My wife bought a pretty shy kitten, but after a while it got used to me and was even jumping on my shoulders in the morning purring when I was getting ready for work. She almost wouldn't leave my side.
A week ago I was messing with the cat and she must've been in a bad mood, because she bit my finger while I was holding her (she's never minded me holding her previously). Instinctively, I went to shake off whatever was biting me; this caused her to be thrown straight down. She just froze on the floor instantly. I went and picked her up, cuddling her and trying to make her comfortable (she's uninjured, by the way), but now every time she sees me she sprints away and goes to hide.
She barely takes treats from me and when she does goes back to sprinting away. The odd time I manage to stroke her, she starts purring but at the same time trembles with fear. I need to know how I can improve my relationship with her or get her to be more comfortable with me again.
