BP eats mouse in water dish?

ya i highly doubt that... they kill their prey by constriction.

i would think what the OP is observing as thrashing is the snake trying to get in to a position to begin swallowing the already dead prey.

You are probably more right. It's more likely trying to position it to eat. But even constrictors don't contrict the prey 100% of the time before they eat it. And by that I am not saying they will choose to nessesarily thrash to kill it. Sometimes jsut the bitting is good enough for them. I have had plently of times where thehy jsut take the prey and start swallowing. I have also had times where they couldn't contrict the prey when they probably wanted to (body wraped to much on a log as an example) so they move the prey around instead. Not really thrashing though. jsut trying to let their teeth do more damage would be my guess. Then they grab it by the head and swallow.
