My cat is a Maine Coon mix (so i was told) and he has a sensitive tummy since he was a baby (he is 8 months old now) and USUALLY there is no issues since i switched his food to one with a pro biotic. However, from time to time he still gets random mushy poops and then they end up stuck in his bum fur. I'm sure he doesn't want to clean himself after.. Do all long hair cats get this problem because of the long fur? Should i just try to keep his fur trimmed in that area?
