Understanding Hairballs in Cats: Causes, Symptoms, and Prevention

By Purr-Bark • Updated: October 25, 2025

Hairballs — or trichobezoars — are one of the most common issues cat owners face. While it’s normal for cats to groom themselves and swallow a bit of fur, excessive hairball formation can be a sign of digestive or grooming problems. Here’s everything you need to know to keep your cat healthy and comfortable.

What Are Hairballs?

When cats groom themselves, they use their rough tongues to remove loose fur. Most of this fur passes through the digestive system without issue — but sometimes, it clumps together in the stomach, forming a hairball that your cat later vomits up.

Causes of Hairballs

• Excessive grooming or anxiety-related licking
• Long-haired breeds like Persians and Maine Coons
• Seasonal shedding, especially in spring and fall
• Poor diet or lack of fiber
• Infrequent brushing by owners

Symptoms to Watch For

Occasional hairball vomiting is normal, but if you notice these signs, it could indicate a blockage or underlying problem:

• Frequent gagging or hacking without producing a hairball
• Loss of appetite
• Lethargy or constipation
• Swollen abdomen or discomfort

⚠️ When to See a Vet: If your cat keeps trying to cough up a hairball but nothing comes out — or stops eating — visit your veterinarian immediately. A blockage could become life-threatening.

How to Prevent Hairballs

Fortunately, hairballs can be managed and minimized with a few simple steps:

• Brush your cat regularly: Especially long-haired breeds to remove loose fur.
• Provide a balanced diet: High-fiber cat foods or hairball-control formulas help fur pass naturally.
• Encourage hydration: Water aids digestion and reduces fur buildup.
• Use vet-approved hairball remedies: These mild laxatives help prevent fur clumping.

Final Thoughts

Hairballs are a natural part of feline grooming, but frequent or severe cases may point to a deeper issue. By maintaining regular grooming, a healthy diet, and frequent vet checkups, you can keep your cat comfortable and hairball-free.
