Had one. Sold it after 3 months. My male cat was about 6 months old having no litter box issues, then we bought the Genie, and that is when he started peeing elsewhere. He didn't like the Genie. It might work for a brand new kitten that you could get used to it though. Concept was good but if poo ever got caught without getting sifted out before the heated wash cycle and dry cycle began, your whole and I mean whole entire house will smell of HOT POO. Poo is bad enough but HOT, Burning Poo is intolerable... I usually had to go ahead and scoop all the poo before the cleaning cycle to prevent this which kindof defeated the purpose of the machine itself. The pellets track worse than regular litter. The freshness every night was nice though. Definantly wouldn't recommend for more than one cat. It is very small, but takes up more room than a normal litter box. Just My Opinion.. Hope that is helpful.
