Sense of cat’s smell
A domestic cat’s sense of smell is about fourteen times as strong as humans, cats have twice as many receptors in the olfactory epithelium as humans.
The human nose has about 5 million olfactory receptors, microscopic proteins that allow us to detect odours, although cats are not as effective as dogs, they have 149 million and 300 million receptors to cats which has 45 million to 80 million receptors.
Cats are like dogs they use their sense of smell to gather information, including information about us their human scent is comforting to them, their nose is an important sense organ.
Cats have 200 million scent receptors in their nasal cavity, most breed of dogs do not have even close that number. Cat’s sense of smell guides her to their prey, tells her if food is edible or toxic, tells her where you have been and even helps her find her way home.
Outdoor cats mark their territory with urine or feces, this is to inform them of an intruder, also can detect a female cat in heat, when females are ready to mate, they release certain pheromones detectable only to the feline nose.
Mutual sniffing is a feline greeting when they sniff each other’s noses sides and butts, and then go about their activities together, the cat’s sense of smell stimulates her appetite a cat has very few taste receptors on their tongues compared to people, therefore smell rather than taste is what stimulates them. In cases where cats cannot smell their food, they will go off food.
Since cat’s have very strong sensitive noses very strong odours are distasteful and painful, products that smell of citrus and tea tree some cats dislike.
Cat’s noses often reflect the colour of their fur like black cats have black noses, white cats have pink noses, orange cats have orange noses, grey cats have grey noses, multicoloured cats have multicoloured noses and so on.
Every cat is unique, noses are like fingerprints they form their personalities and have unique patterns, bumps and ridges.
When a cat licks its nose, it removes any residue such as pollen that may linger and interfere with the cat’s need to smell each other and things.
