Great capacity with high sides-I wanted a leakproof option for accidental overspill, and this one fits the bill. My only gripe is that the plastic is a little flimsy if the box is full of litter and you lift it a certain way. It will bend and stress the plastic (evident by the whitening of the bentstressed part of the plastic). One of the better boxes that you can buy!

This is a great litterbox . Having a closed lid helps keep the area around it clean.
