Hello! In a kitten that seems to be otherwise healthy I think about intestinal parasites as a top diffrential. Casey should definitely be seen by a veterinarian as long term diarrhea can lead to dehydration. The vet will also be able to have the stool tested for intestinal parasites as well as treat Casey with the appropriate medications. Even if he tests negative for parasites, he could definitely benefit from medications to treat his symptoms and possibly some fluids to help rehydrate him. Hopefully this was somewhat helpful. Best of luck to you and Casey.

    They commonly develop some infections in their intestine at this age, or just have an imbalance of their normal gut flora (bacteria). This particular diarrhea is rather mild and it's a good sign if it's not affecting his energy levels. Most diarrhea will resolve within 3 days, so it's OK to wait a day or two and see if it resolves on its own. In the meantime, you can start giving a bland diet and add probiotics (can get this at the pet store) to the diet. Have a read of this short article about resolving diarrhea at home for more help: https://www.petcoach.co/article/6-things-you-can-do-at-home-if-your-pet-has-diarrhea/ If the diarrhea persists for another two days, then it's best to get him checked by a veterinarian, because he may need medication. Also, take him to the vet if his energy levels decrease or you start to see blood in the diarrhea. I hope that helps and Casey gets better soon.

    It sounds like your cat has a severe case of colitis, or an inflammation of the colon. Colitis can be caused by many different things. Some of the more common causes include intestinal parasites, dietary indiscretion, food intolerance, irritable bowel disease, pancreatitis and viruses. Since Casey has had diarrhea for over 48 hours I would recommend taking him in to the vet to be examined. He may need fluids to correct any dehydration, a fecal examination performed and antibiotics and/or probiotics to help the diarrhea clear up. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.
