Prescription Diet c/d-s was changed about five years ago to reduce the
fat levels. High levels of fat are one way to lower urine pH levels. The
problem was a whole lot of, Ahem shall we say "chunky" c/d kitties.
Corn is great carbohydrate. The carbohydrate fraction is as digestible
as any other grain and the protein fraction is the most digestible of any
grain. It contains 5 times the levels of Omega fatty acids as rice and is 20
times less likely to be an allergen than wheat.
Sometimes we forget that animals need the amino acids that proteins
provide, not the protein itself. Cats are obligate carnivores and therefore
require specific proteins to provide specific amino acids. That doesn't mean
they cannot utilize amino acids from carbohydrate sources like corn equally
as well. It just means they have to have a broader array of protein sources
to insure that the entire range of amino acids required by the cat are
present in quantity.
Another FLUTD diet you might try is Prescription Diet t/d. It is an
excellent struvite diet, keeps the teeth clean and is the best hairball diet
