Why Does My Cat Keep Throwing Up Hairballs? Causes, Prevention, and Relief

Hairballs are common, but they are not something most cat parents enjoy finding on the rug. If your cat keeps throwing up hairballs, it usually means loose hair is collecting in the digestive tract faster than the body can move it along. Cats groom constantly, so swallowing some fur is normal. Trouble starts when too much hair builds up, especially in long-haired cats, indoor cats, heavy groomers, and cats going through seasonal shedding.

Occasional hairballs may be part of normal grooming. Frequent hairballs are a sign that your cat’s routine may need more support. The goal is to help hair pass more smoothly, reduce buildup, and support overall digestive comfort.

Why cats get hairballs

Hairballs are more likely when a cat sheds heavily, overgrooms, or has a coat that traps loose fur. Long-haired breeds often deal with them more than short-haired cats, but any cat can have the problem. Indoor cats may also groom more out of boredom or habit. In some cases, digestive slowdown, stress, or diet issues may make it harder for swallowed hair to move through the system efficiently.

If your cat is vomiting often and you are not sure whether it is really hairballs, start with the bigger picture. Is your cat eating normally? Is the vomit mostly hair, foam, or food? Is your cat acting normal afterward? For a wider look at possible causes, read Why Is My Cat Vomiting?.

How to help prevent hairballs

Grooming is the first line of defense. Regular brushing removes loose hair before your cat can swallow it. This matters even more for long-haired cats and during shedding season. Hydration also matters. A well-hydrated digestive tract generally moves things along better than a dry one.

Supportive ingredients can help too. Many pet parents look for gentle digestive support that also supports skin and coat health. Hemp Well Cat Hairball Soft Chews are made with hemp, pumpkin seed, and psyllium fiber to support hairball control and digestive function.

Could stress play a role?

Yes. Some cats groom more when they are stressed or when the household routine changes. That extra grooming can mean extra swallowed fur. If your cat seems especially tense during travel, visitors, grooming, or vet visits, gentle calming support may help reduce stress-related overgrooming in some cases. Calm Cat Oil is one option to consider if relaxation is part of the bigger picture.

When hairballs are not “just hairballs” anymore

Talk with your veterinarian if your cat is vomiting frequently, losing weight, refusing food, straining without producing a hairball, or acting lethargic. Hairballs should not become the catch-all explanation for every episode of vomiting. A vet can help rule out other digestive concerns and guide you on what is normal for your cat.

For many cats, hairball relief is about simple, repeatable habits: brushing, hydration, digestive support, and less stress. Once those pieces are in place, many cat parents see fewer messy surprises and a more comfortable cat.
