I'm just curious...why wouldn't it have a very nice life?
Seems to me that as long as it is healthy and vivrant, and you can keep the two heads from trying to kill each other durnig feeding, an anomaly such as this could live a long and happy life as a pet.
Granted...in the wild, this thing would probably not live more than a day or two, what with 2 heads trying to flee from predators in opposite directions and such. But as a pet, it seems to me that this snake(s?) could live a full and happy life, and make the owner incredibly proud.
I would take it, for the right price, as long as I knew it would eat properly, and live healthy if kept correctly...
