I don't see anything wrong with bribing her. At least initially. She will get to the point where she doesn't associate being caught with unpleasant things all the time and you won't need to bribe her anymore. But for right now, there really isn't much wrong with making her a little bit of a pet for a while. If her experience of people is that they are pretty well useless for anything pleasant, she's not going to be too inclined to change her mind about being caught.

If you're told about vampires, it's a good thing to be told about stakes at the same time.- Terry Pratchett
