This Cat Box is the Cat's Meow, best thing since sliced bread! No more scooping, it automatically scoops itself after each use. It minimizes litter box odor. It is slightly used (we have two but only need one) - but it is clean and in new condition. Yes, it seems expensive, a brand new unit cost $700, but once you and your cat use it you will ask, where has this been all my life. We have two cats and they enjoy watching ours automatically scoop itself. It is WIFY enabled, you can sync it with your phone with the Whiskers app and monitor its use, and tells you when the bag of litter needs to be changed. You do not have to scoop, just pick up the bag of litter from the drawer below the unit and place it in the trash and install a new bag. The app tells you the litter box status, when litter needs to be added, cleaning cycles per day and week and your cat's weight each time it is used. See the following for more information.
