There is nothing more enticing to a cat than a forbidden counter top, or a couch to a dog where he is not allowed to sit. The Tattle Tale Training alarm features a vibration sensor that will emit a two-second beep if the alarm is jostled. It can also be hung on a door or a piece of furniture, and features “high” or “low” setting so you can get the sensitivity right.
