My first one was from a manager of a pet store that got him from someone that wasn't feeding him enough. Still the only snake in the house that will refuse to eat a black rodent. The second was one that someone dropped off at the other pet store, supposedly came from a home of a deaf person and they thought loud noises would bother her. As of now both are fat and happy, I'm pretty sure my first is a male and second is female between size difference and the way the first guy acted a few hours after we got the second one home. Never seen him so active the whole time I had him, even now he'd rather be a lazy bum.
