I agree, feliway is a Good Thing if you haven't tried it yet. Available as room diffuser or spray, helps reduce anxiety level of kitties to help with situations like meeting new cats, being in new spaces. Also reduces marking behavior like scratching, spraying because it basically tells cats they have already marked a space, so they don't need to again. Room diffuser probably makes the most sense for this situation. Looking forward to seeing you and your new kitty soon now that I'm in the neighborhood!
