There’s a lot more to a cat nose and a cat sense of smell than you might think. Yes, the cat nose is a cute little spot to “boop,” but that colorful little nugget plays a huge role in your kitty’s life. Here’s how.
Cats have 200 million scent receptors in their nasal cavity. Most breeds of dogs don’t have even close to that number. Your cat’s sense of smell guides her to prey, tells her if food is edible or toxic, tells her where you’ve been, and even helps her find her home if she gets lost.
Outdoor cats mark their territory with urine or feces, so if your cat goes outdoors, she can tell if anyone’s been intruding in her space. The cat sense of smell to can detect female cats in heat; cats who are ready to mate release certain pheromones detectable only to the feline nose.
Cats have very few taste receptors on their tongues compared to people, so it’s the smell rather than the flavor that stimulates her sense of hunger. That’s a big part of the reason why cats with respiratory infections or other nasal blockages stop eating: If they can’t smell their food, they won’t get hungry.
If you’ve watched two feline friends approach each other, sniff one another’s noses, sides and butts, and then go on about their business together, you’ve watched the feline equivalent of, “Hey, how’s it going? Whatcha been up to?”
Because cats’ noses are so sensitive, very strong odors are distasteful if not outright painful. This is one reason I recommend against using scented cat litter: The smell might be nice to you, but it could be overwhelming for your feline friend’s nose. Cats are also known to dislike the smell of citrus and tea tree (melaleuca) oil.
Black cats have black noses, white cats have pink noses, orange cats have orange noses, gray cats have gray noses and so on. And if your cat is multicolored, she might just have a multicolored nose, too. Some kitties also have nose freckles, and some cats have noticeable nose color changes.
Every cat’s nose has a unique pattern of bumps and ridges, just like humans’ fingerprints. There has apparently been some talk about using nose prints as a form of identification, but good luck with getting your cat to tolerate having her nose inked and pressed against a piece of paper!
Some say it’s like a reset button for the cat sense of smell: licking the nose removes any residue such as pollen that may linger and interfere with the cat’s need to smell other things. Others say it’s a “tell” that a cat is anxious or nervous and has no connection with the sense of smell at all.
Tell us: Do you have any weird questions about the cat nose or the cat sense of smell?

He has a smoky gray coat, 12+ pounds, tall and on the slender side. He is a hunter, playful – even at age 4, and has the most amazing sense of smell I’ve ever seen in a cat. (I’ve had cats most of life and I’m over 50 years old). I’ve had times with some sort of food or snack in different rooms or had just gone grocery shopping – food still wrapped up and within minutes – he’s found at the food source sniffing or eating away. He’s fed twice daily.

Silvia Gasparini February 15, 2019 at 5:52 pm About cats licking their noses. What I heard from a number of vets is: 1. Nose-licking can take place just after a spike in anxiety, when there is no (more) immediate danger, but the situation needs watching. Horses do the same, licking and smacking their lips when they relax after an alarm, but are not yet sure all is well. 2. Nausea: not only immediately before throwing up, but also in case of some chronic or developing conditions (kidney failure, intestinal lymphoma…) I’d like to add the possibility that in both these cases, and also perhaps while hunting, a cat may lich nose in order to raise humidity of the mucosa and so favour a better perception of faint smells (or attempt elimination of the bad taste from toxins in case of illness): they say scent dogs work better in humid (not wet) weather. Reply Temple February 13, 2019 at 10:41 am Is there a way to be able to tell if my cat actually cannot smell? Our last cat would be all over us in a hot minute when we’d have milk, ice cream, cheese. but I spilled a bunch of milk on the floor a few weeks ago and our new cat just walked on by like there was nothing there. Reply Eliana August 1, 2019 at 7:55 am maybe they just don’t like dairy like your other cat :) Reply John B December 26, 2019 at 3:50 pm My cat seems to have no sense of smell at all. I have offered him milk, cheese. chicken, ham, turkey, beef, and scrambled eggs — turns his nose up at them every time. Once in a rare while, when he seems interested in the chicken fresh out of the oven, I tear off a piece to see if he will eat it. If he takes a taste, I randomly toss another morsel on the floor or in his food bowl. He can’t find it to save his life. I’ve never seem even one of my dogs so scent blind. They can pick up the slightest whiff of a drumstick more than a country mile away. Yet Romo is the finest indoor/outdoor cat I’ve ever known. He refuses to use a litter box. It’s beneath his dignity. He’d rather wake me up at 3 or 4 in the morning than to take care of his business inside any corner of the house. He protects his outside borders fearlessly but is not aggressive when he roams to places God only knows where. One of the finest felines I’ve ever had the honor and pleasure of bonding with. Reply Bill Deedler April 19, 2020 at 3:29 pm How does he survive if he doesn’t eat any of that stuff? He must eat some sort of cat food, what kind – how about mice, etc… My old cat has congestion issues and hard to get to eat. Reply Ellen Linke July 9, 2020 at 10:56 pm My cat is the same. Won’t eat anything but dry cat food in her bowl. The vet said I was feeding her too much, and got a feeder to dispense food, but she can’t find the kibble when it comes out.
