Hey there, my cat has had diarrhea for the past two days, tan in color, he makes it to the box alright, and its solid, but not formed. VERY stinky. Food hasnt changed since mid april, and he does not go outside ot get any unusual treats. Any ideas on what could be going on? Hes behaving normally.

Hi there! I'm sorry to hear that Towan has had diarrhea, but I'm glad to hear that he's acting normal. My first though is usually dietary indiscretion, but you mentioned that he hasn't had any food changes in several weeks. If he doesn't go outside, it's very unlikely that he's picked up any parasites, but it is a possibility that should be ruled out if the color and consistency doesn't go back to normal within the next couple days. Some viral infections can cause stool changes that simply go away on their own, and you may never know what caused it. Another consideration, which is much much more unlikely due to Towan's young age, is a liver problem. Chronic light colored, super smelly poo can be an indicator of an issue with the bile duct. I really don't think that this is the cause as Towan is so young, but I would do you a disservice not to mention it. Personally, I would bring Towan in to the vet for a quick exam and stool check, just to be on the safe side, especially if the stools don't go back to normal in the next day or so, or if any more symptoms develop (vomiting, lethargy, disinterest in food, etc). I would not give him anything over-the-counter as many human drugs are not safe for cats. Good luck, and I hope Towan gets back to normal soon!
