So several months ago my daughters opal corn snake (very small) escaped from its cage and was gone. We searched high and low for it, laid out food and heat for it, but have not seen it in a very long time. Over the last month or so it has started to get cold at night and the house has been in the high 60's.
Well today I opened the door to let the dog in and see what looks like a shoe lace lying across the threshold, half in the snow and half in the door. It was trying to come out of the cold into the house.
Now I have no idea where the heck this snake has been and I am relatively sure it hasnt eaten in the months that it was MIA. It had some black stuff that looked like dirt on its low jaw and was obviously dehydrated and had lost weight.

So I picked it up and put it into a sterlite container with a hide and a bowl of water. Ive been working to keep the container temp in the mid 80's. For the first hour or so it was fairly lethargic and didnt do much. After that though it was starting to look normal (albiet thinner) again and the black stuff (again I think it was dirt) was gone. So I fed it a f/t pinky (thats what it ate before it escaped) and it was gone within minutes. Its actually looking like it is doing fairly well.

Any suggestions?
We are going to take it to the vet tomorrow.
