Query: Lazy cat owner's dream

We had an electric self-cleaning box before this one, but it shorted out after a couple weeks, and didn't work well to begin with. Then we ordered this box, and though it takes some getting used to, it's the best box we could hope for, at a reasonable price. Really easy to clean. Despite its high wall, the cats DO manage to kick some litter outside the box, but certainly a smaller amount than most litter boxes.I've found that crystal litter works very well to supplement this box for a lazy cat owner such as myself. It sifts through the box's grating as well as normal clumping litter, if not better, and you don't have to change it nearly as often.
