I have a 8 month old neutered indoor only male kitten who has developed diarrhea with the consistency of water. It is kind of an orange/brown color and very smelly!!!! I am not sure if he has eaten something.. he has been on the same kind of food for a couple months and it was only a couple days ago I noticed soft stools and then today and last night water like diarrhea. He also appears to strain or at least straining when pooping after the liquid comes out. There is no other symptoms of illness with him. He has been eating and drinking (although today I am not sure what he has actually eaten as there is only dry food out and does not look like a lot is gone) but I have seen him drink water. He is still playful and active. and nose is cool to touch. No vomiting ( I wondered if he could have ingested something or have obstruction somewhere). I am gonna call my vet in the morning but what direction to go I have no idea other than he has foul smelling water diarrhea. Oh and food he will only eat Iams dry kitten food.. I have tried every type including wellness, nutro, etc. and he won't touch them. He does (although not for a couple days) eat moist canned food in a variety of brands incluiding felidae, nutro, wellness, etc.
