Psychogenic Alopecia (Stress Over-Grooming)

A pattern of hair loss caused not by disease of the skin itself but by over-grooming — a cat licking, chewing or plucking its own fur, usually in response to stress, anxiety or boredom.

⚠️ Common symptoms

Thinning fur or bald patches, often on the belly, inner thighs, flanks or forelegs — areas the cat can easily reachSkin that usually looks otherwise normal and healthy underneathFur that appears stubbly or barbered rather than shed, sometimes with a brownish tinge from salivaIncreased licking, especially in short bursts when stressed or startledMore hairballs than usual from swallowed furA "racing stripe" of hair loss down the back or a bare strip along the tummy

Psychogenic alopecia is hair loss that a cat inflicts on itself through over-grooming, driven by stress, anxiety or boredom rather than by a primary disease of the skin. Cats are fastidious groomers at the best of times, spending a good part of the day washing, but the repetitive action of licking also releases soothing endorphins. For an anxious cat, grooming becomes a way to self-comfort — and when that tips into excess, fur starts to disappear from the areas the cat can most easily reach: the belly, inner thighs, flanks and forelegs.

The tell-tale sign is that the skin underneath usually looks normal and healthy, with the fur barbered short or plucked bare rather than genuinely diseased. Owners often notice a bald strip down the tummy, thinning along the back legs, or an increase in hairballs from all the swallowed fur.

The single most important thing to understand is that psychogenic alopecia is a diagnosis of exclusion. A great many cats that appear to be "stress-grooming" are in fact responding to a physical itch or pain — fleas and flea-allergy dermatitis, mites, ringworm, food or environmental allergies, or discomfort from arthritis or a bladder problem can all provoke exactly the same frantic licking and identical hair loss. For this reason a vet will always look for and rule out medical causes first, using flea treatment trials, skin tests and sometimes diet trials, before attributing the behaviour to anxiety.

Where stress genuinely is the cause, the trigger is often a change the cat has found unsettling: a new cat or person in the home, a house move, ongoing tension with another pet, a disrupted routine, or simple boredom in an unstimulated indoor life. Treatment then focuses on the cause rather than the symptom — enriching the environment with play, height and hiding places, restoring predictable routines, easing multi-cat conflict by providing plenty of separate resources, and using pheromone diffusers to promote calm. In persistent cases a vet may add anti-anxiety medication to support the behavioural changes. The outlook is good: once the underlying itch or stress is addressed, the fur almost always grows back.

🔍 Causes

Over-grooming is a self-soothing behaviour: the repetitive licking releases calming endorphins, so an anxious cat grooms to comfort itself. Common triggers include changes in the household (a new pet, baby, or move), conflict with another cat, boredom in an under-stimulated indoor cat, a disrupted routine, or lack of secure resting places. Crucially, many cases that look psychological turn out to have a physical itch behind them, which is why a medical work-up comes first.

🛡 Prevention

Provide a rich, predictable environment: daily interactive play, climbing and scratching outlets, cosy hiding spots, and food puzzles that occupy the mind. Keep routines steady, introduce new pets or people gradually, and make sure a multi-cat home has enough separate resources — food, water, litter trays and resting places — to avoid competition and tension. Keeping up rigorous flea control removes one of the most common physical triggers.

💊 Treatment

The first and most important step is a vet visit to rule out physical causes of itching — fleas, mites, ringworm, allergies and pain can all drive over-grooming and look identical. Only once medical causes are excluded is it treated as stress-related. Management centres on reducing anxiety: identifying and easing the trigger, enriching the environment, adding vertical space, safe hideaways, predictable routines and plenty of interactive play. Pheromone diffusers can help, and in stubborn cases a vet may prescribe anti-anxiety medication alongside behavioural work.

When to see a vet: See your vet whenever your cat is losing fur or grooming excessively — do not assume it is "just stress", as the appearance is identical to that of fleas, allergies, ringworm and pain. A vet visit is essential to rule these out before a behavioural cause is confirmed, and to guide treatment if anxiety is the root.

Grooming is soothing for cats — but when stress tips it into over-grooming, fur starts to disappear

Barbered, stubbly fur over normal-looking skin is the hallmark of over-grooming rather than skin disease
