Ok. I made a mistake on my original post.
I meant that I picked up the ferret on Friday night. Not Sunday.

Here's an update:
The owner finally called back. He wanted us to take her to the vet today and get blood tests run. I have no idea what a blood test would do for her. It would do nothing since her main issue was the untreated insulinoma plus old age.
But we agreed to take her to the vet today. And start treating her adrenal as well.

Well...Today, she woke up. She started eating fine, then suddenly freaked out for a few seconds and dropped dead... I tried giving her CPR but with no success.

I texted the owners girlfriend the whole situation.
The guy doesn't have a reliable phone. I think he's using an internet phone number?? But he called after a few minutes after that text. He refused to hear it. He just kept telling me to take her to a vet to double check she was dead. I said "ok." then proceeded to ask him what I should do with the ferret once she was confirmed dead. He just said take her to the vet, take her to the vet. Then the phone call dropped.
As someone who deals with dead animals pretty often, I'd like to think I know what a dead animal looks like. This ferret IS dead....She's loosing heat. Rigor hasn't set in yet. But I am 110% sure she has passed.



This whole situation was a nightmare.
I had no idea that this would go down so bad. The president and myself assumed the ferret was a healthy ferret that just needed a temporary home.
