Very true. I had a typo in my original post; she is on a full-spectrum anti-bacterial. Her fecals and acid fasts were clean, so no parasites. Crypto can be detected in fecals (from what I've read, 4 negative fecals indicate a crypto free snake). They couldn't draw blood to confirm anything. She has not regurged in our care, nor is she displaying any crypto symptoms (belly swell, chronic regurge, etc.) This seems to be purely neurological..maybe age related manifestation?
