Occasional vomiting may be normal, but frequent vomiting needs attention. Causes include hairballs, parasites, food issues, and urinary blockage β€” judge by the vomit, frequency, and energy level.

1 Common Causes of Cat Vomiting

If your cat vomits only a few times a year and eats normally after, that’s normal β€” don’t worry. But if it vomits several times a week or even a day, take note; a disease may be present! Owners can judge by the vomit, frequency, and energy after, whether to see a vet.

Common causes of cat vomiting:

1. Hairballs

Hairball vomiting is normal and even healthy; ingested fur leaves as hairballs with vomit, without hurting appetite. But frequent hairballs are abnormal β€” then help reduce fur intake.

During shedding, brush often and give hairball paste or cat grass to prevent excess.

2. Internal parasites

Parasites cause poor appetite, diarrhea, and vomiting.

Parasites are common, especially in low-immunity kittens or cats that eat raw fish.

3. Food problems

Cats accept each food differently; if vomit has undigested kibble but energy and appetite are normal, try another food.

But don’t switch all at once β€” that can upset the stomach and cause gastroenteritis.

4. Urinary blockage

Blockage means no urination, usually from a suppressed excretory system trapping urine in the urethra. Trapped urine builds toxins, causing vomiting from pain or poison.

If no urine for over 48 hours, uremia, coma, even death may follow. So if vomiting, watch recent urination; if volume drops, act fast and take the cat to a vet!

Owners, when your cat vomits, don’t scold or hit it. Take it seriously β€” its health may be at risk; if you can’t solve it at home, go to a vet at once.
