Where else can you get another toilet in your house for under $300.00? Now I ask you? Our first control unit developed some problems. Cat Genie shipped us a new one in 48 hours or less. Works perfect, love it , cats love it. We have an odor free home and no more scooping, washing out the box or schlepping smelly litter to the curb.Buy one and never handle dirty litter again. Do it!
