Abstract: A kitty litter disposal device for hygienically reusing kitty litter in a litter box has a plurality of fine-meshed nets in juxtaposition with the bottom of the litter box in the box. Each net covers the bottom of the litter box and extends along the inside surfaces of the sides of the litter box, over the lip of the litter box and along at least part of the outside surfaces of the sides. Net fasteners in the nets and on selected sides of the litter box releasably fasten the nets in position in the box, whereby kitty litter in the litter box on the nets is siftable via the uppermost of the nets upon unfastening of the uppermost of the nets and manual holding of same in the box at a distance above the remaining ones of the nets thereby to pass the kitty litter into the box.
