Brody is so cute, Lisa, and what a joy he will be when you finally get him home.
He should be bonded to you because you hand feed him but he could possibly pick someone else as his favorite as I am sure you have already heard they can do.
Yes that cage sounds plenty big enough and especially if he is out of it for lengths of time, is about the size of mine.
Thanks for sharing some pictures of Brody, he is a fine looking Cag.
