I have a 20-lb. Maine Coon cat and I hate heavy-duty maintenance chores. I tried almost every type of litter box on the market, and I stopped here. Yes, it gets stuck occasionally - large cat=large messes. But this is the best I've found of the electronic boxes, and the ability to use any plastic bags to line the container saves a lot of money compared to using the other ones. (I used Littermaid for years with a smaller cat and had to replace them too often.) Since my cat has a sensitive stomach also, I paired the box with the Fresh Step Extreme Odor Control litter - wonderful. I highly recommend this.Fresh Step Extreme Odor Control Scoopable Clumping Cat Litter
