In one study, observers observed 12 domestic cats for 6 months while humans worked with the animals for 2 hours a day.

Then, each day the cat must choose one of the two images to receive a reward.

The results showed that while cats had no difficulty identifying the animals they lived with, they only identified humans 54.5% of the time.

This shows that cats cannot identify their gender just by looking at their faces.

Instead, they need other stimuli to differentiate between males and females, such as sounds and smells.

Can cats smell human hormones and odors?

Cat's The sense of smell is 14 times more sensitive than humans.

Cats have 200 million scent senses in their noses, allowing them to sense a range of human hormones and pheromones, including pregnancy chemicals and menstruation.

Understanding whether cats can smell human pheromones and hormones is critical to determining whether cats can recognize human gender.

Cats can smell the following odors:

1. Pregnancy hormones:

Pregnancy is a process that only women experience.

Some experts believe cats can sense pregnancy before the expectant mother knows.

What is more likely, however, is that cats' powerful sense of smell is capable of sensing progesterone, human chorionic gonadotropin and estrogen produced by the female body.

These hormonal changes also affect your sense of smell, which cats can detect almost immediately.

Of course, cats can sense more than just hormones.

A woman’s body heats up during pregnancy, so cats may become more clingy when a woman is pregnant and like to rub against her to keep warm.

Also, cats tend to be very gentle and affectionate towards pregnant women. This may be because they can detect the child's weak heartbeat~

Not only that, cats can also detect changes in behavior or mood. Cats can sense the sadness or unhappiness of pregnant women

Although it is not entirely clear whether cats can distinguish men and women through these pregnancy hormones, it is clear that they can recognize the unique characteristics of pregnant women~

2. Pheromones

Pheromones are natural chemicals secreted by the human body. They have no smell, but they act like hormones that trigger social responses in conspecifics.

While some cats can sniff out human pheromones, they may not quite understand them

Human pheromones have little effect on felines, but smart cats can take advantage of humans The signals sent out determine how humans are feeling - whether they are happy, sad or fearful.

Cats use pheromones to sense fear or adrenaline in humans.

So, some cats like to smell people’s armpits and crotches. This is because there are glands located in the crotch and armpits, and the glands release information about human age, gender and emotions.

Women who are menstruating or have just given birth release unique pheromones to attract cats.

So, when your cat sniffs your crotch or armpit, it's just trying to examine your scent information to find out more about you.

Human ovulation and pregnancy are effective ways for cats to differentiate between women and men~

Cats can detect when a woman is menstruating by smelling scent and hormone levels.

Cats can also detect changes in a woman's mood during her menstrual cycle.

However, cats have no concept of menstruation, because cats do not have menstruation. They just know that there seems to be something happening in the human uterus that they cannot see.
