It's not my favorite litter box, especially for what it costs!  In the first place, the litter area is not big enough for all the space the litter box requires.  My cats stand on the steps to dig in the litter and then, because the space is so limited they usually leave without covering up their "usage".  In the 2nd place, it doesn't do a great job of containing the litter and the "steps"/walkway has to be vacuumed out.  You can't use a whisk broom on the steps because there is a raised ledge across the lower step so you can't sweep the litter out.  It's a little cumbersome getting the lid back on the box but I'm getting better at that.  I really don't think I will use it very long.  It's just not as space efficient as the usual litter boxes with lids.
