She would happily live on Gourmet day and night - gave her some last week before lesions came back up, to see if she liked it. She LOVED it, but it is full of cereal, which is a common cause of food intolerance in cats. When my last cat got IBD, I did so much research to try and find a solution as none of the meds, prescription diets etc were working and she was literally at deaths doorstep. After trying absolutely everything for months on end, eventually put her on a raw diet and within 2 days the vomiting cleared and she was full of life again. I kept her on high protein cereal free commercial food forever after then and she never relapsed.
Cats systems aren't designed to digest carbs. Lots of vets now think it's the high carb content of most commercial food that's leading to many of the illnesses in cats, including allergies.
