DVPETS Open-Top Automatic Self-Cleaning Multi-Cat Litter Box, 21.6-in

I needed a box that would fit the bottom of my laundry room shelves. This box seemed to be perfect for our needs. The delivery day changed three times, but only three days late was acceptable. The Fed-Ex driver left it in front of the garage rather than at the front door. Fortunately, I have a dolly to move big, heavy things around, and I got it through the cars and into the house. Unpacking was easy. It arrived all set up and ready to go. Got it in place quickly as Sunny decided he needed to use it I'mmediately. As he was climbing in, I was madly pouring in the litter. Out he came, then I waited. I put away the food part of my Chewy order, still waiting. I wanted to see it do its thing, but I have little patience, so missed the performance. Later, I looked in the waste receptacle, and, sure enough, there was the clump. It worked! I walked in this morning a week later, to catch it doing its thing...silently, perfectly. It dumped the clump and straightened the litter so that it was absolutely level. I had come in to change the bag. It was so easy. Just pulled the bag handles out, tied them up, and put in a new bag. That was it. Done. See you in a week! Boy, have potty boxes changed. To me, it looks like a space capsule, it's lights blinking, ready for liftoff. Sunny and I are both very happy with our new catbox.
