My cat ate kitten food, now vomiting and has diarrhea. What to do?
Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Buddy. How lovely of you to take in this stray kitten!! Yes I suspect it's the kitten food causing Buddy to have an upset stomach and vomit. Sudden changes in diet can lead to these symptoms. Feed him a bland diet of boiled white meat chicken (no bones or skin) in small amounts a couple times a day for a few days, the start slowly adding in his normal diet. If he refuses to eat the bland diet, vomits the bland diet, stops drinking water, starts vomiting water, continues to have diarrhea, has blood in his stool, and/or becomes very lethargic, he will need to see a vet immediately. I hope this helps!
