Aw Devon, I wish I knew what to suggest. Kaedyn did the same thing with my birds when I first got them. He would dash from the living room straight to my room and lunge at the cage. Thank god he has stopped doing that! I did some boundary exercises with him but I can't imagine using the same method for a cat. Perhaps the only solution is to not let Amber in your room at all? Sucks that she wouldn't be able to go into your room since she likes being in there, but I think not having access to one part of the house is a heck of a lot better than being rehomed.
