Well, that's a tuffy. I would be careful of tieing him up tight, because that mite get him tense, like he is all caged up all the time. And its great with the stroking and bonding, he mite still be ajusting, also, don't get upset or tense about it, because they can feel when your tense, nervos, or upset, and that makes them the same way. (you mite think that's crazy, but its true). And maybe your getting so upset, that you mite be letting some anger out on him, and like I said he can feel it. Im not saying that's what your doing, just make sure you don't, cause it can affect them. But its great taht your trying, just keep trying!
