What Medical Issues Cause Abnormal Claw-Biting in Cats?

As with any person or animal, medical issues come in a variety of forms.

With any medical issue, it’s best to let a vet advise on the best course of action. But it is worth knowing the possibilities.

From infections to pre-existing conditions, your cat may be suffering from one of the below:

Pemphigus is an autoimmune disease that affects a cat’s skin. It is classified into five different subtypes. Pemphigus foliaceus is the type most commonly associated with cats.

Pemphigus

It manifests as irritation in sensitive areas like the face (eyelids, nostrils, ears), genital area, and yes, the paws. Lesions appear on the beds of the toenails, forming painful crusty areas.

Feline dermatophytosis is a relatively common skin disorder. Despite its common name, it’s got nothing to do with worms. It’s a fungal infection picked up from soil.

Ringworm

In many cases, the fungi are disposed of through routine grooming. But when the fungus takes hold, it will affect hair and nails – substances rich in keratin.

The fungus may also infect and inflame the skin. Untreated ringworm causes hair loss, scales, infected claws, and nails,  which results in excessive grooming.
