It sounds to me like you have came a long way with Rosie! It is frustrating, but as everyone says on the forum, grey time moves soooo slowly... I don't think I would be able to get Timber to step up from inside his cage unless he was really anxious to go somewhere with me. As others said, that is his "safety" zone and he doesn't like to be messed with if he is inside. If he wants to interact, he comes out. It is troublesome knowing that in the event of an emergency I would probably have to towel him to get him out, but it is what it is. Hopefully that will change with time, but that remains to be seen. I have had him for six months. You are also very fortunate that Rosie doesn't bite when you are sticking your arm in there like in the first video. When Timber bites, it is a blood drawing, tear inspiring bite, not a warning nip. One of these days, I bet Rosie will take the plunge and bring that other foot along for the ride. It will most likely be from a cage door or perch though.
