I've caught my single ball python doing some of the craziest things that even sometimes cause me to rush over in panic only to find she is just not using her brain...assuming she has one.
I have caught her twice in my year of having her arch her head and neck back upside down and running her head and neck along the top of the cage only to flip back around when she can't reach any farther. It's not corkscrewing or just reaching pencil straight into the sky but it is very weird. Is this some form of stargazing or just her being weird and crazy?

unfortunatly I don't have a video and I don't know how to attach a sketch but hopefully you get the right idea...I'll continue to figure out how to attach a sketch.
Thanks for all your advice!
