Depends on the snake and their mood at the time. If they are relaxed, they stay out longer. My ball usually only gets 30 minutes at most. More often it's 15-20. My Dumeril gets about 20 minutes at a time. And my BCI will sometimes hang out with me for as long as an hour. She loves to be out though. The others get nervous after a bit. Her...she could be out over an hour and will still fight me when I try to put her back.Silly girl. But she has her days too...and on those days she may only be out for cleaning and water changes. You just have to learn how to gauge their moods.
