All, thank you for your replies. They really help! (Six months without eating? HOLY CRAP!) I'm a wee bit less worried about my boy now. Also, his belly is pink now so he's getting ready to shed. We'll wait until he sheds before we offer again.

I apologize for taking so long to get back here. I had a family emergency to deal with.

Thanks again, y'all. (6 months?? YIKES!)
