His wife says, “Can’t you eat without her?” So the meal begins without the cat. Before lunch is over, the cat rushes into the room and jumps onto the chair quickly. She has two mice in her mouth, and before anyone can stop her, she drops(扔下) one into her own plate, and the other into her master’s plate. “Dear me!” cries the woman, “A mouse is in your plate!” “Hush(安静)!” says her husband. “This shows that she is a nice cat.
