A video of a puppy sniffing its cat brother has gone viral on TikTok, with over 3.2 million views.
In the video posted by @ladynort18, a puppy can be seen approaching a cat and purring on its back, then retching. The caption read, “When your puppy notices a cat’s butthole for the first time.”
Smell is an important sense for most animals, and they are able to send and receive messages by producing specific smells. Research suggests that elephants have the best sense of smell of any animal, but dogs and cats are up there too.
When two people meet, they check body language and can judge looks, facial expressions and tone of voice to determine if a person is trustworthy before acting accordingly.
Dogs do the same thing, according to California-based VCA Animal Hospitals. Its website states that “dogs may not talk, shake hands, or hug like humans, but they assess each other and gather a lot of information from body language. Are the ears back? Are the dogs waving? tail? Are the hackles raised?”
The American Kennel Club website states that a dog’s sense of smell is 10,000 times greater than a human’s and that “dogs’ olfactory curiosity is about gathering information and welcoming.”
VCA Animal Hospitals also points out that “a cat’s sense of smell is more advanced than ours. Compared to humans, cats have a sense of smell that is 14 times more sensitive. The human nose has about 5 millions of olfactory receptors that detect odors, while a cat’s nose has 45 to 80 (possibly up to 200) million odor receptors.”
Cats also have a unique feature called Jacobson’s organ, which is inside the nasal cavity “and opens into the roof of the mouth, right behind the upper incisors,” according to the VCA.
“This unique organ serves as a secondary olfactory system and detects specific chemicals using nerves that lead directly to the brain,” says the VCA. “Unlike the olfactory cells of the nose, the odor receptors of Jacobson’s organ do not respond to ordinary odors. Jacobson’s receptors pick up chemical substances that have no odor.
TikTok users really enjoyed the video, with one, Dawn, commenting, “My son and I are on our 30th watch and have to stop wiping my tears. This is a winner on TikTok now.”
Janemvv wrote, “omg, this made me laugh so hard I cried.” And Goddess Kreseda said: “Lmaaaooo! I’m crying!!
