CatGenie 120 SaniSolution SmartCartridge (Fresh Scent, 6-Pack)

These SaniSolution packs are a must for any cat genie owner. They come in unscented or "fresh scent". I've tried both and found that the fresh scent seems to work a lot better in terms of covering up the "baked poop" smell during the drying cycle. We have 2 cats and on the cat activation cycle, one cartridge seems to last around 2 months or so.My only qualm with these are the price .... Also the cat genie hand doesn't seem to get clean with this solution and I have to manually wash it almost every other day. But, all in all, it's convenient and a lot more sanitary than a litter box.
