Abstract:

An automated cat litter disposal system for a cat litter box having a floor, upstanding side walls and end walls. A set of parallel tracks extend along the side walls. The tracks include lower sections extending from one end wall, upright sections rising from the lower sections proximate to the other end wall, and upper sections extending between the upright sections and the second end wall. A rigid scoop extends across the width of the cat litter box and is mounted by track followers to move along the track. The scoop has a lever mechanism which bears against the scoop guide that follows the course of the tracks. An electric motor drives the scoop along the tracks with the scoop lever bearing against the scoop guide. The scoop is thereby held in an orientation to scrape the floor of the cat litter box to lift scrapings from the floor as it moves through the transition between the lower track section and the upright section, and dumps the floor scrapings over the second end wall at the end of the upper track section.
