You should be blocking access to places she shouldn’t be rather than chasing her away. That would be terrifying for her. It’s good you’ve stopped doing that but she’s probably still somewhat fearful because of it. How long have you had her and how long since you last chased her?

I think patience will be key with this one. As difficult as it is, I’d say stop approaching her outside of hand-feeding her. If you’re not giving her food and you’re not trying to get her away from someplace dangerous, just lounge around the area, not necessarily trying to approach her at all. If she comes near you, that’s fine, but don’t try and pet her unless she asks for it.

My Fernando occasionally likes to try to give me the slip and get out into the apartment – he did that last evening when I was cleaning out the buns’ litterbox. I’m pretty sure that he does that in at least some part as a game with me. I have to be careful when getting him back into his cage to not appear as though I’m chasing him, and to handle him as gently as possible. Happily, he doesn’t appear to hold grudges about that since he’s back looking for attention or treats within a few minutes! My own main issue with building my bond with Panda and Fernando is trying to not be too importunate about wanting to pet them , especially Panda (Fernando is cool with it). The thing we all have to remember is to let them set the pace for establishing the relationship and just be patient.
