I have litter trained both my babies (Roscoe & Lexie). Some days they will knock it out of the box and scatter it and some days they don't. It can be messy at times. But, we liked this much better than the pads. I have 2 of the mid size boxes and 1 of the large boxes. The small size is fine for my Lexie (about 5 lbs), but Roscoe needs the large one (he's 9 lbs) so that when he does his business, it doesn't go over the sides onto the floor!!
