Hairballs form when swallowed fur collects in a cat’s stomach instead of passing normally through the digestive tract. Although an occasional hairball may not cause lasting problems, frequent vomiting, repeated unsuccessful retching, appetite loss or lethargy should be assessed by a veterinarian.
Quick Summary
- Hairballs develop from fur swallowed during normal grooming.
- Most swallowed hair passes through the digestive tract naturally.
- Regular brushing can reduce the amount of loose fur a cat swallows.
- Frequent vomiting or repeated unsuccessful retching should not be dismissed as normal.
- Dietary fibre, specialised diets or hairball products may help some cats when used appropriately.
What Are Hairballs?
Hairballs are clumps of swallowed fur that collect inside a cat’s stomach. Their medical name is trichobezoars.
When cats groom themselves, the backward-facing structures on their tongues collect loose fur. Some of this fur is swallowed. Because hair cannot be digested, it normally travels through the gastrointestinal tract and leaves the body in the stool.
When some of the swallowed fur remains in the stomach, it can gather into a dense mass. The cat may eventually vomit the accumulated hair.
Despite the name, a vomited hairball is often not round. It commonly looks damp and cylindrical because it has been compressed while passing through the oesophagus.1, 2
Why Do Cats Get Hairballs?
Hairballs begin with normal grooming behaviour. The greater the amount of loose fur a cat swallows, the greater the opportunity for some of it to accumulate in the stomach.
Normal grooming
Cats naturally swallow fur while cleaning themselves. Hairball episodes may become more noticeable during periods of heavier shedding, when more loose fur is available to ingest.1, 3
Coat length
Long-haired cats may swallow more fur and can require more frequent grooming support. Regular brushing removes loose hair before the cat has an opportunity to swallow it.2, 3
Excessive grooming
A cat that begins grooming much more than usual may swallow an unusually large amount of fur. Excessive licking can be associated with skin irritation, parasites, allergies, pain or behavioural stress.
Consult a veterinarian when increased grooming is accompanied by bald areas, irritated skin, wounds or other behavioural changes.4
Gastrointestinal conditions
Frequent hairballs or recurrent vomiting may occasionally be associated with a gastrointestinal condition that interferes with the normal movement of stomach contents. Repeated vomiting should therefore not automatically be attributed to hairballs.5
What Does a Hairball Episode Look Like?
Before bringing up a hairball, a cat may:
- Crouch close to the floor
- Extend its neck
- Make hacking, gagging or retching movements
- Vomit fluid, food or a cylindrical mass of hair
Coughing, gagging and vomiting can also have causes unrelated to hairballs. Respiratory problems, gastrointestinal disease and other medical conditions may sometimes look similar to a hairball episode.
Coughing originates from the respiratory tract, while retching and vomiting involve the digestive tract. It can be difficult for an owner to tell the difference, particularly during a brief episode.
When Should You Contact a Veterinarian?
Seek veterinary advice if your cat:
- Repeatedly retches without producing a hairball
- Vomits frequently or over several days
- Stops eating or has a reduced appetite
- Becomes unusually quiet or lethargic
- Shows signs of abdominal pain
- Develops persistent constipation
- Loses weight
- Has difficulty breathing or appears to be coughing
In uncommon cases, a dense mass of hair can remain in the stomach or contribute to gastrointestinal obstruction. Veterinary investigation and treatment may then be required.1, 6
Important: There is no single hairball frequency that is normal for every cat. A new, increasing or persistent pattern is more important than any fixed number. Speak with your veterinarian when hairball episodes become frequent or occur alongside other symptoms.
How to Help Reduce Hairballs
Hairball management generally focuses on two goals:
- Reducing the amount of loose fur swallowed during grooming
- Supporting the normal passage of ingested hair through the digestive tract
1. Brush your cat regularly
Regular brushing is one of the most consistently recommended ways to reduce hair ingestion. It removes loose fur before the cat swallows it while grooming.2, 3
The ideal grooming frequency depends on coat length, shedding level and how well the cat tolerates brushing. Long-haired cats generally need more frequent grooming than short-haired cats.
