i received this litter box as a gift and let me tell you i absolutely loved it! its the best gift i ever recieved. i use tidy cats glade scented clumping litter and its darn perfect, the only problem i have is that that plastic gear to turn the box ended up stripping smh. my cats have a terrible habit of pushing the litter over the barrier onto the floor and that caused the bowl to get stuck for sometime before i noticed and had to take it apart to clean it completely. i do wish there was a full cover for it. aside from a plastic gear this product is great! i have however, spent sometime thinking of improvements for it. hah.
