Just a quick update. The owner of the pet shop called this morning. The python I went to look at yesterday afternoon was found in his aqaurium this morning dead. It really pains me to see an animal neglected like this to the point where it can no longer survive. The one consolation I have is that my hunches were right. That snake was too far gone to be helped.
Anyways, I'm heading out today to check on another B/P that someone wants to re-home. I will keep everyone posted on what I find with that one this afternoon.
