Cats arch their back when they stand up as a reflex action that helps them stretch their muscles. This behavior, often accompanied by a big yawn and extended rear legs, is not only a way to wake their body up but also serves as a way to communicate. An arched back with fur standing on end can indicate fear or aggression, making them appear larger to a threat. However, in a relaxed context, it's simply a satisfying stretch.
