Maybe ask for him to cover a necropsy? What a nightmare. Considering the condition and age of the ferret he has no reason to blame you guys for it, but for some reason (and the insistence on the vet visit) I have a hankering he's going to go that direction. Keep us updated and good luck, I'm sorry it ended so abruptly. At the same time, I'm glad the poor thing is out of it's misery, they seem like lively little critters
