Abstract: Disclosed is a pet grooming and pest killing device that comprises a handled comb having a working end comprising a plurality of comb tooth electrodes powered by a battery power supply within the handle of the device. The comb teeth employ an alternating configuration wherein adjacent teeth employ opposing polarity and the tips of the teeth are shrouded by a protective insulator. The spacing of the teeth is such that a tick or flea will become trapped between two teeth, allowing current to flow from one electrode to another through the pest and thus killing it upon contact. The ends of the teeth are insulated to prevent shocking of the pet during the combing process. In this way, pet hair can be tended to while also killing loose ticks, fleas and other pests within the pet's hair while grooming.
