Query: Did not work!!

My cat Maddox used to run outside all the time, so I bought this product to deter him from running. It did not work! He still ran outside. I also tried to used it outside my door because we had a pesky stray, and it still didn't deter the stray either. It does not work! If a cat wants to go somewhere, they will!
