First off this is a LARGE box, almost twice as big as the usual covered box. You need three or four feet to "roll" the box unless you want to do the partial-roll, slide-to-the-left, roll-some-more, repeat backwards to settle the litter . (oh my back!). The box is very flimsy so it flexes when you roll it. The latches are a total joke. After a weeks use of rolling, leaking, banging on the bottom a latch came loose and spilled the litter all over. My cat decided to go in only one place so after about two uses there was a football size litter ball stuck to the bottom, welded to the grate or firmly molded in one corner. If the ball did come loose the drawer couldn't be opened with the ball in it. I finally discarded the grate and top so I have a very expensive pan litter box.Reality check: If you have a cat you're going to scoop litter one way or the other.
