I'd take it out of cedar chips. Then I'd probably take it to the vet to find out what the heck happened, the cedar chip thing might be a coincidence. They're bad, but I always thought they were a bit more slow acting.

"The serpent crams itself with animal life that is often warm and vibrant, to prolong an existence in which we detect no joy and no emotion. It reveals the depth to which evolution can sink when it takes the downward path and strips animals to the irreducible minimum able to perpetuate a predatory life in its naked horror."
