Thanks for using Petco Pet Education Center, formerly Petcoach! Diarrhea can be observed with conditions such as colitis, gastroenteritis, dietary indiscretion, intestinal parasites, among many other possibilities. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. They may choose to check for parasites and to start medications for diarrhea depending on the results. Good luck! Hoping for a speedy recovery!

    If he vomits again and/or the diarrhea continues, I recommend getting him seen by your vet for an exam and lab work. It may just be a passing episode of gi upset, but if he stops eating or becomes lethargic, get him seen right away as this may indicate some underlying problem.

    The blood is concerning, which makes me think maybe he ate something he shouldn't have that might have injured his intestinal tract. The fact that he seems fine otherwise is good news, but I recommend getting him seen by your vet for an exam to be safe.

    Situations such as abrupt change in diet such as kittens starting new food, a stressful situation (new environment) may cause a kitten to experience a brief episode of diarrhea. Diarrhea can be transient, short and readily treatable condition. I wouldn’t be too concern as long as he is eating, drinking, behaving normally and no vomiting. I would worm the cat at least twice 2 weeks apart and watch him carefully for the signs above in the next 1-2 days. If diarrhea persist beyond or the kitten stops eating/reduced activity/vomiting start please take him to a vet.
