  • Cat litter box assembly having a cover and a retractable hood
    Patent number: 5572950
    Abstract: A cat litter box assembly comprises a rectangular litter box tray, an upstanding cover removably securable on the walls of the tray so as to extend over and about a portion of the tray rearwardly of the front wall thereof, and a removable hood pivotally mountable on the cover between an extended position and a retracted position. The hood defines an elongated forward edge portion which, when the hood is in the extended position is disposed forwardly of and above the front wall of the tray and cooperates therewith to define an elongated cat entry area therebetween extending substantially the length of the front wall of the litter tray. The front and rear litter tray walls are longer than the side walls, maximizing the width of the cat entry area for the size of the tray. In the retracted position the hood is disposed interiorally of the cover and in substantial juxtaposition therewith so as to provide unobstructed access to the interior of the litter box tray for viewing and litter cleaning.
