Been using CatGenie and buying CatGenie supplies since 2010 or 2011. Products cannot be beaten. The CatGenie itself is the best cat box EVER! No dust! No scooping! No bad smells. Set the auto clean feature and, in our case, the box cleans itself 10 minutes after the cat is finished using it! All YOU have to do is flush the toilet!!! Every so often you run the cleaning solution cartridge, which you never have to touch except to insert the cartridge itself, and the box is cleaned of scale from the water and any build up that might have accrued. People are amazed when they walk into the house and finally realize we have a cat because there is absolutely no smell or hint of a cat box EVER!
