I love those boas, Harald. I love their "clean" lines. Nice birthday present, BTW. Are you singing, "Happy birthday to me, Happy birthday to me?"
As for mess, I've cleaned up many a mess working w/my boss' snakes. He has a lot of boas of all different kinds. Here's a pic of the aftermath of a Columbian giving birth. I didn't get to witness the actual birth but I didn't miss it by much.
I have been lucky enough to witness several births, though. Here's a Dumeril's giving birth.
She pops out the baby and after each one turns and looks at it. I wonder if she has any maternal instinct at all? I wonder if she is actually aware of and "knows" it's her baby?
(Forgive the crappy pics. That is cypress mulch and it is not red like in the picture. Some day I'm going to splurge & get a "real nice" digital camera. That day I didn't have my SLR at work. I'm still kicking myself for that one.)
