My extremely curious cat Merritt (she’s a busy-body calico) is sniffing one thing once more, which isn’t sudden. What is sudden is when she sniffs an object and appears up together with her lips curled simply moderately again. To start with, I believed it used to be merely a glance of shock or wonder over what she had simply smelled. However that “cat smelly face” has a systematic title, flehmen, and cats aren’t the one ones who do it. So, what’s a cat flehmen reaction and why does it occur? Let’s have a look. 

What does a cat flehmen reaction seem like?

I’d very best describe the cat flehmen reaction as a glance of utter, lip-curling disgust / confusion / worry that elicits some true laugh-out-loud reactions from the cat oldsters that catch their kitties doing it (see Merritt’s face above all through her — supervised and ribbon-less! — prance in our discarded vacation present wrap). “The flehmen reaction seems like a cat frozen together with her mouth open,” Dr. Sasha Gibbons of Just Cats Veterinary Hospital in Stamford, Connecticut, explains. “Occasionally, cats will roll their lips again over the tooth as smartly, which will resemble a sneer.”

What’s a cat flehmen reaction?

My cats have some sturdy reviews and “pooh pooh” at the entirety from area visitors to new toys. However, the cat smelly face isn’t essentially a snooty sneer — it’s if truth be told far more clinical than that. “The flehmen reaction is a kind of sniffing, however as an alternative of the use of their nostrils, cats inhale the air thru their open mouths,” Dr. Gibbons says.

Anthrozoologist John Bradshaw tells Slate that the flehmen reaction opens up two small ducts, sometimes called the nasopalatine canals, at the roof of an animal’s mouth in the back of the incisors. The ones ducts then pass during the roof of the mouth and sign up for up with the vomeronasal organ (a.okay.a. the Jacobson’s organ), which consistent with Bradshaw, purposes as an auxiliary olfactory bulb of types.

Slate additionally stories that some scientists imagine the flehmen reaction does one thing that’s between the sense of scent and style (so cats, type of DO have a 6th sense!). The ducts comprise saliva, that means that no matter is going in should be voluntarily introduced as much as the vomeronasal organ. In different phrases, flehmen isn’t an automated method to soak up smells, as one does thru respiring.

The thing is going directly to give an explanation for that cats if truth be told have higher vomeronasal organs than canines. A mean area cat has 30 other receptors in that organ, while a hound canine has a measly 9.

Why do cats do it?

“Cats use the flehmen reaction to hit upon chemical stimuli, similar to pheromones, which are found in urine and feces, or spaces that cats have marked with smell glands,” Dr. Gibbons says.

However right here’s a fascinating reality — male cats in most cases flehmen greater than feminine cats! “Male cats use the flehmen reaction with regards to mating,” Dr. Gibbons explains. “Scents can assist point out compatibility and if timing is correct.”

After all, there are exceptions, as with my cats. I catch Merritt, my feminine kitty, exhibiting a flehmen reaction to one thing about as soon as an afternoon. I’ve simplest observed my male cat, Gabby, flehmen a handful of occasions within the 5 years we’ve had him.

Are cats the one ones who show a flehmen reaction?

Nope! “Along side home cats, massive cats similar to lions and tigers, additionally use the flehmen reaction,” Dr. Gibbons tells us. “Out of doors of the cat circle of relatives, horses, giraffes, buffalos, goats and llamas have additionally been observed demonstrating the flehmen reaction.” Slate reports that people used to have the vomeronasal organs essential for a flehmen reaction — however they were given phased out within the evolutionary procedure. Bummer!

Will have to you ever be curious about a cat flehmen reaction?

Fortunately, the solution is a undeniable no. “As humorous as it’s going to glance, there is not any hurt to a cat displaying a flehmen reaction,” Dr. Gibbons advises. So, experience the ones cat smelly faces (and take some footage — there don’t seem to be sufficient just right #flehmen pics that includes cats on Instagram!). They’re utterly customary and you have got not anything to fret about!
