As is well known, cats mark the territory they consider theirs with urine, but this is not the only way that animals use to mark their territory.
In addition to the fact that the pet experiences pleasure by rubbing against this or that object, in this way it leaves its scent on it.
By the way, this technique also works in relation to a person. In this way, the cat seems to leave a message: "I love you and I am happy that you are mine."
Cats resort to such actions in order to leave a scent from their cheek glands, which can be called their "calling card".
A pet that is in no hurry to hide its own excrement under a thick layer of litter in the tray literally says that it is the boss in this house. According to experts, such a radical method is most often used by those animals that are insecure about themselves.
In this case, the cat shows that he is the owner of the territory both visually - with the help of marks left by the claws, and thanks to the smell, because on his pads there are glands that emit a corresponding smell when scratching.
Finally, a pet can declare its rights to a person if it licks him thoroughly. It's all about the smell again. By the way, pets can lick not only their owner, but also other cats, thus creating a common "pride smell".
