A few months back I encountered a similar situation at Petco, but this snake was much worse. When I first walked by the enclosure, I thought it was dead. But then I saw it writhe and twist, trying to correct the position of its head and I nearly blew a gasket. After an angry talk between the employee who took it out for me to hold, the manager was called. He was fully aware of the condition, saying that it just wouldn't eat. But why the *** was it still on the sales floor, being squashed by four other pythons?! I pretty much knew it would die at this point, but he agreed to adopt it anyway-- then he sprung a 25$ nonrefundable pricetag at the register when she was already boxed! I could hardly say no at that point, so I spat up the money and left.. She died later that night, but at least she was warm and as comfortable as I could make her.

I refuse to let this pied die like that if there's anything I can do to get it out of there.
