I prefer not to bother a snake when they're feeling safe & secure in their hides. For the same reason I'd react badly for someone coming to my door selling something at 2 am when I'm asleep.When you lift up their hide, a snake is instantly feeling exposed, afraid & potentially defensive. I much prefer to approach & pick up a snake that's already awake, at least- & preferably moving around in their enclosures (-most of my snakes are more active than BPs though).
And of course, I don't handle a snake for at least a day after they've eaten- preferably 2+ days after (depending on the size of their meal).
