A cat's paws serve as a one-stop shop for a multitude of uses. Unlike dogs, their paws can turn, which helps with climbing and grasping. They also use their paws for self-grooming, temperature regulation and heat detection. In addition, cats can feel vibrations on the ground with their paws, alerting them to potential prey. Once a cat is aware of prey nearby, the claws are activated, thanks to a special ability to retract and extend their sharp talons as needed. When a cat is self-cleaning or walking, however, the claws are retracted behind a sheath of skin.
