"This product is literally the only thing that's let us keep one of our inside cats an inside cat. A rescue, he's always been high-strung and territorial, and he eventually developed a spraying problem, I think triggered by stray Toms invading our yard (he could see and smell them through open windows). This was a last resort, but it works. There have been a few spraying incidents since, but in every case, it was because a plug in had not been replaced. It also makes both our cats more friendly and social (almost to excess sometimes, but a demanding cat beats the alternative in this case)."
