ditto on the eye check. i also have a VERY mellow VERY friendly snake, so if he gets hissy pissy (which is usually right before feeding day!) i just let him be. i also leave him alone if he's planning on doing the shed dance, cuz ya kno, i compare it to like, having a sunburn and peeling the narsty skin off yer back... ITCHY AND UNCOMFORTABLE! lol...
and i don't know what the deal is, but he is definitely more chill and relaxed during the day (haha thats probably because he'd rather be sleeping)
i handle my snake during the day and let him do his thing at night!
