My two cats have been on this for a couple of years now. Unfortunately both of them seem to have developed an intolerance to an ingredient in it - just one mouthful is enough to make one of them projectile vomit minutes later and the other produces bloody, liquid stools. Just a few days after changing their food and they had normal tummies. I tested my theory by giving them Porta 21 again yesterday and hey presto, we had two very ill cats on our hands!
