My 5-week old kitten is vomiting and has diarrhea. What should I do?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed | 1lb

My 5 week old kitten just started eating canned food. In a pinch I gave her some human formula and she then soon after started vomiting and having diarrhea. This was 3 days ago and she is still having the same diarrhea and occasional vomiting. Is she still being affected by the human formula or is it the canned food? She is acting normal otherwise. What should I do?

I would be concerned that there may be something else causing her to vomit and have diarrhea. Canned food could cause some diarrhea but I wouldn't expect vomiting for several days as well. And while the formula could be the culprit it still sounds like she needs treatment at this point. At her age I would worry about intestinal parasites, infections or even ingestion of a foreign object. I would recommend seeing a veterinarian for an examination. Young kittens can become dehydrated or hypoglycemic quickly, sonthe sooner you can see a vet the better.
