hey guys havent been here in a while but some may remember me. just got in a boa about 7-8 feet about a year ago. hes been fine with no aggressive behavior at all then suddenly he grabs at my leg and tightens around. my leg was purple and he held on for a good 20 minutes untill i finally pryed him off. i just fed him 2 xxl rats to ensure he is not hungry. this does not phase me as ive been bitten much much worse but my brother who is 11 used to play with him all the time. the question is should i allow him to handle it? is this a one time fluke ? or may he strike again and terrify my brother for the resto of his life? thanks.
