Cats rub their bum on the carpet, a behavior vets call “scooting,” because something around their rear end is irritating them. The most common culprits are impacted anal glands, intestinal parasites, or allergies causing itchy skin. While it can look funny, scooting is almost always a sign of discomfort, and figuring out the specific cause matters because some require veterinary treatment.
Anal Gland Problems
Cats have two small sacs just inside the anus that produce a strong-smelling fluid. Normally, this fluid gets squeezed out naturally every time your cat has a bowel movement. When the sacs don’t empty properly, the fluid thickens and builds up, creating pressure and irritation. Your cat scoots on the carpet trying to relieve that pressure manually.
Anal gland disease is far less common in cats than in dogs. A cross-sectional veterinary study estimated the incidence at only about 0.4% in cats, compared to nearly 16% in dogs. But when it does happen, it follows the same progression: impaction leads to bacterial overgrowth, which can cause infection and inflammation. If the duct becomes completely blocked while infected, an abscess can form. A ruptured abscess appears as an open, draining wound near the anus and needs prompt veterinary care.
Beyond scooting, cats with anal gland trouble often lick or bite at the area obsessively, strain during bowel movements, or seem reluctant to sit down. You might also notice a particularly foul smell that goes beyond normal litter box odor. Overweight cats are more prone to this problem because reduced muscle tone around the rear makes it harder for the glands to empty on their own.
Tapeworms and Other Parasites
Tapeworms are a very common reason for scooting, especially in cats that hunt or have had fleas. The most typical species, picked up through flea ingestion, sheds small segments called proglottids that crawl out of the anus. These segments look like grains of rice or small seeds and can sometimes be spotted near your cat’s rear end or on the surface of fresh stool. As they move, they cause intense itching, and your cat drags its bottom across the carpet to scratch an itch it can’t reach any other way.
One tricky thing about tapeworms: a standard fecal exam at the vet often won’t detect them. The CDC notes that vets typically rely on pet owners noticing the segments themselves rather than finding eggs under a microscope. So if your cat is scooting and you see tiny white or yellowish flecks around the litter box or stuck to fur near the tail, that’s a strong clue to bring up at your vet visit.
Food Allergies and Skin Irritation
Allergies can cause itching virtually anywhere on a cat’s body, including around the rear. Food allergies in particular trigger widespread itchiness that shows up as scratching, rubbing, or pulling out fur. The most common food triggers in cats are beef, fish, and chicken. While allergic itching in cats tends to concentrate around the face, ears, and neck, it can also affect the belly, paws, or spread more generally, which sometimes includes the perianal area.
If your cat scoots but has no signs of worms and the anal glands check out fine, allergies become a more likely explanation. Other clues include patches of thinning fur from over-grooming, small crusty bumps scattered across the skin (called miliary dermatitis), or raised sores on the lips or body. Identifying a food allergy usually involves feeding an elimination diet for several weeks under veterinary guidance to pinpoint the trigger ingredient.
Other Possible Causes
Sometimes the explanation is simpler. A piece of dried stool stuck to the fur around the anus, especially in long-haired cats, can cause enough irritation to trigger scooting. Diarrhea or soft stool can also leave the skin around the rear raw and uncomfortable. In rarer cases, growths or injuries near the anus may be responsible. If scooting happens once and never again, a minor irritation was likely the cause. Repeated scooting over days points to something that needs investigation.
What Happens at the Vet
A vet will typically start with a physical exam of the anal area, checking whether the glands feel full or swollen. If they’re impacted, the vet can manually express them, squeezing out the built-up fluid. This is a quick procedure, though it can be uncomfortable enough that some cats need mild sedation. If there’s an active infection, the vet may flush the sac with a cleaning solution and apply medication directly into it. Abscesses that haven’t drained on their own need to be opened and cleaned, followed by a course of antibiotics and pain relief.
For parasites, treatment is straightforward once identified: a deworming medication clears the infection, and flea prevention helps stop reinfection.
Preventing Repeat Episodes
Diet plays a bigger role than most owners realize. Modern commercial cat foods are designed for palatability and high digestibility, which often means less fiber and smaller, softer stools. The problem is that firm, bulky stool is exactly what naturally presses against the anal glands during a bowel movement, keeping them emptied. When stool is too soft, the glands don’t get that mechanical squeeze.
Adding fiber to your cat’s diet can help. Pumpkin (plain, not pie filling) is a common recommendation because it adds bulk without upsetting digestion. Some fiber supplements designed for pets combine soluble and insoluble fiber sources like pumpkin seed and apple pectin to promote firmer stools. For cats with recurring anal gland issues, periodic manual expression at the vet, sometimes every few weeks, can prevent buildup between visits.
Keeping your cat at a healthy weight also matters. Excess body fat reduces muscle tone around the rear and makes natural gland expression less effective. And staying current on flea prevention eliminates the main route cats pick up tapeworms, cutting off that cause of scooting before it starts.
