4 Pack CatGenie Machine Maintenance Packs- Works in both CatGenie Models
Product Review (submitted on December 20, 2017):
I hesitated to order these, thinking that the cartridges would be enough. About once a month (I have two cats), I use these granules to really sanitize the CatGenie. They do a very nice job of getting the hopper area clean and sanitized. I wish I had ordered these the first time that I saw them. I've had my CatGenie for more than two years and I LOVE IT!
