Hairballs form when swallowed fur clumps in the stomach instead of passing through. Long-haired and heavy-shedding cats are prone, but any groomer can develop them. Prevention focuses on reducing swallowed hair and helping gut motility.

Brush frequently to remove loose coat before the cat ingests it; during seasonal shedding, daily brushing often helps most. Professional grooming may be needed for dense or mat-prone coats. Dietary fiber from veterinarian-recommended hairball formulas or prescribed fiber supplements can move hair through the digestive tract more reliably for some cats.

Commercial hairball pastes or gels often contain lubricants or mild laxatives; use only as directed on the label or by your veterinarian, especially if your cat has chronic disease or takes other medications. Always provide fresh water because dehydration worsens constipation and hairball risk.

Increase environmental enrichment and play so normal eating and drinking rhythms stay steady. Frequent vomiting, retching without producing vomit, lethargy, constipation, or belly pain are not routine hairball signs and can indicate obstruction or other emergencies. Seek prompt veterinary care for those symptoms rather than repeating home remedies.
