Cat Whiskers & Dog Whiskers: What Are They For?

by | Jun 11, 2024 | Cat Behavior & Care, Dog Training & Care | 8 comments

Cat whiskers serve important functions.

I’m fascinated by kitty whiskers, how about you? Does your cat have lots of whiskers, or only a few? What about your dog? Have you noticed how s/he actually uses them? Seren had a “wild” whisker that started to grow curled forward once she became an aging kitteh. And for some of the longer furred cats and dogs (or those with curly fur), you might not even see all of the whiskers.

Whiskers also express emotion!

Whiskers are a type of specialized hair referred to as vibrissae or sinus hairs. They’re most prominent on the pet’s muzzle. But take a moment and look–many cats also have whiskers on their eyebrows, toward the rear of their cheeks or below the chin. Karma-Kat even has some on the underside of the lower forelegs. Whiskers are very long and stiff, yet flexible, and serve a sensory function for the cat and also the dog. Think of whiskers as a kind of antennae.

All About Cat Whiskers and Dog Whiskers

The hairs are seated deep in the skin, with the base of the hair surrounded by a forest of nerve endings. These nerves register the slightest vibration or contact with the hair. Whiskers detect everything from the measure of a narrow opening, to shifts in the wind and barometric pressure.

Whiskers also protect the eyes from injury, providing a startle reflex that shuts the eyes if anything touches them. Cats and dogs also communicate with their whiskers–learn to decipher felinese in the ComPETability book. Equal time for dog whisker talk, learn more in the ComPETability (dog) book here.

Cat whiskers are also said to be good luck. For a while, I collected the whiskers that Seren shed, when I could find them. What about your cats? Are the whiskers the same color as kitty’s coat, or a contrasting color?  Curly or straight? Some cats groom off each other’s whiskers, too. (I wonder what they taste like…)

    This was such a great blog subject. Thomas, my male yellow tabby has real long white whiskers. Macy, my other yellow tabby and Thomas’ sister has long white whiskers also but a couple of black ones mixed in with the white. Never had a cat with multi-colored whiskers. What causes that? Might be one of those things like Thomas and Macy having freckles on their lips and roof of their mouths. I do find whiskers laying around and it’s amazing how long they are and how stiff they are on the end that goes in the skin. Cutting cats whiskers off seems so cruel and reminds me of a parakeet I had when I was 16 and my 8 year old cousin spent the night with us. His mother picked him up early the next morning. After he left I went and took my towel off the cage to feed my bird and my cousin had pulled out a couple of it’s feathers and blood was in the bottom of the cage and there laid my sweet Henrietta. I guess doing that was so traumatic that it just killed her. I was sooooooo upset. Animals have feelings too.

      Hi Patricia, since the whiskers are specialized hairs, I suppose the color arises from the same place the coat color comes from. Some cats have contrasting whiskers, and others don’t. You’d think if the visual communication is important, then all cat whiskers would be hi-def color contrast, though. 🙂

      That’s terrible about Henrietta! I hope it wasn’t intentional…maybe he wanted to get her out of the cage and grabbed feathers, and yes–they bleed. Shock easily kills those little birds. So sad…

    Mom told me about when she was a kid their family had friends and their little boy was very nasty. One day he cut off all their cat’s whiskers. The poor cat was lost…it was like having the gps go off in the middle of a huge city. Whiskers are important, not just for decoration. Eventually kitty grew a new set but I guess it was not pretty!

      Emma that’s p-awful, the poor kitty. But you know, some kitties “barber” off each others whiskers, too. Wonder if that’s like biting your nails and just a nervous habit?

    If it’s possible to have whiskers there, Simba has them. I have seen whiskers on that cat where I’ve never seen whiskers on a cat before. Nose, eyebrows, chin, cheeks, feet… she’s got whiskers EVERYWHERE. Which now I think is a VERY good thing given she’s going blind, so I’m sincerely hoping that will help her navigate if/when she loses her vision completely.

    The neatest thing I’ve ever seen done with whiskers was this: http://browse.deviantart.com/art/Lio-s-life-size-urn-cat-memorial-331735173 Through the life of their cat they had collected whiskers that were dropped, so once the cat dies they got used in that sculpture.

      Holy cats! That sculpture is amazing.

      Yes, I’m sure Simba’s whiskers help her get around even she’s having trouble seeing.

Dog Problems? Cat Concerns? Here’s How to Find Pet Behavior Help

Do you know how do you find pet behavior help? As a certified animal behavior consultant for cats and dogs, I receive many requests for pet behavior help. Solving cat behavior problems and bad dog behavior can be a challenge. Some of these I address with articles explaining cat behavior (how to stop meowing, for example, or dealing with cat aggression), as well as puppy and dog behavior issues like noise phobias and separation behaviors.

