My 11-month-old cat throws up right after eating. What's wrong?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | unneutered | 11 months and 3 days old | 10.36 lbs

I have an 11-month-old DSH indoor cat who has recently started vomiting within minutes of eating. This started Friday morning. He seems to be peeing and drinking fine. I have seen him drink a little more than usual on two consecutive mornings before the vomiting started on Friday. I'm not sure how his poops are as I haven't seen him poop lately and I have three other cats. He is able to keep down small amounts of watery sardines. He's fairly active, healthy-looking and has dark pink gums.

Poor Splash! This vomiting could be caused by a GI illness, eating something rotten, a foreign body, or pancreatitis. Given that he has been vomiting since Friday morning, it's time to see a vet as soon as possible. The vet can diagnose what is causing the vomiting so he can be treated . I would take Splash into a vet now.
