Bruce I cannot tell you how thrilled I am to read this. Considering the severity of this fire, it's about as close to a miracle as I can think of, to have all the snakes and rats survive it. Like Robin said I'd still watch them very closely for any issues from smoke exposure but just to go in there, expecting to remove their remains, and find them alive....you must have about fell over with shock!
This news has made my day my friend. I don't have a lot of contacts in the snake community in Canada but anything I can do, I will do.
