Cat Overgrooming: Why Your Cat Licks Bald Spots

Finding bald patches on your cat — especially on the belly, inner thighs, or flanks — is alarming. Overgrooming (psychogenic alopecia) is not a bad habit. It's a symptom. Here are the real causes.

Medical Causes — Rule These Out FIRST

Allergies (Most Common)

Flea allergy, food allergy, or environmental allergies (atopic dermatitis). The cat overgrooms to relieve itching. Flea allergy is #1 — even indoor cats get fleas. One flea bite can trigger weeks of overgrooming in an allergic cat.

Pain

Cats lick painful areas. Bladder pain from FLUTD causes belly overgrooming. Arthritis causes hip/leg overgrooming. Dental pain is sometimes expressed as face rubbing and paw licking.

Skin Infections

Bacterial or fungal (ringworm) causes itching. Ringworm is zoonotic — you can catch it from your cat.

Hyperthyroidism

Excess thyroid hormone can cause skin changes, restlessness, and overgrooming. Senior cats especially.

Behavioral Causes

Stress and Anxiety

Changes in routine, new pet, new baby, moving, construction, owner's work schedule change, or outdoor cats visible through windows. Overgrooming becomes a compulsive self-soothing behavior — like nail-biting in humans. The licking releases endorphins, making it self-reinforcing.

Boredom

Indoor cats without sufficient enrichment may overgroom. This is especially common in single-cat households where the owner is away all day.

Diagnosis

Vet visit first — always rule out medical causes. Steps: check for fleas (even indoor cats), skin scraping or cytology, food elimination diet trial (8-12 weeks), blood work (thyroid, organ function), and in some cases, skin biopsy.

Treatment

Treat the underlying cause (fleas, allergies, pain). Increase environmental enrichment: puzzle feeders, wand toys 2x daily, window perches. Feliway pheromone diffusers. Reduce stress. Never punish the cat — it makes stress and overgrooming worse. In severe behavioral cases, anti-anxiety medication (fluoxetine, clomipramine) from a veterinary behaviorist.

Bald patches are never normal. Find the cause.
