Hmm, that advice sounds familiar?(my post #36) Double-check her temperatures too- make sure she's warm enough to digest. (is there a hide over the warm area so she feels safe to use it for long enough to digest?)
When was the last time she was fed? Seems it was an awfully long time for this to be undigested prey? Still, I'm glad it's not a tumor or true blockage of undigestible stuff.
