ABSTRACT:
A pet waste material collector and odor eliminator system having in combination a rectangular container, a removable tray insertable in said container which holds litter material and has vents disposed around the upper vertical portions thereof, a filter pack, a fragrance dispenser, and a fan. The tray forms an air chamber between the bottom of the container and the bottom and sides of the removable tray. The fan pulls air and odors across the litter bed material, through the vents of the removable tray into the air chamber, through the air chamber and through a filter pack which absorbs and/or adsorbs the odors. The air is then pulled across an optional fragrance dispenser which masks any residual odors. The litter box also has a motion sensor device which automatically shuts off the fan as the pet approaches the litter box usually about 10 feet from the litter box.
