I have three cats, and our litter box situation was a NIGHTMARE because my older cat refused to share with the two kittens. I hated having to keep three litter boxes. But they have no trouble sharing the Cat Genie! They took to it right away. I put it in the laundry room, and shut the cats in over night. I haven't had a single issue! It really does stay clean... I don't have to touch anything nasty. All I have to do is Sprinkle some granules in occasionally, and enjoy a house that doesn't stink!
