Oh and one other thing you can try which was suggested to me by a member here, Flint McCullough, is when you come in with food use a word like "Treaties" or whatever feels right for you - and kind of make a nice fuss about it. I would first knock on the door, announce myself to Cocoa, let her know treats were coming, and how good they were, and then, leave so she felt safe coming out to eat. Once she showed less anxiety around me, I began to stay in the room while she ate, but at the beginning I gave her total space.
