We will never go back to regular litter again! This self cleaning litter box is wonderful. Set up was very easy. This litter box is a bit bigger than our old one but that wasn't a problem. It comes with an adapter so be sure to set up your litter box near an outlet. The litter is great. Its not smelly or messy. You write the date on the little cardboard box underneath and after a few weeks put the lid on and toss. There's a little sensor that knows when your cat uses the litter box so it will rake through. We absolutely love this for our home and will recommend to everyone with cats.
