I put a few new vines in my veiled chams cage today and he won't go on them. I I put a vine across the corner in the top of the cage to give him a good spot to bask. Ever since I put it in there he won't grab it and is avoiding having to use it to climb. He seems almost afraid of the vine branch. Should I get rid of it or will he just take a little while to build confidence in using it.
