I would love to use something other than the clay litter that I'm using now. The cats were using Worlds Best and I had problems with one of the cats eating it. He had chronic diarrhea because of it. He is probably allergic to corn. They don't eat the clay litter so I'm going to stick with it even though I would rather use something else. I'm afraid that he'll eat the wheat litter too. Anything that smells even remotely like food, he will eat!
