This product is wonderful!!! I love the fact that I don't have to scoop litter, but the box is always clean. I love the fact that I am not lugging huge tubs of litter up two flights of stairs. I love the fact, that when I'm on vacation, the cat sitter only has to worry about the food and water. What a feeling of freedom. I am no longer slave to a litter box!!! I recommend this cat box to everyone I know that has cats. Unfortunately, the initial investment is fairly cost prohibitive for most of the people I know but even with the cost, it was completely worth it!
