Product review (3 stars): kitty litter tray? probably not.
I'd give this more stars if I were using this for its intended purpose and to set it and forget it, but I purchased it as a cat litter tray so will be handling and cleaning it from time-to-time. I currently have the litter tray on a chair mat in the basement and the kitty would occasionally miss so I'd have to clean up the runoff from the basement floor.
For my purposes the plastic is thinner than hoped. The rim gives it rigidity but the sides and bottom are only slightly thicker than that of a plastic welch juice container. I may coat at least the sides with some polyurethane or something else with not too much weight, but provide some more reinforcement. As is, I expect it to crack at some point. Anyway my review is probably not fair because I'm not using it under a washing machine, but thought I'd leave this for anyone else looking for a solution to cats making a mess. I am glad I purchased this at a discount on Amazon warehouse.
