He's looking much better!

Honestly he doesn't look skinny so he must have either recently escaped or found some mice or rats when he was out.

Keep up the good work! Don't be too afraid of getting bitten. Have had my BP for almost 2 years now and i've never been bitten.

Grab a pair of leather gloves, if you have them, or use the arboard trick Vypyrz mentioned. All in all, great job! You've done more than most people would and that is commendable!
