A paw is a structure found in various animals that is typically located at the end of the leg and used for walking, running, and other forms of locomotion. It is composed of a combination of bones, muscles, tendons, ligaments, and soft tissue, and its specific shape and size vary depending on the species. Paws typically include pads or claws that help animals grip the ground, climb trees or burrow into the soil. They also contain sensory receptors that allow animals to feel the texture and temperature of the surfaces they walk on. Some animals have specialized paws that have evolved for specific functions such as digging, swimming, or grasping prey.

Whiskers, also known as vibrissae, are specialized hairs that grow on the face and other parts of the body of certain mammals, including cats, dogs, and seals. These sensory hairs are thicker than the other hairs on the body and are deeply embedded in hair follicles surrounded by blood vessels and nerves. Whiskers are used by animals to sense their environment by detecting even the slightest movement, air currents, and vibrations in the surrounding space. They help animals navigate in the dark, detect prey, and avoid predators. Whiskers are particularly important for nocturnal animals, who rely on their sense of touch to find their way around.
