Cat Hairballs: How to Prevent and Treat Naturally

By Rachel, Cat Care Specialist · Updated 2026-04-21

Every cat owner has heard the distinctive sound: that loud, retching cough followed by the unmistakable sight of a damp, tubular clump of fur on the carpet or floor. Hairballs are one of the most common feline experiences, and in most cases they are a normal, if unpleasant, part of cat ownership. But the question of what constitutes a normal hairball frequency, when hairballs signal something more serious, and how to genuinely reduce them without unnecessary medical intervention is one that many cat owners do not get clear answers to. This guide gives you those answers: a complete understanding of why cats get hairballs, which preventive measures actually work, which natural treatments have real evidence behind them, and the warning signs that mean a veterinary visit is needed.

What Are Hairballs and Why Do Cats Get Them?

A hairball — the medical term is trichobezoar — is a ball of fur that has accumulated in a cat's stomach or intestines. The mechanism of formation begins with grooming. A cat's tongue is covered in tiny, hook-like structures called filiform papillae that serve an important function in normal grooming: they pull dirt, debris, and loose fur away from the coat and toward the mouth, where the cat can then swallow it.

Most of the fur swallowed during grooming passes through the digestive tract normally and is excreted in the stool without any issue. The problem arises when fur accumulates in the gut faster than it can be moved through and excreted. This can happen because of the cat's grooming habits, the length and density of the coat, the texture of the fur, or — most importantly — the rate at which the digestive system moves material through.

The feline digestive tract is relatively short, and peristalsis — the wave-like muscle contractions that move material through the gut — is the mechanism that should move swallowed fur along. When peristalsis is sluggish, or when the volume of fur being swallowed is very high, fur can accumulate in the stomach and irritate the lining. The cat's natural response to stomach irritation is to vomit, and the accumulated fur is expelled in the process.

The tubular shape of a typical hairball comes from the cylindrical shape of the cat's oesophagus — the tube that carries food and other material from the mouth to the stomach. When a hairball is vomited, it is often the shape of a sausage or cylinder because it was formed in the oesophagus before reaching the stomach.

Not all hairballs are vomited. Some fur balls pass through the stomach and lodge in the intestines, potentially causing an obstruction. A hairball that has progressed to the intestines is more dangerous than a stomach hairball and is more likely to require veterinary intervention.

Normal vs. Abnormal Hairball Frequency

The threshold between normal and abnormal hairball frequency is not as well-defined as many sources suggest, but some general guidelines apply.

Normal hairball frequency: Most veterinarians consider occasional hairball vomiting — up to once per week — to be within normal limits for cats with access to regular grooming. The occasional hairball means the digestive system is doing its job of identifying and expelling fur that cannot be passed through normally.

When to be more attentive: More than one hairball per week, hairballs in short-haired cats (who swallow less fur than long-haired breeds due to less coat to groom), a noticeable increase in hairball frequency in any cat, hairballs accompanied by other symptoms, and any vomiting of blood along with a hairball.

Short-haired cats and hairballs: Many people are surprised to learn that short-haired cats can have hairball problems, and more significantly than some long-haired cats. The reality is that short-haired cats with skin conditions, allergies, or stress-related over-grooming can swallow enormous quantities of fur relative to their coat size. A short-haired cat that vomits frequent hairballs should be evaluated for underlying skin or behavioural conditions.

The critical question is not frequency alone, but the combination of frequency with other changes. A cat that vomits one hairball per week and is otherwise healthy, eating normally, and maintaining weight is likely fine. A cat that vomits two hairballs per week but is also lethargic, not eating well, and losing weight needs veterinary assessment.

When Hairballs Indicate a More Serious Problem

Hairballs can be a symptom of more serious conditions, and recognising when to see a vet is critically important.

Intestinal Blockage

The most serious hairball-related condition is a complete or partial intestinal blockage caused by a hairball mass that is too large to pass. This is more likely with hairballs that have formed in the intestines rather than the stomach. Signs of an obstruction include: repeated vomiting without producing a hairball, loss of appetite, lethargy, constipation (no bowel movements for more than 48 hours), a swollen or hard abdomen, pain when the abdomen is touched, and rapid weight loss. This is a veterinary emergency requiring immediate care.

