have u tried feeding her small rats or weanlings? snakes are stretchy and it's amazing what they can swallow or fit into their bodies.

i have a few BP's that reached 200grams last month and are now taking rat weanlings. i was like now, they can't eat that. i tried it and bam! i got a few happy BP's with a nice lump in their bellies.

maybe your girl just needs bigger prey to start filling out her curves. but to be honest, i don't see anything wrong in that pix. she doesn't look long or skinny, just a normal healthy looking BP. maybe u need to take a pix of her stretched out fully or next to another one of your BP's.
