Pet Trainer Alarm

Your dog and cat will soon learn where they don't belong, even when you're not home! Simply place this 4-1⁄2"x2"x1-1⁄2" Pet Trainer unit on your couch or easy chair. When it senses any vibration, a loud, two-second alarm scares Rover or Fifi away, to keep furniture free of pet hair, stains, rips and scratches. Resets itself, and sounds the alarm again, until vibration stops. Add a string and you can hang it on a hotel-room doorknob, or on a medicine-cabinet knob. High/low sensitivity switch. 9v battery included.
