Loose smelly poop often diarrhea

Hello,
I would like to get advice on an issue I been having with my kitty Oliver. For a week he has been having loose smelly stool. Often times he goes about three times a day and does a very small amount of formed but loose stool and in the end puddeny. I am concerned because he eats really good food Weruva and no dry food. He is acting normal with energy and loves to eat. So I am confused what is causing him to have this issue.

Sorry you are having this issue with Oliver. How old is he and how long has he been with you?

Have his stool tested for coccidia

I have had Oliver since he was a kitten. Now he is about 3 years old going on 4. Last night I gave him fortiflora and it made his still a little more firm. I really don't like to give him fortiflora because I feel it makes him extremely thirsty. Do you have a recommendation for a probiotic?

No I haven't tested him for that. If he continues like this I will have to take to the vet. He still has so much energy and like I said alway looking for food. That is why I am not that concerned.
