My kitten is vomiting, has diarrhea, and is very tired. What to do?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed | 2 lbs

My kitten (female about 12 weeks old) is vomiting bile and has diarrhea. She's really tired and not herself. We don't know if she got into anything while we went out. I'm really concerned about her!

Hi and thanks for your post!

It is hard to say what exactly the issue with Ollie is sight unseen without examining her first, but I can offer a few insights.

Parasites, viral infections (especially if not up to date on her core vaccines), dietary indiscretion (eating something other than her normal kitten food) or an intestinal obstruction can all cause vomiting and diarrhea.

My best advise is to take her into your veterinarian soon to have these potential issues above ruled out.

Thank you for using Petco Pet Education Center, formerly Petcoach!
