My 5-month-old kitten won't eat, play, or poop. When should I worry?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | neutered | 5 months and 10 days old

My 5 month old kitten hasn’t had very much appetite since Monday which is not usual. Usually he finishes all of his food everyday. I gave him wet can food which he ate most of when I sat with him and made him eat. He also hasn’t been as active as usual playing less. He went poop once on Sunday night and not again until Tuesday night. Should I be concerned or can this maybe just be upset stomach?

Hi there, and thanks for your question on Petco Pet Education Center, formerly Petcoach. A decreased appetite in a young cat who's usually a good eater is definitely cause for concern. Although it's not a very specific symptom, appetite tells us a lot about how our pets are feeling, and since the decreased appetite has been going on more than 24 hours, it's time for Cash to see the vet. Hope this helps and he feels better soon!

    Thank you for submitting your question regarding Oreo. I recommend that he sees a veterinarian. His symptoms are worrisome for a young kitten. He should be very playful, not sleeping a lot at this age. He needs to be seen to determine that cause of his illness. Then treatment can be started to help him feel better. I hope this information helps!
