What kind of substrate do you have? Is it at least 2x his height so he can burrow?

I don't have any albinos, so I don't know how it looks when they are about to shed. But I imagine that they are less glossy/smooth with duller color (the little they have).

Glad he has become more tame. Our KSB is very calm and has never bitten, but we got him at 5 weeks and handle him often. We've only had him for about 7 - 8 weeks though.

Sounds like you are on the right track! And I'm sure he thanks you for rescuing him!
