Just looking at the pictures, the bottom half of the snake looks a little full - there is more spacing between the scales than I would expect to see. Do you have pics that are zoomed out some?

When you feed, do the food items make a noticeable bulge? What do you feed, and what size? Also, has she been passing stool/urates? I'm wondering if it was either a food item that was too large, and maybe started rotting before she could finish digesting it, or if she's backed up so much that the food couldn't get through?
