I have seen the ads, but I have not tried it yet. I intended to, although I have had great luck with the Tidy Cat Multiple Cat clay litter for controlling odor. I use a big garbage bag for a liner with the clay litter and then discard bag and all. I don't like to spend time "scooping." As for the additional garbage in the landfill, I recycle and try to make up for it in other ways. Sandy
