PetSafe ScatMat Indoor Electric Training Mat for Cats & Dogs, Sofa, 60″ x 12″

I have a big window in the living room that has a 4″ wide sill and my loveseat sits right in front of it. All of my dogs inevitably stand on the back of the couch and put their front paws on the sill to look out the window. This is a problem because a) they dirty up the sill (the couch is covered) and b) I have a set of sheers that are always closed and they step on them getting them dirty, tearing them or sometimes pulling them down off of the curtain rod. It’s very annoying and difficult to train them from doing.This product is really useful for that. Set up is easy with a 9v battery for power and then you just lay it on the area you want to protect. There are suction cups to hold the sheet in place. On the sheet are two exposed wires running its length. When something that can conduct power crosses those wires, it creates a circuit and a mild shock is delivered. You can set the level of shock and I put it to the minimum. I tested it on myself and it was a little more painful than a static discharge from a high pile carpet. The biggest issue for me was the distance between the wires. It’s wide enough that a small dog is unlikely to cover both with their paw and even a larger dog like mine (70 lbs) took a few days before she completed the circuit. When she did (the display shows how many times a shock has been delivered), the result was almost instantaneous – she no longer puts her feet on the sill. It’s pretty miraculous. Getting her to do anything is usually an exercise in futility but this product definitely did the trick. Too bad you can’t just rent them as it doesn’t seem like reinforcement is necessary, I guess it will just go into a drawer somewhere.Highly recommended with the caveat about the spacing of the wires.
