Frequent, well-formed bowel movements from 6 month-old kitten . . . is this normal?

I recently took in a semi-feral kitten who was treated about three weeks ago for intestinal roundworms.  He is using his litter box beautifully (such a good boy!), but I am noticing that he has on average about four well-formed bowel movements per day.  This seems pretty excessive.  His stools often have a pungent odor, as well.  No diarrhea or soft stools, though.  I had a stool sample re-checked for parasites last week, and that came back negative, so it seems like parasites are not the issue. 

Is it normal for a young cat to have such frequent bowel movements?  He is on a grain-free Wellness kitten diet of mostly canned food (two small cans per day), with some dry Wellness kitten food also to supplement (about 1/2 cup per day, sometimes a little more).  He always drinks a lot of water as well.  Does this sound like it could be a food allergy/sensitivity issue?  He does have feline herpes and some other health issues courtesy of being born in filth and weaned too early, but his energy is very high and he seems to feel good most of the time, w/ no obvious signs of gastrointestinal distress (aside from occasional stinky gas if he eats any "people" food).  I just wonder if his poor little immune system is hypersensitive b/c of his history (?), or if I am worrying over nothing.

Any thoughts appreciated!  Thanks. 

I was going to suggest grain free food but you've got that covered (good for you!)

So it may be a sensitivity issue, although as long as his stool is well formed and he's using his box, I wouldn't worry too much.  Like people, cats have different systems.  Some people go more frequently than others.  He may just need to empty himself out more often.

If he develops other symptoms, though, I'd have a talk with the vet about it.

Kittens have a high metabolism rate so they eat more and eliminate more frequently than adults. I'd say your little guy is just fine.
