Our cat can knock loudly at the door after a walk! I wondered for a long time what she was doing, and finally watched it. She climbs on the seat of a bicycle standing at the door, holds her legs in the wall and crumbles. The wheel knocks on the door, we open, the cat at home.
One day there was no bicycle at the door in the evening (the husband went on it for shopping). The knock on the door continued. I open. There is a neighbor’s girl and my cat. “Your cat? She wanted to go home so much that she knocked on our bike at our door. And then a complaint knocked at your door.”
It seems to me that from the doorbell this cat is held only by the height of its location.
