First off I'll start with husbandry. Humidity is at 80%, hot side 88°, cold side 78°, hot spot 93°. Feeding on larger small rats weekly with no issue. Now the question is, should I be worried? My female ball python ate Saturday afternoon, I weighed her (740g) and I put her back. Today I got her out since she was acting like she wanted out and I weighed her again just for the fun of it (757g). She gained 17g overnight without feeding inbetween... Is that cause for concern? How could she gain so much without even eating? Could she possibly be gravid? (The previous owner had her with a male but was under the impression that they would get a brother-sister relationship from being housed together and that they would never breed.) Any help would be greatly appreciated. Thank you.
