I had a cat genie for years and then moved out on my own and couldn't afford one. Now that I have my own again I can't imagine going back to a regular litter box. I just wish the supplies weren't so expensive. 1 box of granules definitely doesn't last 3 months like the site suggests. I only have 1 cat and we probably go through a box every month and a half. I love the fresh scent, though.
