What Are Hairballs and Why Do Cats Get Them?
If you share your home with a cat, you have almost certainly encountered the unmistakable retching sound that precedes a hairball landing on your kitchen floor. As unpleasant as the experience is for both of you, hairballs are a natural consequence of your cat's grooming behaviour. Understanding why they form and what you can do about them can make life considerably more comfortable for your cat.
Cats are meticulous groomers. Their tongues are covered in tiny, backward-facing barbs called papillae, which are excellent at detangling fur and removing debris. The downside is that loose hair gets swept into the mouth and swallowed rather than spat out. Most of this hair passes harmlessly through the digestive tract. However, some of it accumulates in the stomach and forms a compacted mass — a hairball, or in veterinary terms, a trichobezoar.
Long-haired breeds such as Persians, Maine Coons, and Ragdolls are more prone to hairballs, as are cats that groom excessively due to stress or skin irritation. Older cats tend to develop more hairballs than kittens because they become more proficient groomers over time.
Signs Your Cat Has a Hairball Problem
Occasional hairball production — once or twice a month — is considered normal for most cats. What you should watch for are signs that a hairball is not being expelled and may be causing a blockage or discomfort.
- Repeated, unsuccessful retching or gagging without producing a hairball
- Loss of appetite or sudden disinterest in food
- Lethargy and reduced activity levels
- Constipation or conversely, diarrhoea
- A distended or tender abdomen
- Passing small amounts of hair in faeces
These symptoms, particularly when they persist beyond 24 to 48 hours, warrant a prompt call to your vet. A hairball lodged in the intestine rather than the stomach can become a life-threatening obstruction requiring surgical intervention.
Practical Prevention Strategies
Prevention is far preferable to treatment, and there are several straightforward approaches that can meaningfully reduce how many hairballs your cat produces.
Regular Brushing
The single most effective intervention is regular grooming. Brushing your cat removes loose, dead fur before it can be ingested. For short-haired cats, two to three sessions per week is usually sufficient. Long-haired breeds benefit from daily brushing. Many cats come to enjoy grooming sessions once they are introduced gradually and paired with positive reinforcement. Use a slicker brush or a fine-toothed comb appropriate to your cat's coat type.
Diet and Fibre
Diet plays a significant role in how well hair moves through the gastrointestinal tract. Specialised hairball-control cat foods contain elevated levels of dietary fibre, which helps propel ingested hair along the digestive system rather than allowing it to accumulate. Look for foods with added psyllium husk, beet pulp, or cellulose. These are well-supported by feline nutritional research as safe and effective.
Hydration also matters. Cats that drink more water tend to have better intestinal motility. If your cat is reluctant to drink from a bowl, a cat water fountain may encourage better fluid intake, which supports digestion overall.
Hairball Lubricants and Supplements
Petroleum-based hairball remedies, which typically come in a paste or gel form, work by lubricating the digestive tract and helping hair pass through more easily. These products are widely used and generally considered safe for short-term use. They are usually flavoured with malt or fish to improve palatability. However, they are not suitable for daily long-term use, as they can interfere with the absorption of fat-soluble vitamins.
Natural alternatives include small amounts of tinned pumpkin (plain, not pie filling) or a teaspoon of coconut oil added to food occasionally. While the evidence base for these is largely anecdotal, they are harmless in small quantities for most cats and may provide mild benefit.
Home Remedies Worth Considering
Beyond commercial products, some everyday adjustments at home can make a meaningful difference.
- Provide access to cat grass or oat grass, which some cats instinctively eat to aid digestion and induce vomiting of hairballs
- Offer wet or raw food as part of the diet, since higher moisture content supports gut motility
- Introduce interactive play to reduce stress-related over-grooming
- Consider a probiotic supplement formulated for cats, which supports a healthy gut environment
None of these approaches should replace veterinary advice if your cat is showing signs of distress, but they are reasonable supportive measures for cats with mild, recurring hairball issues.
When Hairballs Signal Something More Serious
It is worth emphasising that frequent hairballs — more than once or twice per week — are not something to simply manage at home indefinitely. Recurring hairballs can indicate an underlying issue such as inflammatory bowel disease, hyperthyroidism, or a skin condition causing excessive grooming. Your vet may recommend bloodwork, an ultrasound, or dietary trials to rule out these possibilities.
If your cat has not produced a hairball but has been retching repeatedly, do not wait and see. An intestinal blockage is a surgical emergency, and early intervention leads to significantly better outcomes. Trust your instincts — if your cat seems unwell, getting professional eyes on the situation is never the wrong choice.
Managing hairballs is largely about consistency. A good grooming routine, a well-chosen diet, and a basic understanding of what is normal for your individual cat will go a long way towards keeping this common feline nuisance firmly under control.
