I'm just curious. I was given my first littermaid as a gift, and I loved it! When it finally died, I bought another one, and now wish I could afford a second one! All my cats love them, and they sure make keeping the litter box clean and litter box odors down! I have a foster cat that will pee on the floor if his litter box isn't clean, so the Littermaid has been a life saver at our house!!!