Over-Grooming

Cats groom excessively in response to stress, skin pain, allergies, or parasitic infestations. When over-grooming is the driver of frequent hairball vomiting, treating the hairballs without addressing the underlying cause is ineffective. The solution is to identify and treat the cause of the over-grooming — behavioural stress, skin disease, allergies, or pain — which then reduces the grooming volume and the hairball frequency.

Signs that over-grooming rather than normal grooming is the issue include: hair loss in patches, damaged or broken fur, red or inflamed skin, a consistently dull or greasy coat despite normal appearance otherwise, and hairball frequency that seems disproportionate to coat length.

Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) affects the motility of the digestive tract — the normal wave-like contractions that move material through — causing it to slow down or become irregular. When gut motility is disrupted, swallowed fur cannot be moved through efficiently, and hairballs form. Cats with IBD typically show other symptoms alongside increased hairball frequency: chronic vomiting (not just hairballs), diarrhea, weight loss, and appetite changes.

IBD is diagnosed through biopsy and is manageable through diet and medication. If your cat has frequent hairball vomiting alongside any of the other symptoms above, discuss IBD with your veterinarian.

Megacolon

Megacolon is a condition where the colon becomes enlarged and loses its ability to contract efficiently, causing severe constipation. Fur balls that would normally be excreted can become lodged in the impacted colon. This is more common in older male cats. Signs include straining to defecate, hard and infrequent stools, vomiting (including hairball vomiting that may contain stool), and lethargy.

The Most Effective Prevention: Brushing

It is stating the obvious, but brushing is by far the most effective hairball prevention tool available, and it costs nothing beyond the price of a brush. The principle is simple: remove loose fur from your cat's coat before the cat swallows it during grooming.

For long-haired cats: Brush daily during shedding season, and two to three times per week otherwise. Use a slicker brush to work through the undercoat, then a wide-tooth comb to remove tangles and loose fur. A deshedding tool can be used weekly for deep undercoat fur removal.

For short-haired cats: Brush once or twice per week with a rubber curry brush or soft-bristled brush. The rubber curry brush is particularly effective at gathering loose fur from short coats and is well-tolerated by most cats. Short-haired cats that groom heavily may need more frequent brushing if over-grooming is a factor.

For cats that dislike brushing: The rubber curry glove technique is often a breakthrough for brush-averse cats. The soft rubber teeth feel like petting rather than grooming, and most cats accept it immediately. Once they accept the glove, progress to a standard brush for brief sessions, always ending with a treat.

Brushing tools by coat type:

  • Long-haired: Slicker brush + wide-tooth comb + deshedding rake
  • Medium-haired: Slicker brush + rubber curry brush
  • Short-haired: Rubber curry brush or soft-bristled brush

Regular brushing also gives you an opportunity to check for skin conditions, parasites, mats, and other coat health issues that would otherwise go unnoticed.

Dietary Approaches to Hairball Prevention

Diet directly affects hairball formation in several ways: the moisture content of the food, the fibre content, and the digestibility of the formula.

Moisture Content

Wet food contains approximately 75–85% water, compared to roughly 10% in dry kibble. This additional moisture supports healthy digestion and gut motility, helping fur pass through the digestive tract more easily. Cats on wet food diets typically have fewer hairball issues than cats on exclusively dry food diets.

Switching from dry to wet food is one of the most evidence-based dietary changes for hairball reduction. Even adding one wet food meal per day to a predominantly dry food diet provides meaningful benefit.

Fibre Content

Moderate dietary fibre supports gut motility — the peristaltic contractions that move material through the digestive tract. Some fibre also helps bind water in the gut, softening material and making it easier for fur to pass through.

Pumpkin (plain, canned, not the spiced pie filling) is a traditional natural source of soluble fibre used for hairball management. A teaspoon mixed into wet food a few times per week adds fibre and moisture. Pumpkin is low in calories and safe for cats, though some cats dislike the texture and will refuse food with it mixed in.

Commercial hairball-formulated treats and foods use added cellulose or other fibres specifically for this purpose. The evidence for their effectiveness is mixed — some cats respond well, others do not.

