Is there any way to tell if a ball python is gravid. I just bought a new ball python, from a pet store, she is about 1750 grams and only 3feet 8 inches long. I have never held a gravid bp but I think this one feels very lumpy. The pet store said she has had her only 6 weeks, and only has been feed once a week. I know I should not buy inports but there was something about this snake.
