This is a self venting cat box I built. It has a bathroom fan inline; I tapped into the vent stack for the tub while I was remodeling the bathroom. I also did all the tilework and everything else. The box emits no smell, the hallway design down the side traps loose litter before the cats jump out, and keeps the dog from getting "treats". It was a blast to make!
