I have to admit I was skeptical at first having read some awful reviews of self-cleaning litter boxes in the past. That said, I’ve been using this box for two weeks and so far so good! It is roomy enough for my big cat, relatively quiet, and does a good job at what it claims to do. There was no “transition period” for my cat as he immediately took to it like any other litter box, but he’s pretty easygoing anyway. I’m ecstatic about not having to deal with “litter dust” like I did with traditional litter. That stuff would get everywhere! The one thing that would make this product even better is if there was a way to make it battery operated so that it could be placed ANYWHERE in the house instead of limited to a space right next to an outlet.
