I get soooo tired of cleaning up litter off the floor. Have tried grid pieces and litter pads to put under the litter boxes to not have litter tracked through the house, but then have to clean the litter off the pads and grids that does catch most or some of the litter (not all). Haven’t had to worry about little boy urine… which I would think this would work well also. I wish I would have used this from the start, as our 2 kitties are not transferring over too well from their previous one. We have both out and sometimes they use this one but mostly use the regular one. Probably different story if they weren’t 12 years old set in their ways- but not giving up.
