Here's everything you need for one cat for almost a year. I didn't think I would need the granules, but ordered this package anyway. Even sweeping the tracked granules up and dumping them back in the Cat Genie, I've used most of the box this year.
The fresh scent of the maintenance cartridge is very pleasant and very refreshing - one of my neighbors liked it so well, she asked me for the brand name of my air freshener. The light scent dissipates very quickly as well.
