Why does my cat throw up after eating?

Cats that vomit right after meals are often eating too fast. Food switches, hairballs, food sensitivities and, in older cats, kidney disease, thyroid disease or bowel disease are other causes.

Try: a slow feeder or puzzle feeder, smaller and more frequent meals, and switching foods gradually over 7–10 days.

See a vet if: it happens more than once a week, your cat loses weight, there's blood, or your cat stops eating for more than a day.
