Not all sellers tell the truth, or the whole truth...not if they think the sale depends on their answer. To me she looks either like she's been under-fed for a while, or
like she has laid eggs & not regained her body weight back. Another possibility is something "stealing" her food: meaning intestinal parasites. I would get her stool
checked ASAP. Pretty snake, hope you get to the bottom of this.
