I've heard from a great many people that Rosy Boas are some of the most chill, non-bitey snakes out there & from a few people that they are the meanest nastiest biters out there. (shrug) I guess that just means a fair number of them are great snakes but if you get a mean one, it's really mean. My male is the most chill snake I have & the one least head shy. The female is pretty close in temperament to my tamest corn, pretty head shy & wants to be going & exploring the whole time they are being held. Neither of them has ever looked the least bit like they were going to strike, but I've only owned the male somewhere around two months & the female for one month.
