A hairball on the rug is an unpleasant but familiar part of sharing your home with a cat. Knowing how to prevent cat hairballs starts with a simple truth: cats will always swallow some loose fur while grooming. The aim is not to stop this natural behaviour, but to reduce the amount of hair swallowed and help it move through your companion’s digestive system comfortably.
An occasional hairball may be normal, particularly during a seasonal shed. Frequent retching, repeated vomiting or a cat that seems uncomfortable, however, deserves closer attention. Small, consistent changes to grooming, hydration and diet can make a meaningful difference for many cats.
Why cats get hairballs
Your cat’s tongue is covered in tiny backward-facing hooks that are very effective at lifting loose hair from the coat. Once swallowed, most fur passes through the gut and leaves in the litter tray. Sometimes it gathers in the stomach instead, forming the tube-shaped clump we recognise as a hairball.
Long-haired cats, cats with thick double coats and enthusiastic groomers are more prone to them. Indoor cats can also shed throughout the year because central heating and artificial light reduce the clear seasonal pattern seen outdoors. Stress, skin irritation, fleas and pain can lead to overgrooming too, which means a hairball problem can occasionally point to something more than shedding.
How to prevent cat hairballs with regular grooming
Regular grooming is usually the most effective place to begin. Every loose hair removed with a brush is one your cat is less likely to swallow. It also gives you a quiet opportunity to check your companion’s skin and coat for dandruff, redness, mats, parasites or tender areas.
Short-haired cats may benefit from a gentle brush once or twice a week, increasing this during moulting periods. Long-haired cats often need daily attention, especially around the chest, tummy, back legs and behind the ears, where tangles can form. Choose a brush suited to your cat’s coat rather than assuming firmer is better. A soft brush or grooming glove can be less intimidating for a sensitive cat, while a comb may be needed to work through a longer coat carefully.
Keep sessions brief and positive. Offer praise, stop before your cat becomes frustrated and gradually build the routine. Forcing grooming can make future sessions harder, particularly for rescue cats or companions who are wary of handling. If mats are tight to the skin, do not try to cut them out with household scissors. A vet or qualified feline groomer can remove them safely.
Support healthy digestion every day
Hair is easier to manage when the digestive system is working as it should. Water is especially helpful because good hydration supports normal gut movement and overall urinary health. Some cats naturally drink very little, so it can help to offer water in several quiet places, away from the litter tray and food bowls. A wide ceramic or metal bowl may suit cats that dislike their whiskers touching the sides.
Wet food can contribute valuable moisture to the daily diet. Whether to feed wet food, dry food or a combination depends on your cat’s preferences, health needs and the advice of your veterinary team. If you change food, do it gradually over several days to avoid upsetting a sensitive stomach.
Dietary fibre may help some cats pass swallowed hair more regularly. However, this is not a case of adding fibre indiscriminately. Too much, or a sudden change, can cause loose stools, constipation or reduced appetite. A complete cat food formulated for digestive support may be appropriate for some companions, but the right choice depends on their age, weight, stool quality and any existing condition.
Hairball pastes and condition-specific nutritional supplements can also be useful for certain cats, particularly those that struggle during heavy shedding. Look for products made for cats, with clear feeding guidance and safe, legal ingredients. A nutrition-led option should support a balanced routine, not replace grooming, water or veterinary care. If your cat takes medication or has a health condition, check with your vet before introducing a new supplement.
Make grooming less excessive
Not all grooming is simply good feline housekeeping. Cats may lick more when they are bored, anxious, itchy or uncomfortable. If your companion is spending long periods focused on one area of their body, take note. Fur thinning, bald patches, scabs or a sudden change in grooming habits are reasons to arrange a veterinary check.
At home, provide outlets that support calm, natural behaviour. A predictable routine, places to climb or hide, scratching surfaces and short daily play sessions can reduce boredom and help nervous cats feel more secure. For multi-cat homes, make sure there are enough separate resources such as beds, feeding areas, water bowls and litter trays. Tension between cats is not always obvious, but it can show up as overgrooming.
Parasite prevention matters here too. Fleas can cause significant itchiness, even when you do not spot an adult flea. Use a vet-recommended treatment schedule appropriate for your cat and household. Avoid dog flea products unless a veterinary professional has specifically said they are suitable, as some ingredients are dangerous to cats.
Be careful with home remedies
It can be tempting to reach for oils, butter or human laxatives after seeing a hairball. These are not reliable preventative measures and may upset your cat’s stomach, add unnecessary calories or create more serious problems. Never give human medication unless your vet has instructed you to do so.
Likewise, a cat that is repeatedly retching is not necessarily trying to bring up a hairball. Coughing, asthma, nausea and digestive disease can look similar at first. Treating every episode as a hairball risks delaying the right care.
When a hairball needs veterinary advice
A cat who brings up an occasional hairball and then returns to normal behaviour may only need more support with grooming and routine. But frequent episodes are not something to dismiss as a normal part of cat ownership. Contact your vet if hairballs occur regularly, increase suddenly or are paired with changes in appetite, weight, thirst, stools or energy.
Seek prompt veterinary advice if your cat repeatedly retches without producing anything, cannot keep food or water down, seems painful, has a swollen abdomen, is constipated, becomes unusually quiet or stops eating. A blockage is uncommon, but it can be serious. Kittens, senior cats and companions with long-term health conditions should be assessed sooner if they seem unwell.
Your vet can check for issues that may be contributing to hairballs, including dental pain, skin disease, parasites, inflammatory bowel problems or changes in gut motility. Bring a note of how often the episodes happen, what your cat produces and any changes you have noticed. This practical detail can help distinguish a passing nuisance from a pattern that needs treatment.
A manageable routine for fewer hairballs
For most pet parents, prevention works best when it is simple enough to maintain. Brush your cat consistently, particularly as the coat starts to shed more. Keep fresh water appealing and accessible, feed a complete diet that suits their individual needs, and watch for signs of itching or excessive grooming.
Do not expect a completely hairball-free life, especially with a long-haired companion. The more useful goal is fewer episodes, easier passage of swallowed fur and a cat who remains bright, comfortable and keen to eat. If you are unsure which type of digestive or coat support may suit your companion, use a guided product-selection approach or speak with your veterinary team. Thoughtful daily care is often the kindest way to keep hairballs from becoming a bigger problem.
