Expand your ScatMat's area of coverage with the ScatMat Extension Mat. PowerPack not included. The Scat Mat is a touch sensitive training pad which says "No", when you can't. The Scat Mat quickly conditions pets to avoid prohibited areas with harmless, low-power electronic pulses similar to static electricity. Place the flexible vinyl Scat Mat in a room entrance, on your sofa, counter top or the hood of your car. The touch sensitive pad will silently protect prohibited areas from trespassers. When the scat mat is touched, the battery sends small pulses to the Scat Mat for 3 seconds. These surprising little 'zaps' quickly repel most cats & dogs who stay away after one or two exposures - even after the scat mat is removed. Use the Scat Mat to: Keep cats or dogs off furniture. Keep cats off your car. Keep cats out of plants. Stop cats or dogs from soiling in certain areas. Keep cats & dogs off your bed. Stop cats from scratching your carpet or furniture..
