Ozzy was on Eden for about 6 months, but unfortunately we had to take him off it. He had constantly runny stools, and we decided that we were feeding him too much, so we cut the amount right down. His stools did become slightly firmer, but he lost weight and was constantly hungry - becoming a real pest whenever we tried to eat a meal. So we gradually increased the amount again, but his stools just got runny again. We came to the conclusion that it just didn't suit him. We changed to Wainwrights and he seemed much better, not hungry and firmer stools, but then he started to itch a lot (which is why we put him on Eden in the first place!) so we've swapped him to Wainwrights grain free and he seems to be okay on that at the moment. Eden is a really good food, and we were sorry it didn't suit him.
