My kitten has green eye boogers, vomit, and diarrhea. What's wrong?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed | 3 months and 12 days old | 4 lbs

Yesterday and today, I noticed that Nala had some green eye boogers in her eyes. I am not sure if that is a bad thing. But today, she hurled some white foamy vomit and right after she had some diarrhea. I'm not sure why this is happening. It might have something to do with me giving her too much food yesterday, OR because I changed her food (but I did the mix old and new food thing). Can someone please help me and tell me what could be causing this in her? Thank you.

Hello, sorry to hear about Nala. Both of those, giving too much food and changing her food may cause your kitten to feel sick. However, given her age and signs of eye discharge, I would also be concerned with an upper respiratory tract infection. Kittens may suffer from URIs intermittently and signs may last 3-5 days. If she is otherwise eating, drinking, and acting like her self then you can continue to monitor her at home. However, if you note any lethargy, persistent vomiting, diarrhea, labored breathing, or a decreased appetite then she needs to be re-revaluated by a veterinarian.

You may continue feeding her the new diet for now. You can also try to offer plain white rice and boiled skinless and boneless chicken with her new food.

Hope this helps and best of luck.
