A litter box has a tray having a bottom and an outlet at one end of the tray and a sifting element disposed within the tray and having a screen portion and a solid portion, the screen portion being disposed at an angle, facing the outlet of the tray, of 90 degrees or less as measured from the bottom of the tray to the screen portion, and the solid portion extending from the screen portion to the outlet of the tray. The litter box may also have a base pivotably connected to the tray so that the tray can be lifted in a pivot motion relative to the base, a shutter, disposed at the outlet of the tray, the shutter being vertically slidable between a raised position and a lowered position, and a receptacle, mounted to the tray and adjacent to the shutter, and having an inlet arranged so that, when the shutter is in the raised position, the outlet of the tray and the inlet of the receptacle are blocked, and when the tray is pivoted, the shutter drops to the lowered position to allow passage from the outlet of the tray to the inlet of the receptacle.
