Recently I ran across another good article on PetMD for food intolerance issues in cats, which you will find here.

One of the Pioneers who taught us about "gluten free" information was Dicke, whose paper is outlined in "GUT" showing that wheat, rye, and barley are the culprits. The grains involved in gluten sensitivity are also listed in the article "A Non-Human Primate Model for Gluten Sensitivity". If you do a search through the paper you will find NO reference to corn at all........
If you are looking for intolerance caused by corn, that would more likely be another common allergen called "fructose" that can cause a couple of digestive issues. One problem is malabsorption, and the other is fructose intolerance. This is an important differentiation as your pet may also have other sensitivities to ingredients such as molasses that can be learned about in the article called, "Metabolic effects of dietary fructose". To clear up the misunderstanding, here, Dicke obviously understood that the term "gluten" was a misnomer when it comes to "corn gluten meal", and one has to dig a little further into the ingredient list to find the problem such as a listing of just "corn" or "corn syrop" or "fructose" in any form. As I have stated on other sites, "corn gluten meal" is in actual fact a corn protein. The only possible connection I can make with corn gluten meal and an intolerant/allergic reaction would be if the milling process creating the corn gluten meal was defective and residue of fructose was still present. I would only expect this in a poor quality, (cheap), product. If I find science to suggest I am wrong in my beliefs, here, I will correct the information on this site.
One study that covers an ingredient I always look for in pet foods is "Diet and Large Intestinal Disease in Dogs and Cats". What I look for is either beet pulp or rice bran as an ingredient in pet foods, and this article helps explain why I would do this.
Please post your food suggestions here under comments, and possibly the reason why it works in your situation over other foods. Thanks for taking the time.
