Query: Great Idea!

The CatGenie is an ingenious invention. It is easy to hook up and maintain. Our 15 year-old cat has no problem using it, and since we previously owned an automatic scooping litter box, the CatGenie did not scare her. The plastic pellets do scatter, but so far, that is the only down side to this product. We love the fact that we don't have to deal with cat feces-EVER!
