she's really cute! i'm glad she's doing okay now. i have the same issue with my cat twitching her back and runs away but she does this only when she's mad.
it's funny because i remember around 6 months ago, my Pepz broke the spacebar on my keyboard. she also like to sit in front of my monitor so i can take a clear look at her instead of the computer. or she also steps on my laptop. and anything new that keeps my busy such as the speaker. i guess...
