Query: THIS PRODUCT IS YOUR ANSWER!!

I have a cat that loved to urinate on my favorite lazy-boy chair. I tried many things, including the spray deterrents, and the Tattle-Tale sonic alarm (a piece of junk .. don't waste your money on that thing), before finally deciding to invest in a Scat-Mat, which admittedly is kind of costly. But I'm so glad I spent the money. This finally did the trick. It really does work wonderfully. Sure, you have to wonder how much it hurts the pet to step on it and get shocked, because I've accidentally sat on it a few times and got a heck of a shock, but pets can jump off the thing a lot quicker than a person can. It's definitely not going to hurt them. It's only powered by a 9-volt battery, after all. And like I say, this thing solved the problem. My cat has never gone near the chair again.
