Final answer:
Carpal whiskers in cats can be found on the back of their front legs at the metacarpophalangeal (knuckle) joints. These whiskers aid in navigation and environmental sensing.
Step-by-step explanation:
A kitty's carpal whiskers, also known as carpal vibrissae, are located on the backside of a cat's front legs, specifically on the metacarpophalangeal (knuckle) joints. These sensory hairs help the cat sense its environment, particularly when navigating through narrow spaces or during hunting. They are different from a cat's regular whiskers, which are found on the face, and play a crucial role in helping cats judge distances and detect changes in their surroundings.
