If you have noticed, your pet cat enjoys smelling your nose and mouth. Weird. Isn’t it? But actually, what do you expect from an animal that has 45-200 million olfactory receptors? People often complain about how cats smell when they eat something or sleep. They try to grab the face using their paws to smell. Whether you feel annoyed or not, they are never going to stop.

Well, the reason behind this action is that they are driven by instincts and a great sense of smell. They use the olfactory receptors even to sense the very smallest aroma that’s in the air. Also, cats use the scent as stimuli around them. Hence, they interpret the smell as a movement. By reading this article, you can discover the reasons behind this strange behavior of smelling your breath.

The science behind cat smelling

Since we have mentioned the olfactory receptors in cats above, you must know the acute information of what causes them stimuli. The epithelium is a tissue type that is responsible for cats to have a great sense of smell. These issues are available on the outer surface of the cat’s body at different parts. They will be covering the olfactory system, which triggers them to sense the smell.

Consider a human being of an average weight of 60kgs, and the smelling sensory is available in the surface area of 10cm2. In cats that weigh 30kgs, these smelling senses are present in 20cm2. That is why they tend to sniff around most often.

Now, this is proven right with the comparison of dogs and cats. As you know, commonly dogs are known for sniffing and smelling. Even humans use this as a tool to find lost objects or people, with the help of trained dogs. The reason behind it is that dogs have this epithelium more than cats.

Also, you must know that both cats and dogs have these olfactory sensors all over the body in higher proportion compared to human beings. It is because humans have a flat body surface, and bones are protruded everywhere. While in the case of cats and dogs, they have the bones curling and folding; hence, the placement of epithelium seems to be everywhere in the body.

Sense of Smell in Cats

The studies published earlier in 2017 came up with the theory that the cats’ smell is merely not a number game. It is understood that cats also possess scent receptor proteins in them, which allows them to differentiate the smell in the environment. This protein is available in humans as two variants while cats have like thirty.

Hence, cats use the sense of smell naturally to extract information from the environment. Especially when it comes to the owners, they can analyze every particular scent that is changing every moment. When they feel dangerous or find something predatory, the advanced sensors in them are open, and they can taste the substance and analyze the smell. It may sound weird, but it can happen with any cat.

In this technique, they keep their nostrils closed and inhale near the object with their mouth open. In this way, they can use the flehmen tissue to understand the smell. But this is only used when they feel the danger in the surrounding or wanted to find their potential mate.

Hence, when the cats try to smell your breath, there is no need to worry. They are merely and unavoidably trying to extract information from your surroundings. However, there are other times when cats smell your face surprisingly.

Here is a table that will help you understand why cats try to smell your breath.
