There once was a homeless cat named Cathy. She wanted to make herself strong. So she was hard-working and could run fast later. She always walked around her neighborhood (街区) to catch mice and she had enough food. When the weather was warm, she could lie in the sun and enjoy a relaxing and happy life.
One day, a girl moved into Cathy's neighborhood. She was a kind girl and noticed (注意到) that Cathy was homeless. Every day she put food around Cathy's house, an old box. The food was delicious and plentiful. So Cathy didn't have to go out and catch mice by herself anymore. Every day she did nothing and just waited for her delicious food. As time went on, she got fatter and fatter. She couldn't run very fast. But what did this have to do with her? She had enough food now!
But she didn't know why this kind girl suddenly moved away one day. Cathy had no more food to eat. At the same time, she was too fat to catch mice. The neighbors complained (抱怨) that there were some mice in the neighborhood. Cathy's miserable (悲惨的) life began.
She really wished she hadn't met that kind girl. Her kindness made Cathy lose the aim (目标) of living hard. So we should not lose our ability (能力) in the easy and comfortable life, or we will be miserable like Cathy!
