This is a Must Have for Cat(s)
I have used this litter box with one cat, two cats, and even three cats. With three cats it needs to be cleaned a lot, but for one cat, it is just about as easy as life can get with an indoor cat. My favorite thing about it is I can go out of town for 2-3 days and the litter box is fresh for my cat the entire time I'm gone. I use Tidy Cats brand and it works perfect (and I've been using it in the Littermaid for years). I tried the Littermaid brand of litter that was recommended once and it was the most awful stuff I have ever seen. It attracted gnats or flies (can't remember, I just know it attracted some insect!), smelled, and did not clump. Just buy Tidy Cats, it works just perfect. Tuck a grocery bag into the box that catches the litter and tuck the bag around the top before you set it in place. This makes clean-up super easy, and it makes the "disposable" boxes last longer. Cleaning is not bad or as gross as it seems - unscrew the teeth, dump them in hot, soapy water, and rinse. Wipe everything else down, just like you have to do with a regular litter box. Be careful to not get water in the track - there is a sensor in there and I had a friend "clean" the box for me and he got water on the sensor, which killed it. I had to buy another one and it has worked flawlessly for a few years now.
