How often should a cat bring up hairballs?
An occasional hairball is part of being a cat; weekly retching or gagging without producing one is not.
Cats swallow loose fur while grooming, and most of it passes through the gut unnoticed. Now and then the hair collects in the stomach and comes back up as a tube-shaped wad. A hairball once in a while — on the order of once or twice a month or less — is generally considered within the normal range for healthy cats.
When hairballs stop being routine
Frequency creeping up to weekly, repeated retching that never produces a hairball, appetite loss, or constipation can point to something else — gastrointestinal motility problems, food sensitivity, or fur swallowed in excess because of itchy skin. These patterns deserve a veterinary work-up rather than another tube of hairball paste.
Prevention is mostly mechanical: regular brushing removes fur before it is swallowed, and long-haired breeds need it far more often than short-haired cats — the right routine varies with coat type and season. If hairballs remain frequent despite brushing, discuss diet options with a veterinarian.
