Thanks, everyone! I'm feeling a little better now.

I will try to get a video this Saturday (her next feeding time). She only does it when she eats; no "wobbling" or shaking at any other time. I never thought much about it until today, when she looked like she had a palsy or something. I don't usually feed during the day but she was actively hunting so maybe being pretty hungry was a factor? Hmmm...

I'll try to post video on Sat. Thanks so much for the ideas and support!
