The neatest thing for cat owners that hate to clean cat litter up is an automatic litter box called the CatGenie. It eliminates the need to buy cat litter because it uses CatGenie washable granules and CatGenie Sanisolution to wash and flush away cat poop. The granules replace the regular litter and the sanitizing solution washes them and the unit.

Sometimes the solution is called CatGenie cartridges because the solution is in a replaceable cartridge. Even though you do need to replace the cartridges about every 2 months it is still cheaper than buying cat litter and less work too.
