How could somebody leave a snake on a door step overnight and at those temperatures to boot? Geesh! Well, at least the poor thing is in better hands now.

I don't have a clue what it is but I wanted to wish you the best for this little fella. I'll be checking back for an updated post. Hopefully you can talk your vet into making time before Tuesday. If not, is it possible that maybe you could find another vet, even if you have to drive further?

Good Luck!
