The Never Miss litter box is a litter box that is designed to keep the mess out of the way the Never Miss litter box has high walls that is also designed to make your cat turn to the side so that they wont kick out the litter and also so if your cat goes to the bath room there is no chance of them missing the litter box! I also think that it is great for those bigger cats! We tested this out with kittens and with a adult cat and I find that it works better for the bigger cat then the kittens just because the high walls where kind of hard for the kittens to jump in and out! but I love it for the bigger cats!
