Vomiting / GI issues

Has your cat been vomiting more often?

Record frequency, contents, relation to meals and accompanying changes rather than assuming a hairball. Vomiting more than once a week warrants assessment, but reduced appetite or energy, blood, repeated retching or suspected exposure should not wait for an episode count.

Possible medical causes

Hairballs: bringing one up every one to two weeks isn't unusual for a healthy cat; rarely, a hairball passes into the intestine and gets stuck, causing a blockage that can be life-threatening
Foreign object ingestion: toxic plants, spoiled food, human medications, string/yarn, human foods (chocolate, onions, etc.)
Gastrointestinal disease: constipation, inflammatory bowel disease, intestinal parasites, tumors, or obstruction from a foreign object
Metabolic disease: diabetes, kidney disease, and hyperthyroidism can all present with vomiting

Possible behavioral causes

Record food, timing and environmental changes without assuming fast eating or a purely behavioral problem.

Initial at-home suggestions

Track how often vomiting happens and what comes up (food/hairball/clear liquid/blood)
Check your home for anything your cat might swallow — string and yarn need special caution
If you suspect a hairball issue, talk to your vet about whether a hairball remedy paste or a high-fiber diet would help
Contact the veterinarian promptly for repeated vomiting or warning signs; the more-than-weekly guidance does not make fewer episodes automatically safe.
