My 4-month-old kitten throws up undigested food on Science Diet. Why?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 3 months and 10 days old | 4.8 lbs

My 4 month old kitten continues to throw up his undigested food. This is now the 7th time in only the 2 months I have had him. I have tried feeding him smaller portions throughout the day instead of two bigger portions a day. He is on Science Diet Kitten which is what our vet recommended so I'm not sure if it's the food or not. Any thoughts would be helpful just looking for another suggestion our current vet seems to think he plays to hard after eating but he rarely plays after he has just eaten

It may be a dietary intolerance to the Science Diet food. You can try switching to a different brand or try feeding wet food instead of dry. If Gucci still vomits after trying a different food, then there may be another cause for the vomiting, such as hairballs, acid reflux, eating too fast, or even disorders with the stomach or intestines that delay digestion. You can discuss these possibilities with your vet, and they may recommend medications or diagnostics such as ultrasound or a barium study to see if things are moving through his system with the normal speed or not.
