Cats have whiskers on the backs of their front legs, as well.

Cats have whiskers on the backs of their front legs. These whiskers are called carpal whiskers, and they are located on the inside of the legs, just below the elbows. Carpal whiskers are about the same length as the cat's body, and they help the cat to judge the size and shape of objects in its environment. This is especially important for cats when they are hunting, as it allows them to determine the size and location of their prey without having to see it. Carpal whiskers can also help cats to avoid obstacles, such as furniture or other cats.

In addition to their role in hunting and navigation, carpal whiskers also play a role in communication. Cats will often twitch their carpal whiskers when they are feeling threatened or aggressive. This is a way for them to warn other cats to stay away.

Carpal whiskers are an important part of a cat's sensory system. They help cats to navigate their environment, hunt for food, and communicate with other cats. If a cat's carpal whiskers are trimmed or damaged, it can make it difficult for the cat to function normally.
