A self-grooming tool for mammals consists of a
quadrilateral pad which has a front face having a plurality of teeth extending therefrom, a rear face and opposed
peripheral end and side walls, the opposed
peripheral walls having complementary configurations. A recess in the rear face defines two planar areas, the pad being foldable about the recess between a flat position and a folded position. One each of the
peripheral end and side walls have laterally projecting flanges, the underside of each
flange being co-planar with the rear face of the pad and the flanges having a thickness which is less than about one-half the thickness of the pad. The other of each of the peripheral end and side walls have lengthwise extending undercuts formed therein, having the same shape and dimensions as the flanges, and communicating with the rear face of the pad.
