Abstract: A device for delivering an electric discharge to pets coming into contact with or coming close to bait, having an electrically insulated housing, circuitry for generating a high voltage mounted within the housing, including a battery to feed itself, an electrode surrounds the periphery of the housing and connected to one pole of the high voltage circuitry, and a second electrode mounted on the top cover of the housing connecting the other pole of the high voltage circuitry to the bait so that the electric circuit between the first and second electrode may be closed by the pet.
