I've seen automated cat litter boxes, but none of them even came close to meeting my expectations until I purchased the CatGenie. This is the King, Queen, Prince and Princess of cat boxes. It is so nice not to have to worry about cleaning up after my two cats! And I had absolutely no problem transitioning. Took away their old box and put their new one in place and without hesitation they started using it. Freaked them out a little when they were in the room when it started cleaning, but they have gotten used to that now. Forewarning though, if your kitty's poo is a little too sticky and it doesn't flush before the dryer kicks on, be prepared to leave the house! It will bake that poo! My only complaint; the little pellets get everywhere! But it's better than litter!
