If your cat is licking, chewing, or scratching more than usual — or you’re noticing thin, bald, or raw patches of skin — you’re probably wondering whether this is a bad habit or something more. Here’s how to tell the difference and what to do next.
Excessive grooming can look subtle at first — a thinning patch here, a little extra licking there.
Cats are naturally fastidious groomers, spending a good chunk of their day cleaning themselves. But when grooming crosses the line from routine maintenance into constant licking, chewing, or hair-pulling, it’s called overgrooming — and it’s your cat’s way of telling you something is wrong. Sometimes it’s medical, sometimes it’s stress-related, and sometimes it’s both feeding off each other.
Cats are creatures of routine, and even small disruptions — a new pet, a move, construction noise, a change in your work schedule, or a new piece of furniture — can trigger anxiety. Overgrooming is a self-soothing behavior, similar to nail-biting in humans, and it often shows up as symmetrical hair loss on the belly, inner thighs, or front legs, areas your cat can easily reach while curled up.
If you suspect stress is behind the licking, a calming cat bed or a pheromone diffuser designed to ease anxiety in the home can help take the edge off while you work on identifying the root cause. Check Price on Amazon
Just like people, cats can develop allergies to things in their food (common culprits include beef, dairy, and fish) or in their environment (pollen, dust mites, mold, or even a new laundry detergent). Allergic reactions often cause itchy, inflamed skin, which leads to targeted licking and chewing around the face, ears, paws, or belly. Seasonal patterns are a big clue — if the overgrooming flares up at certain times of year, environmental allergies are worth investigating with your vet.
Even indoor-only cats can pick up fleas, mites, or other parasites, and flea allergy dermatitis is one of the most common causes of intense itching and overgrooming in cats. A single flea bite can trigger a disproportionate reaction in sensitive cats, leading to hair loss around the base of the tail, lower back, and neck. Before assuming the cause is behavioral, it’s worth doing a simple physical check — running a flea comb to rule out parasites is a fast, low-cost way to eliminate this possibility.

Overgrooming isn’t always about the skin’s surface — it can also be a response to pain underneath it. Cats with arthritis, a healing injury, urinary discomfort, or even dental pain will sometimes lick excessively at the area closest to where they hurt. This is one of the reasons repeated licking of one specific spot deserves a vet visit rather than a wait-and-see approach, since it may point to something that isn’t visible from the outside.
Cats that don’t get enough mental or physical stimulation can develop grooming into a compulsive habit, not unlike pacing in other animals. This is more common in indoor-only cats, especially those left alone for long stretches without toys, climbing structures, or interactive play. Once grooming becomes a learned coping mechanism, it can persist even after the original trigger is addressed, which is why enrichment plays such a big role in recovery.
Beyond allergies and pain, a handful of medical issues can drive overgrooming, including hyperthyroidism, ringworm, bacterial or yeast skin infections, and gastrointestinal issues that cause referred abdominal discomfort. These conditions usually come with other symptoms too — weight changes, appetite shifts, vomiting, or changes in coat quality — so it’s worth mentioning any additional changes you’ve noticed when you talk to your vet, even if they seem unrelated to the grooming itself.
Some grooming is completely normal — cats can spend a few hours a day cleaning themselves. The concern starts when grooming becomes so frequent it causes visible hair loss, skin damage, or interferes with normal activities like eating or sleeping.
It’s possible if the trigger is minor and temporary, like a short-lived stressor. But because overgrooming often has a medical root or can become a self-reinforcing habit, it’s best not to assume it will resolve without intervention, especially if it’s been going on for more than a couple of weeks.
Stress-related licking tends to be more symmetrical, affecting easily reachable areas like the belly and inner legs. Medical or pain-related overgrooming is often localized to one spot and may come with redness, scabbing, or a visible wound underneath — a strong signal to see your vet.
Not always on the first visit — sometimes it takes a process of elimination involving skin scrapings, bloodwork, or a food trial to pin down the exact cause. But a vet exam is still the right starting point, since it rules out the most urgent possibilities first.

Overgrooming is your cat’s way of communicating that something isn’t right, whether that’s an itch, an ache, or an anxious mind. It’s rarely something to ignore, but it’s also very manageable once you know the cause — a vet visit to rule out medical issues, paired with some stress reduction and enrichment at home, resolves the majority of cases. Keep an eye on bald patches, sores, or one specific spot getting all the attention, and don’t hesitate to get professional input sooner rather than later.
