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!

Cheap for grain free products but my cats didn't enjoy much....
