Seems to work but smells BAD.
Used this for 3 days now. The offending cat has not been back to spray on my front door. It's important to note that there is a fairly large gap at the bottom of my front door so scent gets into my house from my front door really easily, so the smell of cat spray was driving me insane. I had tried several things but nothing had worked so far. I'm happy with the fact that this seems to be working so far. The one downside is it smells AWFUL. better than cat spray but just barely.
