Did you know?

Cat and dog owners who witness daily their pets' methodical body stretching upon awakening might wonder if there is a word to describe their routine—and there is: pandiculation. Pandiculation (which applies to humans too) is the medical term for the stretching and stiffening of the trunk and extremities, often accompanied by yawning, to arouse the body when fatigued or drowsy.
