Query: Don't Buy It!

This is a terrible product that both you and your cat will hate. They claim that you will only need to change the litter box once a month but that claim is 100% false and they know it. Checkout their website where you will see that they offer standing monthly orders of four packs or six packs of the cartridges. If each cartridge lasts a month why would anyone need four or six a month? They barely last three days and at the end of the three days your cat's paws will be soaking when he/she steps out, your house will smell, and you will realize that you have been ripped off.
