[cypher]

He may be put off by any scent on your hands, I would wash your hands with unscented soap before interacting with him, you could try rubbing your hands in the substrate too.
Some can be a bit more independent than others but I would just persevere, if he doesn't seem too nervous then begin getting him out, he may interact better out of the cage, give him plenty of things to explore in the playpen or other safe area & just slowly begin interacting with him.
If he's monkey barring then make sure there's nothing hard that he can fall on just in case.
