HELP PLEASE! Ball python possibly starving?

[Anatopism]

A picture of the spider would definitely help us to determine the real condition of the animal. If he's a hatchling and still small, I would try a live hopper mouse. You can leave a hopper in the tank with him for a few hours, even overnight and leave him alone with it. If you can really feel the internal organs, it sounds like a pretty dire situation, so the sooner the better. If he's really that bad off, you may need to make a mouse pink slurry and feed him from a feeding syringe. Again, this is where a picture would come in handy so we can tell you the appropriate course of action based on the real condition of the snake.

I disagree with this because I have seen first hand what a Hopper mouse (yes, Hopper) can do to a healthy hatchling, let alone a weak or malnourished one. Fuzzies are safe to leave alone, even the stage just before their eyes open, but do not leave a Hopper mouse in a tub unattended, or any longer than you would an adult mouse.
