Why do cats have whiskers? - 4aPet

Whiskers are a highly sensitive organ, which helps inform cats about surrounding objects, air movements and more. Their length helps a cat to gauge its ability to navigate a tight space and they can be raised or lowered as a means of communication or during stressful events. Because of their vital importance, never trim or pluck your cat’s whiskers.
