The Sofa Scram is a product that was developed as much by our customers as by us. Back in the 1990s we began getting countless requests from consumers for a "SCAT MAT" type of device that didn't use shock. After all, being the leaders in sonic pet training, our customers expected that we should have such a device, and we agreed. In creating the product, the behavioral science was pretty easy. Just blast the pet with enough irritating sound to make the floor a bit more appealing than the couch. The mechanical design was the challange. We needed a clever idea to create a soft, paw activated pad. Of course, our ingenious engineers (as they constantly remind us) were happy to oblige. They created a flexible, pressure sensitive material that acts as a continuous switch, controlling the same speaker we use on our Sound Barrier and Yard Barrier products. Our designers covered the device with mountaineering grade pack cloth to create a beautiful, rugged and absolutely annoying pet scram mat. Instantly activated by the touch of a paw, the battery operated Sofa Scram emits startling 85 decibel beeps that get pets off the furniture fast! This item has been a best seller for the past fifteen years! Pet owners love the Sofa Scram because it works quickly and effectively without applying shock or pain to your pet. Compare to "Scat Mat" type items selling for as much as $80.00. The Sofa Scram works just as effectively, just as quickly, does not hurt your pet and it sells for about half the price! MEASUREMENTS: 12"W, 58"L, 2 1/2"H.
