A cat's just not a cat without their distinctive feature: the whiskers. But why do cats have whiskers, anyway? Can you trim cat whiskers?
Believe it or not: Whiskers play an important role in your cat's ability to sense the world around them. Here's what you need to know about your feline friend's unique feature.
What Are Cat Whiskers?
Although they look like antennae and have a radar-like function, cat whiskers are highly sensitive hairs made of keratin, a protein also found in their claw sheaths. The whisker hairs, also called vibrissae or tactile hair, are embedded deeper in the cat's skin than their fur, and each follicle (where the whisker connects to your cat's body) has many sensitive nerve endings.
A cat's facial whiskers are the most prominent of all animal whiskers and they're very much a part of a cat's distinct look. Cats typically have 24 whiskers on their muzzle, evenly distributed with twelve on each side. Generally speaking, the length of their whiskers is proportionate to the width of their body, notes Animal Planet. However, if your cat puts on a few extra pounds, their whiskers do not grow longer to match up. Cat whiskers also grow on their chins, above their eyes and on the backs of their front legs. According to the Guinness World Records, the longest cat whiskers on record belong to Missi, a Maine Coon whose whiskers measure 7.5 inches!
Why Do Cats Have Whiskers?
Whiskers aren't just hair. They're honed tools connected to one of your cat's five senses: touch. Whiskers help a cat with spatial determination ("Can I fit through that narrow doorway?"), expressing their feelings and locating their prey. All cat whiskers work together as "touch organs" for your kitty, helping them maneuver around furniture or trap that catnip toy they've been stalking.

Whiskers allow your cat to "see" in the dark because the whiskers pick up on the airflow around them, allowing them to detect their intended object down to its exact location and dimensions. That's a pretty impressive superpower.
As a form of cat communication, whiskers can convey that your furry friend is not happy. As Cornell University's College of Veterinary Medicine describes, cat whiskers that are "flattened or pressed downward onto the face" are a sign of aggression.
