Since I don't know when, the kitten has become a real homebody. As long as there is nothing to do to get out, I don't want to go out. It's good to surf the Internet or exercise in the house, or cook a few dishes. In short, I just don't want to go out. The curtains are always pulled low, so every time a friend comes, they will question: what are you doing that makes it completely airtight??
