My reasons for asking are: what needs to be done to ensure an accurate necropsy? Skiploder shares some insight that the animal must be evaluated in a short window. Specifics I don't know. Thus asking my question to those that suggested it might've drawn the answer. No sense asking the questions if they haven't had a necropsy done to any of their critters.
And Seru's answer here is also why I asked, to find out what the cost should be as cost can be prohibitive to some people. I hope this helps you understand the relevancy of my question.
