The Stay! Mat works by detecting the pet’s weight on the mat. If the pet leaves the mat, it will send out a radio signal up to 6 feet and as little as 3 feet in all directions. The receiver will pick up this radio signal and produce a warning tone and a static correction, which will cease once the dog returns to the mat.
The Stay! Mat may not be effective for cats and lightweight dogs because it may not be able to detect their weight when they return to the mat.
