When my snakes escape they are either behind the snake rack or on top of the rat rack, haha. She probably didn't wander that far. I've uh, misplaced snakes a total of three times (though I can totally argue that none of those were my fault ;]) and they never left the room. Close the door... if it's in a bedroom, look through dirty clothes, inside of shoes, etc. Dark, tight, and warm spaces. Look along the walls. Check your closet.
