My family lives on the sixth floor. We seldom see stray cats here. Suddenly, a stray cat barked at my door?

Cats like to run high. There is nothing to worry about when stray cats come to your sixth floor. Open the door and jump on the bed, not necessarily a stray cat, but a pet cat in the community. Usually the owner closes it at home and may jump out of the window. It is said that pigs are poor, dogs are rich, and a cat runs a pawnshop. So there's no need to struggle.
