Poor Quality, doesn't stop litter very well, stinks!
While this does grab litter from the cats paws it certainly doesn't grab enough of it. We have 3 of them in a row on the floor and even after going over 3 of them there's still lots of litter scattered throughout the house.
Also, they smell like weed, even after washing them out and leaving them outside for a couple of days the smell is still there.
I don't know what planet the other reviewers were on, but these really suck.
