Hi guys, first time poster here. I've had my Murray Darling Carpet Python, Matilda, for 19 years. Something I've noticed that started happening (twice now, once in August last year and again this week) is that when she's hanging out and crawling around my arms, she will just be laying there then decide to casually sink her fangs into my arm. It's not snapping or striking, and doesn't seem aggressive, just wondering why she would be doing this. Some things of note, both times she's in a stage of not eating (because of the cold) so it could have something to do with that? She hasn't bitten me in over 15 years, so I just think this is strange. Is she getting old? Or just reacting oddly during her brumation period? Thanks for any responses.