2. Investigate excessive grooming
Pay attention to changes in your cat’s coat and grooming behaviour. Look for:
- Bald or thinning areas
- Red or irritated skin
- Fleas or signs of other parasites
- Repeated licking of one area
- Sudden behavioural changes
A veterinarian can help determine whether skin disease, pain, parasites or stress may be contributing to the behaviour.
3. Maintain an appropriate diet
A complete and balanced diet should remain the foundation of your cat’s nutrition. Some specialised hairball diets and supplements include additional fibre intended to support the movement of ingested hair through the gastrointestinal tract.
Any major dietary change should be introduced gradually. A veterinarian can help determine whether a specialised diet or added fibre is appropriate for your cat.
4. Provide fresh drinking water
Fresh water should always be available. Adequate hydration supports general gastrointestinal health, although water alone should not be presented as a treatment for hairballs.
Some cats may be encouraged to drink by providing:
- Several water bowls around the home
- Wide, shallow bowls
- A regularly cleaned water fountain
- Wet food as part of an appropriate diet
5. Consider an appropriate hairball product
Hairball pastes, gels, diets and supplements do not all work in the same way. Some provide lubrication, while others provide fibre or additional digestive support.
Choose products according to their ingredients, feeding directions and suitability for your cat. Lubricating products should be used according to label directions or veterinary advice.7
A supplement should never delay veterinary assessment when a cat has frequent vomiting, appetite changes or possible signs of obstruction.
Hairball Paste, Treats, Diets or Supplements?
The format alone does not determine whether a product is suitable. Its formulation, dosage and intended purpose are more important.
| Option | Typical role | Potential advantage | What to check |
|---|---|---|---|
| Hairball paste or gel | Lubrication and passage of hair | Direct and familiar format | Ingredients, dosage and veterinary suitability |
| Hairball treats | Convenient delivery | May be easy to add to a routine | Calories, serving size and ingredient quantities |
| Fibre-based supplement | Support passage of ingested hair | May suit ongoing management | Fibre source, daily amount and tolerance |
| Specialised hairball diet | Daily nutritional management | Combines nutrition with a hairball-focused formulation | Whether it is complete and balanced for the cat’s life stage |
| Multi-ingredient supplement | Ongoing digestive support | May combine fibre and other functional ingredients | Ingredient evidence, amounts and feeding directions |
When comparing options, consider:
- How frequently your cat experiences hairballs
- Whether vomiting or other digestive symptoms are recurring
- Your cat’s age and general health
- How easily the product can be fed
- Whether it is intended for occasional or daily use
- Whether veterinary investigation is needed first
MIHIJO Care Tip
Hairball care works best as a routine rather than a single action. Regular grooming, appropriate nutrition and careful monitoring of changes in your cat’s symptoms can help you respond before an occasional issue becomes a recurring concern.
A Practical Hairball Care Routine
For a generally healthy cat that experiences occasional hairballs, a practical routine may include:
- Brush regularly, especially during heavier shedding periods.
- Monitor how often vomiting, gagging or retching occurs.
- Check for excessive grooming, fleas or skin irritation.
- Provide a complete and balanced diet with fresh water available.
- Discuss specialised diets, fibre or hairball products with a veterinarian if episodes recur.
- Seek veterinary attention for persistent vomiting, unsuccessful retching, appetite loss, lethargy, constipation or breathing difficulty.
Key Takeaways
- Hairballs form from fur swallowed during grooming.
- Occasional episodes can occur in otherwise healthy cats.
- Frequent or worsening episodes may be associated with excessive grooming or an underlying health problem.
- Regular brushing is one of the most widely recommended preventive measures.
- Specialised diets, fibre and hairball products may assist some cats, but suitability depends on the individual animal.
- Repeated vomiting, unsuccessful retching, appetite loss, lethargy, constipation or breathing difficulty requires veterinary attention.
