I've sold several hatchlings in the past as non-feeders, making people are really good deal on them (I sold 8 for eighty bucks, shipped, last time I did this, I think!), and in each and every case, those crazy little snakes have eaten for their new owners within 48hrs!!!
I don't know what it is about that plane ride that makes them willing to eat, but one of these days I'm going to talk my Dad into just flying my poor eaters around in his plane to see if I can get them to eat that way! Who knows?!?!?
It'll be my luck that it's the actual sale of the animals that doest it for them . . .and not the plane ride after all! Oh well.
