What does it mean when....

[Bogertophis]

My daughter is 10. And now that you said that she does want to move a lot instead of sit still. I wonder if that could be it.

Naw, my snakes are all very comfortable with me & I'm quite mellow. Getting dumped on is rare for me, but it has happened a few times over the years...the most
recent was when I had my rosy boa out in wintertime & she slid into my shirt, which I thought was cute & funny until I felt something warm going down my back...

I think it's pretty random, they don't "mean" anything by it, but if we're "teachable", we learn to look for puffiness above their vent before we get too comfy handling.
