Well the funny part is both of my male boas are like that. Rango will watch you like a hawk and follow you around if you walk past him. It's only the males. The females dont even react to me walking by. And if you take the males out of the cage, they are fine and crawl all over and check everything out. It's only when in their cage and seems to be when they are hungry which is pretty much any day from the 2nd day of feeding to the day of the next feeding lol.
