I recently pissed off my juvenile blood python (because I was a stoopid hooman) and got both puncture and slashing wounds as a result. I *think* she was the one doing most of the movement in trying to avoid me/go back to her hide, but can't swear to it.
Fortunately, Nageswari is still small enough that I didn't even bother with band-aids. And she doesn't seem to have held a grudge.
