I purchased my first Cat Genie in February of 2012 when I purchased my current home. With two really big cats using it, that particular unit lasted until about 3-4 months ago & it finally gave out.
Afterward, we returned to a regular liter box with normal cat liter for the last 3-4 months. Needless to say, it has been the WORST 3-4 months you could image!! We have not been able to control the odors, no matter what "deodorizing" products we purchased. (And who wants to clean a liter box!? Eewww!!!)
Anyway, I am now anxiously awaiting the arrival of my new unit any day now!! Therefore, I am saying, if you are on the fence about making a purchase, DO NOT debate any longer! Buy one - you will NOT regret one penny spent! I haven't! And don't forget to get the package deal - the supplies are more costly if you have to ship them one by one, so make sure you join the VIC club!
