When I learned I have Celiac Disease, I also looked at my cats. I looked at their foods and all the garbage fillers there are in their foods!!  The grains and fillers cause cats to get fat, and later when animals get older, it can give them Diabetes also. It's just not good for them. I use HALO pet foods for my cat. They don't have corn, wheats or glutens. They have Cat and Dog foods here!Smile
