Abstract: A plastic retractable pavement marker/reflector having a base with a freely rotatable depressable cap projecting upwardly therefrom. A neoprene material or some other non-absorbent flexible material is used to fill the cavity inside the base, thereby keeping out debris and other substances to make sure the cap remains depressable. After being compressed by the depressable cap, the neoprene material expands back to its original size, thereby forcing the cap to return to its original position projecting upwardly from the base, again making the cap visible from all directions.

Abstract: An array of disposable mesh liner bags are removably attached to a rigid flat insert that is held in place with retainers in the bottom of a pet litter box. Each bag has a center mesh and peripheral draw string to lift each bag individually. Litter is sifted through the mesh and solid waste lifted out and tied up in the bag for disposal. A solid mesh bag at the bottom of the array lifts out all of the litter after the top bags have all been used. A removable lid with a peripheral rim holds down the bags overlapping a top ridge of the box walls. A center lid opening admits pets to use the litter box.
