GA_Ball_Pythons--does that mean that if they're in a dark room (such as one perhaps designed specifically to house reptiles, maybe a large warm closet) without regular light cycles natural or otherwise, they *won't* know? It was my understanding that they would even without natural light cues, but I could be wrong.

Interesting about storms and such--I'll have to look for that.

Also interesting, even if they wouldn't be able to tell in a dark room, that they can tell despite lights being on. My mice won't get really active until it's good and dark in their room, no matter how late I might be working in that room with the lights on. But that's not true for pythons, then. Very interesting.

Thanks. I wonder if any research has been done on this? Are they taking their cue from something other than light? What are they sensing? They are such fascinating creatures!
