I just don't know what to say - THE CAT GENIE IS AWESOME!!!!! We have one very LARGE male cat named Max and until I ordered the Cat Genie my house smelled like poop. I was so ashamed when visitors came I wouldn't answer the door. Cat Genie works like a dream. I have had it about 3 months and have had no problems. Max took to it with no problems or accidents. I am going to order another one for my mom today.
