Kuno,
This might lead to absolutely nothing, but
IF there's a way... I know who could either help you or who could tell you who to contact for the right information. We have a member called "cascabel," who is doing graduate research with wild
T.s. tetrataenia in Northern California. I don't know if she maintains any in the laboratory, but if anyone can help you... she can. There's is a slim chance for success, but the rewards would be tremendous! Here's a link to her profile (
http://www.thamnophis.com/forum/members/cascabel.html). Try sending her an e-mail, and be sure to include a picture of your babies

. Best wishes,
Rick
P.S. Just to be clear, she couldn't send you any, but she might be able to put you in contact with the proper authorities.
