If your cat has diarrhea something is going on. I would change the food first off to see if that helped the situation. You need to be on top of this as they can get dehydrated very quickly. Without more to go on it is a little difficult to make suggestions. What is going on in the household? Is it stressful? Are there other cats?
Have you changed the food recently? Is he drinking water?
