I agree with Bo B and Bassetluv, and just wanted to add some things
. (Tidbits I've learned over time
.)
Here's what I think might help. Granted, this is more extreme behaviorthan new bunsnormally put out. Wonder if she has been mishandled in the recent past
onder:. This could contribute to this very scared behavior.
I say, just give it time. Have alot of patience
. (How long will you be keeping her for? Does your friend come over to try to get used to her and her to your friend as well? This will help. I'd hate for her to get used to you and only your scent then she is sent home with your friend, which is still a whole new ballgame to the bun, and you're back at square one.)
I wouldn't try to hold her or attempt picking her up. Let her get to know she's safe. Let her get to know her new surroundings, this could take weeks to months, honestly. When she is out, let her come up to you, if she doesn't-she doesn't. You can't force it, it will just happen when she feels secure doing so. (Treats will help of course, but not straight away.)
If they never get the sense they're safe, it won't happen. She'll just keep running from you or just sitting in the litterbox hoping to be left alone. That will get you nowhere. Then it will just take longer for the bun to trust you.
Also, if you can have it to where nobody is walking directly in front of the cage to go to another room, this will help her feel more secure. Just remember...baby steps.
Let us know how it goes. She'll come aroundin time
. Good Luck!
