Ok... this comment is COMPLETELY uncalled for at this point. She has had this snake for a week, and only offered over the last couple of days. Obviously IF he absolutely will not eat f/t something will be done, but very few things have been tried so far, and it is incredibly drastic and close minded to recommend rehoming just because live isn't an option at this point.
Many snakes won't eat PERIOD for the first couple of weeks in a new home, sometimes longer. Before rehoming, or even resorting to live, is recommended there are dozens of things to try first. She was obviously asking early on (before she had even offered a f/t) in order to stay out with the best chance of early success.