Some pet behavior challenges have solutions through reading books and articles, others via phone call advice, and more serious issues (dog aggression, for example) need one-on-one help. But how do the behavior experts receive training?

Dog Hot Spots & Home Remedies

Dog hot spots often happen during both the spring and fall shedding season and are the bane of many dogs’ existence. Some develop hot spots all year long, especially those with very thick, wooly coats. Have your dogs ever suffered from hot spots?

Fortunately, hot spots are not a problem for cats. Kitties, though, do have their own issues with shedding and hairballs. Bathing cats can help with that.

When dog hot spots are a chronic problem, it can be aggravating and frustrating for pet owners. And painful for the dog! While severe problems need veterinary attention, home remedies for dog hot spots often help enormously. Here’s what you need to know.

Memorial Day & National K9 Veteran’s Day

Memorial Day honors the American men and women who have lost their lives while serving in the military. It originally honored those who died in the Civil War, and now honors those who died in any war. It is also known as Decoration Day. This holiday differs from Veterans’ Day which honors all those who served in the military.

There is no Memorial Day for the brave military K9s who served and lost their lives, often heroically saving their human partners. I can’t imagine the bond that must exist between the soldier and his or her war dog—they share things and stand against danger to protect the rest of us against horrors we don’t want to think about. And because of them, we don’t have to worry about such things. Thank you.

I’m eternally grateful to those who sacrifice for our freedom. Losing a beloved animal companion anytime cuts deep. It must be horrific to lose a comrade-in-arms, including those with four feet and fur.

And since I focus on pet issues, I want to shine a light on the dogs of the military. There is a National K9s Veteran’s Day on March 13, too. But here’s an excerpt from my book DOG LIFE  to shine a light on military dogs through the ages.

What to Do About Dog Choking & Cat Choking: First Aid & Pet Heimlich Help

Have your pets ever choked on something they chew? Shadow-Pup loves to chew up inedible objects, no matter how much we supervise. Learn how to administer the pet Heimlich to save a life!

When Karma-Kat came to live with us, that put lots of cat toys within Magical-Dawg’s reach. Seren had never been too keen on such things and she was already nine years old when Magic came as a puppy. He loved to swipe Seren’s “sparkle-balls” and ended up with sparkly poop. Once Karma’s toys added to the kitty quotient, the big ol’ dog had a field day seeing how many cat toys he could stuff into his jaws.

Bravo played with rocks. And the new puppy Shadow loves to chew sticks. He’s already got one caught in the roof of his mouth. That’s the perfect opportunity for choking, and a need for the pet Heimlich. I hope that we’ll never need it, though. In case you do, read on!

Please Fence Me In: Creating Good Neighbors & Keeping Dogs Safe

Do you have a dog fence? Magical-Dawg used to take off after “critters” every so often, racing around the 13-acre spread (or beyond). We eventually trained him to stay with us, even when off-leash. It would have devastated me if Magic disappeared. He was microchipped, but folks would need to catch him first.

Bravo was a very different dog. He was so good off-leash during most morning rambles and didn’t want to go too far away from us. He’d chase and play with his “big-ball” in the field, and baptize every tree and grass tussock. And once he lost his leg, he couldn’t get out the back fenced area even if he’d wanted to.

 Shadow-Pup, though, takes after Magical-Dawg. He’s so small, not even the fenced back area keeps him contained. He also likes to dig, so we needed to address possible escapes. A fence is a dog’s best friend!

Why Cats Fight! What to Do About Cat Fighting

How do you stop a cat fight? And how do you know if the cat fighting turns serious—rather than just kitten play? Shadow-Pup thinks it’s great fun to chase and wrestle with Karma-Kat. We supervise, of course, and interrupt the play should one or the other object.

There are many kinds of cat aggression, and many are perfectly normal behaviors. Certainly, it’s not fair to you or the cats to allow cats to fight. Learn how to recognize the potential and reasons behind cat aggression and fighting cats, and what you can do.

How to Make Pets Vomit

A dog vomits more easily than nearly any other creature. So why in the world would a pet parent want to make pets vomit? When dogs or cats eat the wrong thing that could cause harm, you can save your pets’ lives by inducing vomiting. 

Pets vomit for all kinds of reasons. Sometimes it’s because of illness, while other times the dog vomiting or cat hairball upchuck is more innocuous. Some pets eat grass to induce vomiting, or they get into dangerous candy that makes them sick. However, sometimes making pets vomit means life or death. That means you need to know how to make pets vomit.
