I have been wanting one of these for a long time but never had the room. We bought a new house and I measured out a spot for it right away. I ordered the week we moved in and once I got it I set it up. I didn't want cat litter dust in my new house. It was easy to set up, instructions very readable. I let the 3 cats use their old box and explore the catgenie for 2 days but then just took the old box away. They've been using the catgenie wonderfully and I love it! No litter dust, scooping, or taking heavy bags to the trash!
