I can understand your not wanting the less fortunate to go hungry, but this is not food-grade corn we're talking about, as
niccoli pointed out. It's not as if World's Best Cat Litter is raiding the same corn supply as Green Giant in an effort to make a better, kinder cat litter.
A different thought: why is it so bad that someone has looked at the properties of an item, seen it to be a better product than what we currently have, and tried to market it? I don't care if it's corn as cat litter, pumice stones as pencil filling, silicone as breast tissue (
). If a dog is better at being a chicken than a chicken is, why not give it a shot?
