Recently explained to the cat that he is like eating for nothing, and there is no point in him, only on the table at night he gathers nuts. It would be time for him to live on the street. After that, the cat strangely began to sleep at the doorstep at the entrance to the apartment. I was able to explain his behavior only by the fact that the cat arranged to guard the apartment, and with all his appearance showed his benefit, only not to live on the street. But the anger at the table did not stop.
