Abstract: Pet Bed with a tray member having rigid side walls and a flat D shaped bottom. The tray member contains a downwardly disposed rotator post attached to its underside. A support tube accepts the rotator post. A horizontal base having an integral upwardly disposed vertical socket retains the tube. The tray has a horizontally disposed plate extending from the straight side of the D shape and is capable of being inserted between the mattress and box spring of a standard person's bed. A cloth covered foam insert lines the inside walls and floor of the tray. A flat heating pad is placed between the tray base and the underside of the poly foam insert. The rotator post has a flange at its upper most portion. The rotator post is capable of rotating within the support tube so that the attached tray can swing out and away from a person's bed.
