My cat is a notorious litter kicker, but this top-entry box has completely stopped the mess—the deep pan holds plenty of litter and the included scoop is a nice bonus.
The lid holes actually do catch a lot of the tracked litter, so I'm sweeping way less than with our old open pan. My chunky 14-pound boy figured out the top entry within two days, and the deep pan keeps him from peeing over the edge. Scoop that came with it is flimsy but whatever, it works.
Wasn't sure my cat would use a top entry box but she figured it out in a couple days. The little holes in the lid really do cut down on the litter she tracks across the floor, though I still find some near the box. The scoop that came with it is decent too.
