According to the latest research, cats will use their ears to psychologically guess the location of their owners, even if these owners are not in its line of sight, the cat will be in its psychology, that is, within the scope of thought, has been closely concerned about the owner's dynamics.
According to the researchers' research, it was found that the cat would judge the trajectory of its owner's actions through his hearing and in his thoughts. This means that the cat, even if he doesn't see you moving, will imagine which room (location) you are in through his judgment of the sound.

And experiments have proved that most cats, in fact, will be very surprised, because their owners seem to move from one room to another room, without making any sound, this is because the sound of our movement, often changes, such as the material of slippers, bare feet, carpets, floor materials will change, cats need to adapt for a period of time, need to get used to it to recognize these sounds, in order to more accurately use sound to draw the owner's map location in his mind.
That way, it can keep an eye on you by not using your eyes. People who are so commonly believe that cats are not as concerned with their owners as dogs, but it turns out that they are always concerned about your presence in their hearts and spirits. And, researchers think it's actually a very advanced ability that is the foundation of creativity and imagination.
When researchers observed the apparent mental mapping ability in cats, they thought that although cats slept most of the time, in fact the cat may be thinking a lot about problems every day, and it is busier than you think.
Simply put, when we are in the room, or when they need us, for example, our pet cat "potato", when he is hungry, he will find me for the first time, even if he sleeps in another room, it is not unusual to think about it now, because he has long been prejudged through hearing, in its mind, almost will not appear, the cat in many rooms, looking for the owner of the situation, then this is also the embodiment of the cat's wisdom.
Of course, the premise of this is that you have to have many rooms.
