This has been so amazing. I didn’t think my cats would use it but they used it right away. I was so happy. It is a great idea!! Litter is contained! I have tried to many other things. Even litter box enclosures but one cat would end up peeing inside and not the litter box. This is perfect. Even if he marks while inside it’s the actual box and not a particle board enclosure that I had to end up throwing out. I wish the outside was “prettier” since I have it in a visible area but I can deal with it!
