9 Interesting Facts about Cat Whiskers That Will Amaze You

I know, I know. You think you know all about cats.

But did you know those cat whiskers are actually called vibrissae? Or that they grow in three different lengths? Cats use their whiskers to detect objects around them and help them navigate the world.

Here are 9 interesting facts about cat whiskers that will amaze you!

My name is Derrick, and I write for Simply Cat Care. Our goal with this website is to help cat owners learn more about taking care of their cats.

I am not a veterinarian and I recommend seeking the advice of a vet for any further questions relating to your cat’s health.

Let’s get into it!


1. Whiskers Help Your Cat Catch Prey

Did you know that cats need whiskers to help them hunt?

It turns out cats have a lot of difficulties seeing objects in front of their face. To overcome this, your cat will push its whiskers out to analyze distance.

The whiskers themselves contain sensitive nerve endings that help with sense movement.

Sensory information provides your cat vision of what’s in front of them. This is essential information needed to track prey and land a fatal bite.

Did you know that the scientific name for whiskers is ‘vibrissae’, which translates to vibrate?

This vibrating feature, called whisking, is one of the main functions of the whisker. The whiskers gather sensory information about the environment during a search.

The whiskers act as tactile hairs, which means they are sensitive to touch.

2. Cats have 24 moveable whiskers on their face

Whiskers are important to help your cat balance and stay on its feet.

What’s more, whiskers are twice as thick as regular hair [6]. Embedded deep in the cat’s skin, the whiskers are very sturdy.

There are 12 whiskers on either side of a cat’s body around the face (either side of the nose), near the ears and chin.

Each side of your cat’s face has an even amount of whiskers which is important for balance. 

Your cat has some whiskers on the base of its front legs and forelegs (called carpal whiskers) to detect vibration in the ground.

3. They show if your cat is confident or afraid

Whiskers show your cat’s changes in mood.

Your cat can display its mood changes in several ways. Since the whiskers connect to the brain, they will show stress or relaxation in your cat.

When your cat pulls its whiskers back, this position may show fear. Whiskers pointed outwards show comfort or confidence.

Think about that next time your cat struts around the house with a swagger.

4. They can help kitty squeeze through narrow gaps

Cats love squishing into whatever objects they can find. Cats use their whiskers to help navigate tight gaps.

They provide information on how wide or narrow a gap is, to see whether the hole is ok to fit through.

This will help your pet decide whether it’s ok to move forward.

Let’s be real though, they are going to try to slink into that gap anyway.

5. Why your cat’s whiskers are usually white

Everyone knows cats can come in with all kinds of colors and patterns. Despite this, a cat’s whiskers are usually white.

This is because melanin supplies the pigmentation of the fur.

Whiskers form from rings of dead skin cells that rise and protrude from the skin.

During this process, the layer of cells on the outside falls away and leaves the unpigmented shaft to turn into a whisker.

6. Cats have whiskers to detect sounds from the ground or air

Cat’s whiskers can detect vibrations in the air and ground. 

Sound frequencies cause the whiskers to vibrate at a rate of ~0.1s. The whiskers on the legs help cats with ground detection.

This aids your cat in its hunting adventures, as it stalks a few flying insects around your backyard.

7. They can detect how hard a surface or object is

When your cat grinds up against a rough surface it tells your cat what is in store. 

The nerves of the whisker give your cat an idea of what kind of object it is coming into contact with, and sends the information to the sensory areas of the brain.

A cat might have more confidence pushing into some bushes for example, as opposed to some hard stones.

8. They are sensitive to eating and drinking

A big bowl of food seems like a great idea when feeding your pet, but your cat might not be so impressed. This can be unpleasant to lick.

Your cat’s whiskers rub the bowl too creating a so-called ‘whisker fatigue’.

A better option is a flat saucer, or even a paper plate, which gives your cool cat an easier time accessing their food and drink bowls.

The bowl can be irritating especially if coming into contact with water. A cat finds getting its whiskers wet an unpleasant experience.

9. Do not trim the whiskers

It might seem like a good idea to trim extra long whiskers, but this is not helpful to your pet. 

Your pet needs its whiskers to help sense things in the environment.

Even trimming one whisker can be a harmful experience for your companion. It’s better to let your pet shed its whiskers, or get professionally groomed by a vet.
