The Clean Step Litter Box by Petmate has a domed cover on it to give your cat privacy and a little bit more space while going to the bathroom. It also has a carbon filter included in it so that the air is a little bit fresher on the inside and outside of the box. The box also has a step-like ramp that catches litter on the way out to keep the litter in the box and not on your floors.