Digestibility

Highly digestible foods are less likely to leave residue in the gut and allow material to pass through more efficiently. The most digestible cat foods use high-quality animal protein as the primary ingredient rather than plant-based fillers. Foods with named meat proteins — chicken, turkey, salmon, rabbit — are more digestible than foods that list generic meat by-products first.

For cats with chronic hairball issues that do not respond to brushing and dietary fibre, a switch to a highly digestible formula may help. Your veterinarian can recommend an appropriate therapeutic digestive diet if hairballs persist despite other interventions.

Foods to Avoid

Some foods contribute to hairball formation or worsen the problem. Very dry kibble without moisture content means the gut has to work harder to move material, and fur can accumulate more easily. Low-quality foods with high plant content leave more undigested residue in the gut. Sudden food changes can disrupt gut motility temporarily, causing fur to accumulate during the adjustment period.

Natural Remedies That Actually Work

Several natural remedies for hairball prevention have genuine evidence behind them, while others are more folklore than effective science.

Pumpkin (Puree)

Plain canned pumpkin (not spiced pumpkin pie filling) is a well-established natural remedy for hairball management. The soluble fibre in pumpkin absorbs water and forms a gel that helps lubricate the digestive tract and softens material, allowing fur to pass through more easily. One to two teaspoons mixed into wet food a few times per week is the standard recommendation. Adjust based on your cat's size — smaller cats need less.

Coconut Oil

Coconut oil in small amounts — one quarter to one half teaspoon per day — acts as a natural lubricant in the digestive tract and also has mild anti-inflammatory properties. Some cats respond very well to coconut oil supplementation for hairball management. Others do not tolerate it, and some develop diarrhoea from it. Start with a very small amount and assess tolerance before making it a regular supplement.

Olive Oil

Like coconut oil, olive oil provides a lubricating effect in the gut. One-quarter teaspoon added to wet food a few times per week is the typical dose. Olive oil is less ideal than coconut oil because the fatty acid profile is different and it provides less of the specific medium-chain fatty acids that have antimicrobial and anti-inflammatory properties, but it is a workable alternative.

Hairball Pastes and Malt

Commercial hairball pastes, typically malt-flavoured, use petroleum-based or plant-based laxatives to lubricate the gut and stimulate fur passage. These are effective in the short term but are not ideal as long-term daily solutions because they work by irritating the gut lining slightly to stimulate peristalsis. They are best used occasionally — when you notice a cat retching but not producing — rather than as a daily preventive.

Omega-3 Fatty Acids

Omega-3 fatty acids from fish oil support skin and coat health, which reduces shedding (less loose fur means less swallowed fur) and also reduce intestinal inflammation that can slow gut motility. A cat with a healthy coat sheds less, swallows less fur, and moves material through the gut more efficiently. Omega-3 supplementation is one of the most evidence-based long-term hairball prevention strategies.

Probiotics

A healthy gut microbiome supports normal digestion and gut motility. Probiotic supplements designed for cats — not human probiotics — can help maintain the bacterial balance in the gut that supports efficient digestion and fur passage. Probiotics are particularly worth considering for cats with a history of digestive upset or cats that have been on antibiotics recently.

At-Home Treatment During a Hairball Episode

When your cat is actively retching and trying to vomit a hairball, the best thing you can do is remain calm and observe. The retching and vomiting process is distressing to watch, but it is usually harmless and the hairball will come up within a few minutes. Do not put your hand in the cat's mouth — a retching cat may bite involuntarily.

After the hairball is expelled, offer fresh water. Some cats are thirsty after a vomiting episode. Give your cat space — they will clean themselves up and rest.

If your cat has retched multiple times but produced nothing, or if the retching seems unproductive, a small amount of olive oil or coconut oil (one quarter teaspoon) may help lubricate the passage. Do not give oil more than twice in 24 hours.

When the episode is over, review your prevention regimen. Was the cat brushed recently? Has there been a change in diet or environment that might be causing more grooming? Is this frequency unusual for this cat? Use each hairball episode as a prompt to assess whether your prevention strategy needs adjustment.

