It’s a quiet Tuesday night. You’re sitting on the couch, and suddenly you hear it—that rhythmic, wet thwip-thwip-thwip of your cat grooming. But it sounds different this time. More intense. You look over and realize she isn't just cleaning herself; she’s literally yanking out tufts of fur with her teeth.
Panic sets in. You see a bald patch on her belly or a "racing stripe" down her spine where the skin looks angry and pink. "Why is my cat pulling her hair out?" you ask the empty room. Honestly, it's one of the most frustrating things a pet owner can deal with because the list of culprits is a mile long.
It’s not just about vanity or a messy carpet. When a cat starts self-mutilating their coat, they are screaming—metaphorically—that something is wrong. It could be a physical itch they can't scratch, or it could be a psychological "short circuit" caused by the new neighbor’s dog or even a change in your work schedule.
The Itch That Won't Quit: Medical Triggers
Before you assume your cat has "anxiety," we have to talk about biology. Cats are incredibly stoic. They don't moan or complain; they lick.
Flea Allergy Dermatitis (FAD) is the heavyweight champion of hair loss. You might think, "My cat doesn't have fleas; I haven't seen any." That doesn't matter. For a cat with FAD, a single bite from a solitary flea can trigger a massive inflammatory response. The saliva of the flea is the allergen. It makes them feel like they are crawling out of their own skin. They chew and pull at the base of the tail and the back of the legs because that's where the hitchhikers usually hang out.
Then there’s the food. Just like humans can’t handle peanuts or dairy, some cats develop a hypersensitivity to specific proteins. It’s usually the stuff they eat most often, like chicken or beef. This isn't a "tummy ache" situation; it manifests as itchy skin, mostly around the head and neck. They scratch and pull until they bleed.

Environmental Allergies and Fungi
Don't rule out the world around them. Dust mites, pollen, and even certain cleaning chemicals can cause atopic dermatitis. If you recently switched your floor cleaner or bought a new scented candle, pay attention.
And then there's Ringworm. Despite the name, it’s a fungus, not a worm. It’s highly contagious—even to you. It typically creates circular bald spots, and while some cats don't find it itchy, others will pull their hair out trying to get rid of the crusty sensation.
When the Brain Takes Over: Psychogenic Alopecia
If the vet clears her of bugs and rashes, you’re likely looking at psychogenic alopecia. This is basically the feline version of Obsessive-Compulsive Disorder (OCD).
Cats love routine. They crave it. When their environment becomes unpredictable, they look for ways to soothe themselves. Grooming releases endorphins in a cat’s brain. It feels good. It’s calming. But sometimes, they get "stuck" in that feedback loop. The grooming becomes a compulsive behavior used to cope with stress.
What stresses a cat out?

- A new baby or a new roommate.
- Moving furniture around (seriously).
- Seeing a stray cat through the window.
- Boredom. Yes, a bored cat is a destructive cat.
Imagine being trapped in a studio apartment with nothing to do all day. You might start biting your nails. Your cat pulls her hair.
The Hidden Pain Factor
This is the one people usually miss. Sometimes, why is my cat pulling her hair out has nothing to do with the skin at all. It’s about what’s underneath.
Cats will often over-groom the area directly above a source of pain. If a cat has a urinary tract infection (UTI) or bladder stones, they might lick their lower abdomen until it's bald because the referred pain is localized there. Similarly, a cat with arthritis in her hips might chew at the fur on her joints.
It’s a distraction technique. The sensation of licking or pulling masks the deep, dull ache of the internal issue. If you see your cat focusing on one very specific spot—like a joint or the lower belly—instead of general thinning all over, get an X-ray or a urinalysis. Don't just buy a new brush and hope for the best.
Breaking the Cycle: What to Do Next
You can't just tell a cat to stop. That's not how it works. You have to be a detective.

First, the "Flea Test." Even if you don't see bugs, use a flea comb. Look for "flea dirt"—tiny black specks that turn red when placed on a wet paper towel. If you find that, you have your answer. Start a high-quality, vet-approved monthly preventative.
Second, look at the "Stress Map" of your home. Has anything changed in the last three months? If the answer is yes, try to reintroduce stability. Feliway (synthetic pheromones) can help take the edge off. It mimics the "happy markers" cats leave when they rub their cheeks on things.
Dietary Trials
If your vet suspects a food allergy, you'll need to do an elimination diet. This means feeding a "novel protein" like rabbit, venison, or hydrolyzed protein for 8 to 12 weeks. No treats. No scraps. No "just this once." It’s a commitment, but it’s the only way to rule out food as the trigger.
Actionable Steps for a Balding Cat
Don't wait until she’s completely naked. The skin is the body's largest organ, and once it's compromised, infections move in fast.
- Schedule a Vet Visit Immediately: Ask specifically for a skin scraping (to check for mites) and a fungal culture. Mention if she’s been straining in the litter box, as this points to pain-related pulling.
- Mechanical Barriers: While you find the cause, use a "cone of shame" or a soft recovery suit. It feels mean, but it stops the self-trauma and allows the skin to heal.
- Environmental Enrichment: If it’s stress or boredom, "catify" your space. Vertical climbing spots, window perches, and puzzle feeders can redirect that nervous energy into something productive.
- Check Your Cleaners: Switch to unscented, pet-safe laundry detergents and floor cleaners. Sometimes the simplest change is the most effective.
- Medication: In severe cases of psychogenic alopecia, your vet might prescribe fluoxetine or clomipramine. There is no shame in "kitty Prozac" if it prevents her from hurting herself.
The road to regrowth is slow. Hair takes weeks to grow back, and the habit of pulling is hard to break once it's ingrained. Be patient. Watch for the tiny "stubble" that indicates the pulling has stopped, and keep a log of when she does it most. Is it right after you leave for work? Right after dinner? That data is gold for your vet.
Stop the itch, soothe the mind, and the fur will follow.
