My kitten is throwing up bile and foam. Could it be his new food?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 4 months old

Recently he begins throwing up bile, like yellow stuff with a little food. I thought it was because of this new food. He threw up again white foam the next day. 2 days later he threw up the same yellow stuff (but I did give him the same new food) and then 2 days ago he threw up the foam again but he was hacking like he was trying get something out & all that came out was foam again. Ive changed his food since then and he hasn’t throw up yet, its only been a day. He still eats and plays regular.

Poor kitty. It sounds like Kovu has a pretty sensitive stomach. It is best to either keep him on the same food and not make any changes in the brand, or look into a prescription diet food designed for pets with food sensitivity, such as Royal Canin Gastrointestinal, Hills Z/D ultra, or Royal Canin Hydrolyzed protein. There aren’t a lot of options for kittens however, except for the Royal Canin hydrolyzed protein high energy. Since things are going well now, I wouldn’t make any changes to his diet. Continue to monitor him for continued vomiting and if seen it’s best to get him to your vet for anti-nausea medication and a probiotic to calm things down until his body regulates again. The vet will also check him over to ensure there is nothing else underlying going on here such as intestinal parasites or a bacterial infection. I hope that your fur baby Kovu has some resolve to his stomach issues soon! Best wishes and take care.
