I got my first boy when I moved out of my parents house after H.S. (mom hated snakes)...had him ever since he is now about 14 years old (I say about as I didn't keep records back then). He is super friendly and will crawl until my hand when I open his tub to "play" with him. He is a little over 5' and 3000 grams now. All my others are under 4 years old.
