When I come home from get off work every day, I find my cat waiting at the door as soon as I open the door. Do you think it has a sense of time and knows when you get off work? In fact, most of the time, it uses the sound of footsteps to judge whether the person who is about to come back is a poop scooper. Official. The frequency of vibrations is different for everyone when walking, and the cat's foot pads are very sensitive to touch. When the foot pads touch the floor, you can identify which frequency comes from the floor through the vibration frequency of the floor. Therefore, when the owner quickly When you get home, the cat will wait at the door to greet you when he hears footsteps. ​​​​​​

In addition to identifying the cat by judging the vibration frequency of the footsteps through the foot pads, cats can also be identified by smell. Cats not only have a huge number of olfactory receptors, but also have a killer "vomeronasal organ". The highly capable olfactory receptors can allow cats to identify familiar smells within a range of about 6km. Cats often rely on this ability to return home after going out. It's even easier to identify the owner's unique scent.

Cats can also recognize their owners through their voices. Japanese scientists once conducted an experiment to explore whether domestic cats could recognize their owner's voice. In the experiment, the researchers recorded the voices of the owner and a stranger, and played them in sequence out of sight of the cats. As a result, when the owner's voice was played, the cat had an obvious searching response, but when the stranger's voice was played, the response was significantly weaker. There are many, so cats can remember and recognize their owner’s voice.

Cats’ ability to recognize their owners through vision is much weaker than the previous ones. Cats’ vision is only about one-tenth that of humans, and their color recognition is also very low. The visual distance that cats can see clearly is about 6 meters. They can't see things that are too close or too far away clearly, so often facing your cats face to face will not make them remember your face. Looking at them from afar will help them remember your face.
