I was wondering about the same thing. My butter and my champagne don't smell at all. I bought a normal the other weekend who smelled strongly, and after her shed there's still some odor, but not as much. How long have you had your snake? I don't know much about snakes, but suspect that some of them might have gotten something on themselves, maybe from a dirty enclosure or something, that might take multiple sheds to go away. My non-smelling snakes came from breeders, and the one with an odor came from a big box pet store.
