Nibbling Its Own Claws
Grooming & Claw Care
Your cat lifts a paw to its mouth and gently gnaws or tugs at its claws, one toe at a time, often during a longer grooming session.
The Behaviour Behind It
What looks like nail-biting is actually a normal and important part of claw maintenance. A cat's claws grow in layers, and the outer sheath is shed periodically to reveal a fresh, sharp point underneath. Nibbling and pulling at the claws with the teeth helps ease off those loose outer husks — you may even find the little curved shells around the house.
It doubles as ordinary grooming. Cats are meticulous about their paws, using teeth and tongue to work out trapped dirt, bits of litter or debris caught between the toes. A relaxed cat chewing calmly at its claws after a wash is simply keeping its most important hunting and climbing tools in good order.
What You Can Do
Usually nothing — it is self-care and a sign of a cat comfortable enough to groom fully. You can support healthy claws by providing good scratching surfaces, which also help shed the outer sheaths, and by keeping an eye on older cats whose thicker claws may need occasional trimming. If you spot the behaviour, it is a nice moment to check the paws are clean and the claws are not overgrown.

Seen in most cats as part of routine grooming, often after using a scratching post or during a thorough wash. More noticeable in older or less flexible cats whose claws thicken and shed less easily.
