Ok, thanks everybody! I had always read that you should have 1 litterbox for each cat that you have and I guess I thought that meant it was because they only want to use their OWN litterbox. I've never had more than 1 cat at a time so this is all new to me.

I will have to stop free feeding the kitties I guess and just give them breakfast and dinner so that they each get the right food. Molly can't afford to put on any more weight and Ozzie needs that baby nutrition. Molly's gonna be PI$$ED! LOL
