I have a female leucistic Texas Rat Snake, approximately 9 years old. She has a lump that we have taken x-rays on, seems to be full of bones and broken up food. She acts completely normal - eats normally and has an appetite. She just shed a normal, healthy shed on 5/26. She has a few discolored scales near the lump, some reddish color and some a brownish color. We just changed her substrate, and I have more airflow coming into her tank. These do not look like mites to me. I am not sure what this could be, or what to do!
