Why Does My Cat Have Hairballs Every Week? Causes and What to Do

You love your cat, but you do not love stepping on a wet hairball at 3 AM. If this happens every single week, you are probably wondering: is this normal? The short answer is no. While the occasional hairball (once or twice a month) can be expected from a healthy cat, weekly hairballs are a sign that something is off. It could be their diet, grooming habits, or even an underlying health issue. Let us walk through the most common reasons and what you can actually do about it.

1. Your Cat Is Shedding More Than Usual

Hairballs form when your cat swallows loose fur during grooming. If your cat is shedding a lot, they swallow more fur, which means more hairballs. Seasonal shedding is normal, but indoor cats can shed year-round due to artificial lighting and heating. Regular brushing is your first line of defense. Use a deshedding tool or a rubber grooming mitt to remove loose fur before your cat swallows it. If your cat hates being brushed, try a calming collar to help them relax during grooming sessions. Less loose fur in their stomach means fewer hairballs.

2. Their Diet Lacks Enough Fiber or Moisture

A cat’s digestive system is designed to move fur through the intestines and out in the stool. When the diet is low in fiber or moisture, the fur gets stuck and forms a hairball. Dry kibble alone can be dehydrating and low in fiber. Consider switching to a high-moisture diet like canned food, or add a fiber supplement like pumpkin puree (plain, not pie filling). You can also look into a probiotic supplement to support healthy digestion and regular bowel movements. When fur passes through easily, it does not have a chance to clump into a hairball.

3. Eating Position Could Be Causing Regurgitation

Believe it or not, how your cat eats can affect hairballs. Cats who eat from bowls placed directly on the floor often gulp air along with their food. This can cause regurgitation, which brings up hairballs more frequently. Elevated bowls allow your cat to eat in a more natural, upright posture, reducing air intake and helping food (and fur) move down the right way. Check out our guide on elevated cat bowls to see if a simple change could cut down on those weekly messes.

4. Underlying Health Issues Like Inflammatory Bowel Disease or Motility Problems

If you have addressed grooming, diet, and bowl position but your cat still has weekly hairballs, it is time to think about their gut health. Conditions like inflammatory bowel disease (IBD), pancreatitis, or slow gastrointestinal motility can prevent fur from moving through the digestive tract. These conditions are more common in middle-aged and older cats. A cat that vomits hairballs frequently might actually be vomiting due to nausea, and the hairball is just along for the ride. If your cat is also losing weight, has a dull coat, or seems lethargic, please see your veterinarian. They can run tests to rule out these issues.

5. Long-Haired Breeds and Over-Grooming Due to Stress

Long-haired cats like Persians, Maine Coons, and Ragdolls are naturally prone to more hairballs because their fur is longer and easier to swallow. But even short-haired cats can develop weekly hairballs if they are over-grooming due to stress, allergies, or skin irritation. Stress grooming is a common coping mechanism. If your cat is licking themselves bald or has patches of missing fur, stress might be the root cause. Enrichment, playtime, and a consistent routine can help. Some cats also benefit from a calming collar to reduce anxiety-driven grooming.

6. When to Worry and What to Do Next

Occasional hairballs are not an emergency, but weekly hairballs deserve attention. Here is a simple action plan: brush your cat daily, switch to a high-moisture diet with added fiber, use elevated bowls, and consider a probiotic. If after two weeks you still see weekly hairballs, book a vet visit. Your vet may recommend a hairball-control diet, a laxative gel, or further testing. Never try to pull a hairball out of your cat’s throat, and never give human hairball remedies. If your cat is gagging but not producing a hairball, or if they seem distressed, go to the vet immediately.

“A hairball every week is not a badge of cat ownership, it is a clue that something needs to change.”

Your cat is not doing this to annoy you. Their body is telling you that fur is not moving through the way it should. With a few adjustments to their care routine, you can reduce hairballs to a rare event and keep your cat healthier and happier. And remember, if you ever feel stuck, your vet is your best partner in solving this messy mystery.
