Well i really wish that there was an attachment to keep it in place with the litterbox and then the catch does catch a good amount of litter but not all. Litter still gets around it on the floor. The other issue is the little opening on the bottom is not easy to empty out and there is literally no way to clean the inside of the catch and sometimes i think it can be smelly. I think you would be better off with an actual mat that can be cleaned.
