Experts say that such behavior is a sign of friendliness, as well as a hint that the pet misses its owner.
As a result, with such an action the animal shows its joy from the meeting, for example, if a person returned home after a long day or simply woke up and can again pay attention to the cat.
It is also worth noting that the cat can thus ask for attention and food.
A cat exhibits such behavior only towards a person it trusts.
Therefore, you shouldn't scold an animal for butting. You shouldn't even raise your voice.
It is better to pet the cat, talk to it. Such communication will help to strengthen good relations with the pet.
There is another reason why a cat butts its owner.
It is possible that the four-legged animal wants to mix its usual smell with the smell of a person, for example, if the latter returned after a long absence or stroked another animal.
