Why do cats have 'leg whiskers'?

Cats possess whiskers, also technically known as vibrissae, that extend beyond their faces. These leg whiskers, scientifically referred to as carpal vibrissae, are attached to their forelegs. Robyn Grant, a sensory biologist from Manchester Metropolitan University, explains that facial whiskers are as sensitive as human fingertips.

Cat leg whiskers provide additional sensory input, assisting cats in navigating their environment, especially when light is limited or their vision is obstructed. These whiskers are attached to the carpal bones, which are located further up the leg compared to humans as cats walk on their toes rather than palms. The purpose of these leg whiskers in cats remains unclear, but they may aid in precise limb placement during complex movements such as climbing.
