My shatter corn snake is like that with my son. Normally very flighty,and that’s once he’s wrestled out of the viv... Nate hits the room and I think the snake knows the vibrations of his steps, because if he’s awake, he comes front and center, pushing on the glass.
The snake comes right out to his hand, slithers around and hangs out for hours. This has been going on for 3 years.
