My 9-week-old kitten has yellow diarrhea and is tired. What's wrong?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed | 2 months and 28 days old | 1lb

My kitten is 9 weeks old and has been having diarrhea that is neon yellow. It seems like it just seeps out of her at times as well. Idk what to do? I have 3 other kittens that are doing just fine. She is eating. But I usually take her to where she goes to eat. She has been laying around not really playing like she used to I've had to give her a few baths yesterday when this all began.

She is cute! She could have an infection or a parasite. You could take a stool sample to your vet and have it tested for parasites. If she hasn't been dewormed then an intestinal parasite is a definite possibility and your vet can prescribe a dewormer. She might also need some fluids to prevent dehydration. You could also add a probiotic to her food and see if that helps. Hope she gets better soon!

    This sounds like she could be having a problem with her food or a viral infection She should be checked by your vet as it won’t take much to cause dehydration at her size. They can do a stool sample check to see if there are parasites and chexk for a viral infection such as panluekopenia which may require hospitalization. Withhold her food and water for 4-6 hours and give a small amount of Karonsyruo for her blood sugar
