Is this a poop or regurg?

[Bogertophis]

Questions not asked.
1) What did the prey weigh?
2) Snakes weight?
3) Are you sure the prey was totally thawed?

...

Question was asked but perhaps not as directly as I might have, in my response (post #23): "... I don't think it's likely to be a rodent issue...UNLESS it was too big for him, & you haven't shared that information either- his size (weight & approx. length) compared to size (weight) of prey." and my inclusion of the feeding chart was for that reason especially.

But it does bear repeating! Sometimes it "takes a village..."
