Simply Works and is Not Harsh
I tried it first before I used it to keep my cat from using my couch as a restroom. It is like a shock you get when you touch a door knob so not too strong (on the lowest setting). I put it on the couch and even if I forget to turn it on she has not done her business on the couch since day one! now if I could get one for my bed that would make it all better!
