After trying every automatic litter box on the market including the disaster, CatGenie, I have settled on the Scoop Free. I finally threw away my CatGenie and all unused cartridges and plastic litter after a 2.5 year struggle to get it to work. Since I never got it to work, my cats refused to use it and would crap just about anywhere rather than step into it. They were traumatized by its constant beeping because the Cat Genie refused to recognize a new, full cartridge or by its too frequent tendency to not drain properly when it actually recognized a full cartridge and "operated".

Anyway, back to the topic I began with, I tried the Scoop Free Litter Box system for 1 month and both I and my cats love it! So, to make it more economical to use, I have purchased the Forever Tray and I would like to not have to wash it - so I want to use it with a liner. Does anyone have a liner they want to recommend to use with it that preserves the effortless nature of the Scoop Free Litter Box system?
