every extra claw wears down on a scratcher.
×Missing a hidden claw until it curls into the pad.
×Breeding solely for more extreme toe numbers without prioritising structure and welfare.
Questions cat people ask
What is a polydactyl cat?+
A polydactyl cat is born with more than the usual number of toes because of an inherited developmental variation. Many live comfortably with routine claw monitoring.
Do extra toes cause health problems?+
Not automatically. Risk depends on their structure and claw position; embedded claws, repeated snagging, pain, swelling or limping require veterinary care.

A cat with two differently coloured irises has complete heterochromia, usually because the eyes contain different amounts or distributions of pigment. A lifelong difference can be normal; a newly changing eye colour is a medical sign.
