Thanks for all the replies. The reason I switched in the first place is because my kitten has had soft stools for a couple months now.
He was eating Royal Canin, so I tried switching to Nuro Natural Choice. Didnt help at all.
Im pretty sure he doesnt have any parasites as Ive dewormed him about 3 times and given him meds for giardia about 3 times as well.
His last two stool samples that were sent to the lab came back negative.

So I have no clue what to do, I heard Innova was really good, so I decided to try it.
I went to a local pet store, but they only had Innova Evo, so I decided to try it out.
