Results came back. It's an abscess. Not sure how she got it. I'm relieved it's not cancer or anything. She'll be put on antibiotics for 30 days. (She's going to hate it.) It's injections.
I'm going to pick them up probably Monday.
The anti-belly heat issue, not sure if it's because her belly was burned as a baby. (The thermoregulator was not powerful enough. I invested into an inkbird.)
Still working on cleaning her cage. I cleared out the substrate. I'm keeping her somewhere separate of the cage until I get it completely cleaned.
She mostly turns her head towards me when I make noise and is out of her cage.
