New Question:
She loses control sometimes. She completely spazzes out on me with biting and growling. I can barely hold on to her. I tried scuffing her and telling her no, but it doesn't work. The tin can with pennies in it doesn't faze her.  I mean, we have major poltergeist problems when she gets so hyper. And I'm not doing ANYTHING to spur it on.  She just acts plain possessed.
