I have the most stubborn, persistent cat when it comes to him trying to get outdoors. Cat likes to lay in front of doorways and just wait for his chance To escape. I bought this mat, received it on Tuesday got it set up. Cat went on it once!, and will not go ANYWHERE near the door. I even try to pick up the cat and place him near the mat and he runs away from the door. He will just sit and give the mat dirty looks. This product has been a LIFESAVER. I have tried everything from sprays to noise makers and the cat found everything just amusing. So I keep he mat now at the door turned off for a reminder to him. Highly recommended for those stubborn guys!!!
