Thanks for all the great suggestions and advice.
I am going to try getting a wand toy for her, and seeing if she warms up to that. I do wonder if she was perhaps mistreated, as fearful as she is...but of course she may have been a stray too, I don't know. One good thing is that she and Arnold love each other; they sleep cuddled up together, etc. (yes, I did wonder if that's perhaps why she's not in a hurry to get attention from me), but this is actually part of why I got her, as I felt sorry for him being home alone when I work long hours. So mission accomplished there! Hopefully the other part--her liking and trusting me--will come around sooner rather than later, but it is good to know that probably in the future it will--on her schedule, lol! Thanks again!
