I was literally at my wits end trying to figure out what do do about my litter situation. I'd tried all kinds of different litters before I came to the realization that it might not be the litter so much as the cat box I was using. I love the filters in the top and the locking top! This box keeps litter out of my floor and odors out of my house. I use it in conjunction with Tidy Cats- Multiple Cats litter and I actually invited someone to sniff out the box today, haha. They were absolutely amazed that they couldn't detect even the faintest smell. You can't even smell the scent of the litter! I would highly recommend this box to anyone with a cat!
