Grooming is a cat's second job. Adult cats spend 30–50% of their waking hours on it, and almost all of it is normal, healthy behavior.

What grooming does

When grooming becomes a problem

A red flag is over-grooming: bald patches, thinning hair, or skin lesions, especially on the belly and inner legs. The two main causes are allergies or parasites (fleas, food allergy) and anxiety or boredom.

See a vet for any bald or inflamed skin. Over-grooming is itchy or stressful — not a discipline problem — and scolding makes it worse.
