The High Tech Pet Products Radio Mat Kit features an electronic scat pad that sends stimuli to your dog's receiver collar whenever he touches the pad. Use it to keep your dog away from the trash or off of furniture. At the touch of a mischievous paw, the pad sends a radio signal to the included collar to emit a harmless but unpleasant shock. The pad can also be turned to Sound Blast mode, in which the pad itself emits a loud sonic blast when touched. Kit includes pad, collar, and collar battery. Scat pad battery not included.
