Let the tiger skin out and let it play for a while. After a long time, it doesn't want to go to the cage. At this time, it kept opening and closing the door in front of the tiger skin. After opening it, it shakes its hand in front of the door to let it know that it can walk back and forth at this time. Knock on the cage door when closing it to let it know that it can't get out at this time. Over and over again, it will do it by itself.
