Corn allergies are more common than you think. It counts toward the total protien so you find a lot of it in cat and dog foods, even though it's not very digestable protine. I think this is part of what's prompting the trend toward grain free foods. Chelsie was repeatedly scratching the side of her face raw. The cat sitter put her on a corn-free food just for convenince, and suprisingly her face healed. Then the sitter tried some corn based litter that she was given, and Chelsie broke out in full blown alergic dermatitus, which receded when she went back to clay litter. I've kept her on corn free food and she's still scratching, but not as much. Next, I'm going to try grain free.
As far as more frequent, smaller meals, it's probably more normal for them. Look at how their ancestors lived. How big a meal is a mouse? It would take several to fill them up, and they're not going to have back-to-back catches. That's why one tactic to keep house cats occupied is to hide bits of food around the house for them to "hunt". With Chelsie, I'm trying to keep her somewhat satisfied while not filling her up in the hopes that her stomach shrinks and she will be satisfied with less and stop binging.
