Cats have a split upper lip called the "philtrum" which serves an important function in enhancing their sense of smell. This feature channels scent particles directly to the cat's olfactory system, which is critical for their survival instincts and behavior. In the wild, this helps cats detect prey and scent-mark territories, showcasing how nature has perfectly adapted their physiology for their needs.
