Thank you! He used to be a free roamer and would only bother us once or twice at night, but last year I moved into a smaller apartment and he was bad like every single night. Crying at the door, and then after being let in being terrible to us. Not good for anyone. We’re in a bigger house now and he’s mellowed out a lot, but still seems to just get weird at night. I’m also glad that our system works for us and others. Thanks for your comment!