Hairballs in Long-Haired vs Short-Haired Cats

Long-haired cats — Persians, Maine Coons, Ragdolls, Himalayans, British Longhairs — are more predisposed to hairballs simply because their coats generate more fur material. More surface area means more fur to groom, more loose undercoat to accumulate, and more opportunity for mats to form that the cat will try to groom out.

For long-haired cats, daily brushing is the baseline. During heavy shedding seasons (typically spring and autumn for indoor cats), brushing daily may need to increase to twice daily. A deshedding tool used weekly dramatically reduces the undercoat fur load. Long-haired cats should also see a professional groomer every few months for a sanitary clip and undercoat de-shedding that is difficult to do thoroughly at home.

Short-haired cats with a healthy coat and normal grooming habits should not have frequent hairballs. A short-haired cat that is vomiting hairballs regularly is not having a coat problem — they are having a behaviour or medical problem that needs investigation. Excessive grooming from stress, allergies, or skin pain is the likely culprit.

Senior Cats and Hairballs

Senior cats face additional hairball challenges beyond the normal grooming mechanism. Arthritis can make grooming physically difficult, leading to a duller, more tangled coat that generates more loose fur. Reduced gut motility from age-related changes in the digestive tract means swallowed fur moves through more slowly. Cognitive decline can cause cats to groom excessively as a displacement behaviour or to forget to groom at all.

For senior cats, the prevention approach should be more proactive. Brushing your senior cat at home removes the fur they struggle to groom themselves, which is especially valuable for cats with mobility limitations. Switching to wet food or adding moisture to the diet supports the slower gut motility of older cats. Probiotic supplementation is particularly beneficial for senior cats, whose gut microbiome can become imbalanced with age and medication use.

If your senior cat has a sudden increase in hairball frequency, a veterinary check that includes blood work, thyroid assessment, and gut motility evaluation is the appropriate first step.

Frequently Asked Questions

What exactly is a hairball and why do cats get them?

A hairball (trichobezoar) is an accumulation of swallowed fur in the stomach or intestines. Cats groom by licking their coat, and their tongue's hook-like papillae pull loose fur into the mouth. Most fur passes through the digestive tract normally, but when accumulation outpaces passage, the stomach expels it as a hairball.

How often is it normal for a cat to vomit a hairball?

Occasional hairball vomiting — up to once per week — is considered normal for most cats. More frequent vomiting, especially in short-haired cats, may indicate over-grooming from stress or a medical condition and warrants veterinary assessment.

Can hairballs be dangerous for cats?

Yes. In rare cases, a hairball can grow large enough to cause an intestinal obstruction. Signs include repeated vomiting without producing a hairball, loss of appetite, lethargy, constipation, and a swollen abdomen. These symptoms require immediate veterinary attention.

What natural remedies help prevent hairballs in cats?

Regular brushing is the most effective natural remedy. Dietary fibre (pumpkin puree), natural oils (coconut or olive oil in small doses), omega-3 fatty acids, adequate hydration (wet food), and probiotic supplements all support the digestive system's ability to move fur through without accumulating it.

Does switching to wet food reduce hairballs?

Yes. Wet food adds moisture to the diet, which supports gut motility and helps fur pass through the digestive tract more easily. Switching from dry kibble to wet food or adding a wet food meal to the diet measurably reduces hairball frequency in most cats.

What is the best brush for reducing cat hairballs?

A slicker brush or deshedding tool (like the Furminator) is most effective for removing loose fur before ingestion. Rubber curry brushes work well for short-haired cats. Long-haired cats benefit from a slicker brush combined with a wide-tooth comb.

My cat keeps retching but nothing comes up. Is that normal?

Retching without producing a hairball could indicate nausea, a partial blockage, or another medical issue. If retching is frequent or accompanied by lethargy, not eating, or a swollen abdomen, see your vet to rule out an obstruction.

Can hairballs indicate a more serious health problem?

Yes. Frequent hairball vomiting, especially in short-haired cats, can indicate over-grooming from stress, allergies, parasites, or pain. Cats with inflammatory bowel disease or megacolon have increased hairball frequency. Frequent hairballs should always be discussed with your veterinarian.
