I ordered these for the price, and they seemed very nice. But when I received and started using them, I realized these are possibly the worst litter boxes I have ever owned.  I don’t know who decided to put a curve in the bottom part of the litter box, but they are extremely hard to clean!  If you’re like me and need to scrape the bottom of the litter box on occasion, these are not very good. The curved bottom makes it almost impossible to scrape with your scope. I would not recommend buying these at all.￼
