I am writing this because of a cat that my neighbor owns. I don't hate cats, I love them, I just have strong allergies that keep me from being near them. I was hoping for friendly advice on how to make my carport an uninteresting place to him. He recently started spraying. As I am house breaking a puppy, I am getting tired of cleaning up funny smells. We have never feed the cat or encourged it to hang out, because of my allergies. I have cleaned out the carport and sprayed it down with citris orange spay as I have read cats don't like the smell. This didn't work with him. I have read spicy works as well, but this is a carport, not a flower bed. The motion lights don't chase him off, and he is very people unfriendly. What else can I do to discourage the visits?
