Cat Hairballs: Causes, Prevention, and When to Call a Vet
Reduce swallowed fur through grooming, hydration, and diet—and recognize when repeated retching is not a simple hairball.
Hairballs begin with grooming
A cat's backward-facing tongue collects loose fur, most of which passes through the digestive tract. A hairball forms when enough hair remains in the stomach to be brought back up. An occasional episode can be normal, especially during shedding season.
Frequent hairballs can reflect extra shedding, overgrooming, skin disease, digestive problems, or simply a coat that needs more help from a brush.
Reduce the amount swallowed
Brush short-haired cats several times a week and long-haired cats daily, using a tool that removes loose undercoat without scratching the skin. Keep sessions brief and pair them with treats.
- Increase water access with fresh bowls or a fountain
- Feed a complete diet and discuss fiber changes with your veterinarian
- Address fleas, itching, stress, or pain that may drive overgrooming
Be cautious with home remedies
Do not give oils, butter, or human laxatives. Some commercial hairball products can be useful for individual cats, but repeated use may interfere with nutrition or hide an underlying condition. Ask your veterinarian before adding one routinely.
Retching is not always a hairball
Repeated unproductive retching, coughing, breathing changes, appetite loss, constipation, lethargy, or abdominal pain needs veterinary care. Cats with asthma are often mistaken for cats trying to produce a hairball, so record a video of an episode if you can do so safely.
