Not only dogs, but also cats love to greet their owners at the door.
But how do they know that the owners will be home soon?
How does a cat know when its owner is coming?
Firstly, if the owner leaves and returns at approximately the same time every day, the cat will not have any trouble remembering this.
Secondly, cats remember the smell of their owner and the sound of his steps.
A cat's hearing is several times better than a human's, so it is not at all difficult for it to "figure out" its owner approaching the house.
Cats also have a well-developed sense of smell; they can detect a scent from a distance of up to 20 meters.
