Dumerils are the ball pythons of the Boa World. They are picky eaters as babies and they go off feed. 99% of dumerils in captivity that I've seen look overweight. If she's healthy, active, and not showing any signs of losing weight...don't worry about it. She'll eat when she's ready. I'd just stop trying to feed her for a few weeks. As long as her backbone or ribs aren't starting to show, she'll be ok.
