Amazing! 7'? How old is he? That is practically unheard of in the wild, isn't it?
I am currently rehabbing a 5' male wc black rat snake. He is SO docile and intelligent. I LOVE him, but plan on letting him go where I found him once he is healed.
We currently have 4 cb pet snakes (see sig); and I convinced that our next snake needs to be a colubrid, all b/c of the black rat. They don't get as fat as pythons or boas. Thus, 6' feet or so is not intimidating. I think the normal adult length is 5' to 6'. Correct me if I'm wrong, Mike.
