Hairballs: Normal or Not?

Hairballs (trichobezoars) are a fact of life for most cat owners. But understanding the difference between occasional and excessive hairballs can help you support your cat’s health.

What’s Normal?

Most cats produce a hairball once every 1–2 weeks. Long-haired breeds may produce them more frequently. A “normal” hairball is tubular, made of compressed hair, and comes up with minimal distress.

When Hairballs Are a Problem

• More than one per week

• Retching or gagging without producing a hairball

• Lethargy or appetite loss alongside hairball episodes

• Constipation or diarrhea (a hairball may be causing a blockage)

How to Reduce Hairballs

• Regular brushing: Removes loose fur before your cat swallows it (see Grooming guide)

• Hairball-formula food: Contains extra fiber to help hair pass through

• Hydration: Adequate water intake supports healthy digestion

• Petroleum-based hairball remedies: Available over-the-counter, help lubricate hair passage

A cat who is retching frequently without producing anything needs a vet visit — this could indicate a gastrointestinal blockage. See our Cat Health pillar page.
