When a cat sniff something , it sometimes take on a foreign facial expression , seemingly shocked by the flavor of a stinky object .
So why do computed tomography really make this unearthly " malodor face ? " change by reversal out it has nothing to do with unpleasant odors — it ’s actually a sign that they ’re analyzing chemic signals in their environment .
This Bengal cat is sensing pheromones with its sensitive Jacobson’s organ.
Many animals , including wild anddomestic cats , release pheromones — chemical signal used for communicating between members of the same species . To detect and trace these invisible message , our feline friends rely on a particular sensorial organ in the roof of their mouths call the vomeronasal organ or " Jacobson ’s harmonium . "
This organ is freestanding from the olfactory arrangement ( i.e. the olfactory organ ) , which detects odors but not pheromones , Alex Taylor , cat wellbeing and conduct consultant atInternational Cat Care , severalise Live Science in an email .
When a cat run into pheromone , it march them differently from smell . The khat instinctively opens its oral fissure slightly , lips coil back , displaying a behaviour phone the " Flehmen response . " This locution makes it easier for pheromone molecules to reach the vomeronasal organ , enhancing the computed axial tomography ’s power to sense important chemical cues .

" This can see like the Caterpillar is grimace , but there is no worked up aspect to this conduct – the cat is just notice and processing pheromone , " Taylor said .

Cats use pheromones to pass various subject matter : they can utilise them to mark territory without engaging in fighting or to strengthen the James Bond between mothers and kitten , Taylor explained . Pheromones also convey information about sexual status , indicate when a quat is in heat , saidMikel Delgado , a senior research scientist at Purdue University Veterinary College of Medicine in Indiana .
Pheromones are secrete by specialized glands located in multiple country around a khat ’s torso , including the chin , cheeks , the place between eyes and ears , edges of the lips , base of the tail assembly , around the genitals and anus , between the paws and between the teats , Taylor said .
When cats rub their face on furniture , scratch surface , spray weewee or defecate , they give behind chemical substance messages for other cats , Delgado told Live Science in an email . by and by , other cats use their vomeronasal reed organ to analyze these scent marks and conglomerate information about their feline neighbors .
During the Flehmen response , pheromone molecules enter a computed axial tomography ’s mouth — either through licking or aspiration — and dissolve in spit . They then move around through two passages in the ceiling of the oral fissure , known as the nasopalatine ducts , which lead to the pair of fluid - satiate sacs that make up the vomeronasal harmonium , Taylor said .
When pheromone molecules reach the vomeronasal organ , they trigger nerve signals that travel to specific areas of the nous , namely the amygdala region of the hypothalamus and a neighborhood that controls intimate , feeding and social behaviors , Taylor said . In this agency , chemical cues pick up by the vomeronasal organ directly influence a cat ’s behavior .
Unlike odors , the signification of which is ascertain and can change with newfangled experiences , pheromones trigger natural responses . A cat does n’t call for to " learn " what a pheromone means — the noesis is hardwired into its biological science , Taylor said . While responses to pheromones are machinelike , they can still be influenced by factors such as a cat ’s development , surroundings , past experience , and internal State Department like endocrine tier , according to a review published in theJournal of Comparative Physiology A.
The vomeronasal organ is n’t unique to cats . A range of animals , everything from rodents to reptiles , also use this second sense of smelling to notice pheromone .
" The advantage of the Jacobson ’s organ is that animals can detect a wider kitchen range of molecules in the surround than brute lacking that organ,“Jonathan Losos , an evolutionary biologist at Washington University in St. Louis , severalize Live Science in an email .

" Dogs are renowned for their keen sensory faculty of smell , but that refers to their capabilities in their nasal passing , " Losos say . " Cats have three times as many dissimilar types of scent detectors in the Jacobson ’s organ as dogs , which leads some experts to suggest that , overall , guy good sense of smell may be comparable to that of dogs . "
An evolutionary remnant of the vomeronasal organ , is even found inhumanswithin the nasal septum , but there ’s no strong grounds that this vestigial version play a role in chemical communicating today .
For cats however , the vomeronasal organ is a knock-down tool that enables them to render important societal information in their environment . To quote Scottish novelist and poet Sir Walter Scott : " Cats are a mystic form of folk . There is more passing in their minds than we are cognisant of . "
