Cat Vomiting

Cat

Occasional vomiting in cats can be normal (such as hairballs), but frequent or severe vomiting is a cause for concern. Vomiting involves the forceful expulsion of stomach contents and should be distinguished from regurgitation, which is passive and involves undigested food.

Possible Causes

  • Hairballs, especially in long-haired breeds
  • Eating too fast or dietary indiscretion
  • Food allergies or sensitivity
  • Intestinal parasites (roundworms, tapeworms)
  • Inflammatory bowel disease (IBD)
  • Kidney disease or renal failure
  • Hyperthyroidism
  • Pancreatitis
  • Ingestion of toxic plants (lilies, poinsettia) or chemicals
  • Foreign body obstruction

When to See a Vet
Important

Seek veterinary care if any of the following apply:

  • Vomiting occurs more than 2-3 times in 24 hours
  • Vomit contains blood (bright red or dark, coffee-ground appearance)
  • Your cat is also lethargic, not eating, or has diarrhea
  • Vomiting persists for more than 24 hours
  • You suspect your cat ingested something toxic or a foreign object
  • Your cat is losing weight or vomiting has become chronic
  • Your cat is a kitten or senior (higher risk of dehydration)

First Aid Tips
Home Care

These tips can help while you monitor the situation or wait for your vet appointment:

  1. Withhold food for 12 hours but keep fresh water available
  2. After 12 hours, offer small amounts of bland food (boiled chicken and rice)
  3. Ensure your cat stays hydrated — offer ice cubes or a small amount of chicken broth
  4. Remove any potential toxins or dangerous items from your cat's environment
  5. Monitor litter box usage for signs of diarrhea or constipation
  6. Keep a log of vomiting episodes (timing, contents, frequency) for your vet
