It depends very much how you view your snakes, those breeding them or have large collections i don't imagine would handle regularly all of their snakes... I also believe it does the snake no real good at all apart from a bit of a change of scenery. I was one of the bad ones and handled my snake as soon as i got her home and did for the next few weeks almost daily.... i don't know if this is just her temperament or me doing that but she now sits and watches movies in my hair, never taken a snap and loves it outside her enclosure, she's a coastal btw.
