So I recently inherited (er...stole?) a Kenyan Sand Boa from my brother's crazy girlfriend. He (the snake not my brother) was being neglected pretty badly, so I stepped in. Though she showed interest when she first got him, she quickly lost it. She stopped handling him, kept him in a smaller tank even as he grew, and eventually my brother was the one who fed the snake. She just ignored it. Needless to say, poor Louie has become a very anxious and frightened snake. I have since moved him into a larger tank with more sand and he has become somewhat happier. My biggest problem is that he cannot handle being held or picked up anymore when he used to love it. I've had and worked with snakes before so I know how to handle and care for them. However this will be my first time trying to retrain a snake. I've already bought a new pair of lightweight gardening gloves that are currently residing inside the tank with Louie and after he gets used to their presence I'm going to use them to handle him until he learns that I'm not going to hurt him. My question is this, when he bites me, which he inevitably will, do I let him hold on until he feels safe, or pry his mouth off immediately? While I don't want him thinking it's okay to bite me, I also don't want to make him any more stressed out. The poor thing has dealt with enough.
