Quit rat-packing Rob. He isn't saying anything that is unreasonable. If Mike is worried about something more sinister, a necropsy is in order.
He can post the results here. If the animal had an underlying condition, then LLL can compensate Mike for the necropsy. If they balk, then they will be outed here in public. I'm sure LLL would realize that the cost ramifications on future business far eclipse picking up the necropsy tab.
If the animal has something that can threaten Mike's collection, then LLL reptile can compensate Mike for the necropsy and they can open a discussion on what other compensation may be in order to ensure the rest of his animals remain healthy.
