Abstract: An improved automated litter box comprises a motorized comb or rake drive mechanism for removing clumps, a means for cycling the drive mechanism, and a cat proximity sensor for sensing the relative position of a cat about or within said litter chamber. The cat proximity sensor is capable of identifying the location of a cat outside the litter box or litter box or litter chamber. The cat proximity sensor comprises a passive or inductive transmitter for identification for modulating and demodulating a radio frequency (RF) signal; and an antenna for receiving and transmitting a radio frequency (RF) signal.

Abstract: An improved apparatus for grooming animals, particularly for the removal of loose hair and hair that is soon to become loose. In a first embodiment, a base has one or more slots that slideably receive a corresponding number of comb extensions. The comb extensions are transversely disposed relative to a longitudinal axis of the base, are longitudinally spaced apart from one another, and are oriented at a common angle relative to the base. In a second embodiment, plural rows of transversely disposed tines are integrally formed with the base. In a third embodiment, the base and comb extensions are integrally formed with one another and the base is snap-fittingly engaged to a clip member having a handle that is integrally formed with it. Further embodiments include plural base sections that interlock with one another or which are interlocked together by a separate locking member to collectively form a base, wherein each base section carries a row of tines.

Abstract: An improved tool for grooming pets, especially for the removal of loose hair and hair that is soon to become loose, comprised of a base (10) with comb extensions (12,14) mounted on either side at an angle of less than 90 degrees to the base. The comb extensions (12,14) are comprised of tines extending from a solid backbone or shoulder (16) that protrudes from the base (10). The comb extensions (12) on one side of the base have tines that are larger and spaced further apart than the tines of the comb extensions (14) on the other side of the base. A cleaning tool (18) comprised of a base (20) with tines (22) protruding therefrom is held in a compartment (24) on the side of the invention when not in use. As the invention is stroked through the hair of the animal, the angle of the comb extensions (12,14) causes a deep and prolonged penetration of the coat.
