One of our cats had recently taken to using an entrance rug as a litter box. After reading several reviews, I bought it and placed that scatmat over the rug and waited. A couple of days later the cat approached the mat, stepped on it. The shock made her jump and she scurried away from it as fast as she could. She did come back to smell it once in a while but that's about as close as she gets. She no longer steps on the rug -- problem solved.
