What a good cat can do: don't bother the owner. A good cat won't bother the owner. During the day, when the master is working, he will play or sleep quietly. In the dead of night, even if you have unlimited energy, you won't disturb the host and let him sleep peacefully.
Good cats don't just go out. They know that if they get lost, the host will be very anxious and spend a lot of time and money looking for themselves, so they usually stay at home and don't go out casually, which is very worry-free.
