When i brought Dorian home at 3 1/2 years of age, he was totally cage bound and hand phobic. It took over a year of me sitting beside of or on the floor in front of his cage. It took over two years before he so much as poked his head outside of the cage. Let Vim get comfortable with the members of your family, and let her observe things from a safe spot. I don't see any problem with letting her climb out of her cage. Lots of greys are cage defensive. Welcome to the forums.
