Have any of you ever subjected a ball python to long periods of exposure to a mirror? My new snake came in with a tank with a mirrored back wall, which is kind of cool because I can see where it's head is easily, but I have seen it appearing to be keeping an eye on "the other snake" and rubbing against the back wall but have not observed any rubbing on the front. I've never kept a snake with a mirror yet, and I wondered if anyone had and observed behavioral or other correlations or results of the practice.
