I have had a female die suddenly , but was nothing like what you are explaining. The only thing you can do really is go to get a necropsy. Freezing is bad if you want one done so always refrigerate. And I beleive you have to get the deceased to the vet asap so he has it as fresh as possible. I had to Fedex overnight that female I lost to my vet specifically bc there was no way i could drive out there the day I lost her. He had said I needed to get her there by 24 hours. I'm sorry for your loss that's horrible. Idk what would affect a snake within 24 hours. The only thing you can do is qt that girl and watch everyone. I'm sorry.

In that case I think we'll just throw it out. The smell was awful so we've had him in the freezer and it's been quite a while. Ugh... I doubt there's much more we could do to prevent the female from getting sick, anyway.
