You are correct my friend, but taking a snake to a vet, in most cases is an exercise in futility. My wife works for a vet and they call me to ask directions when someone brings in a snake. =) I am very skilled at parasiting a snake, but as you mentioned, chances are she is already gravid. If she stays with us, I will de-worm her in the fall. I have read panacur can cause ill affects on gravid females. For the mean time, going to move her to f/t frogs to start, should be on scented mice shortly.
