So I posted a forum recently, asking some questions about my supposed male ball python, and about his growth/gender. Since then, even though I got decisive responses, the questions were still nagging me. I finally looked up several "popping" videos, in order to sex Zhang myself. After I finally got up the courage to do so, I followed the videos to a T!! It was easier than I thought, and Zhang is not a male, but actually a female...
I double checked, and I double checked a few days later. I'm not doing it wrong, when I pop her, it looks exactly like the female popping videos I've seen, and not even close to the males... Welp... I guess I actually have a female.
