Every time someone visits my apartment they always marvel at how they could never tell I had a cat if there had not been an orange ball of spiteful fur jumping off my dining table. My friends are always surprised at how they cant smell his litter box whatsoever regardless of it being adjacent to the front door. The cat has no issue using it, and it clumps very well. I've never noticed any dust and a good 40lb bag can last me up to 3 months.
