By what we identify as yawning, they are stretching and realigning their jaws in order to either prepare to eat, or to readjust themselves after eating. Your snake may yawn once or even multiple times to reposition their jaw comfortably, which is completely normal.

A very small snake can easily disappear behind baseboards, into the space where walls meet floors, cracks between floorboards, heating and AC vents, inside furniture (under and behind drawers, in box springs, inside appliances) and anyplace where a mouse has chewed an opening into a wall.

If you find a dry, scaly sheet of the skin or a crumpled heap somewhere close to an entrance into the walls of your home or small space areas. If you are inspecting a dusty area or crawl space, you might notice slither tracks that indicate where a snake has traveled. Snakes have a distinctive smell that is noticeable.
