I have the BEST idea in my head. I was thinking of a way to keep the kittens from eating the cat food and the cats from eating the kitten food. I came up with a great idea but I am not technical enough to create it. As I was pondering it, I realized it would also work to assign multiple cats to their own litter box so you can more easily detect a problem with your kitties. Man, I wish I was technical enough to invent this myself. It is an awesome idea! More later.
