I wouldnt be disheartened by one bite. Louie lunged out 2 times when i got him. I've never had a boa ever do that. I talked to the breeder and she said that was very unlike him as he was a really laid back baby. Well after a couple months of him being cautious of me, he has more or less come around. He doesnt try to lunge and he is starting to be much more inquisitive when out. Just got to give them time to settle in and get used to everything. Some snakes when overwhelmed with new stuff will lash out, some will hide, some will sit there and some will be more curious.
