Ash,
You poor thing. It is great that you realize that your kitty isn't doing it for any mean reason. She is just really confused and lonely. I dont think you guys have been moved that long yet, have you? So, what about crating her at night? In your room. She may just need some time to settle in. She may be 'calling' to the otehr cats...it is hard to tell. Tex does that cry at night sometimes, and it is kinda eerie, sad, and annoying all at the same time. Give her lots and lots of love right now. She needs it.{{{{{{HUGS}}}}}}}.
