Bought a new litter box for the boyz. The big advantage is the entryway is a series of steps and the litter is located on the side of the steps. This greatly reduces the amount of litter that gets tracked outside of the box. Thompson took one look at it and looked back at me as if to say, "You expect me to do my business in a space ship?" Alas, I think all three boyz have tried it out with no problems.
