Do you know why cats always eat rats? Long long ago, the Lion King wants to name the years. They will have a meeting in the morning on January 12. The earliest to arrive will be the first. The Lion King asks the rat to tell all the animals. Everyone wants to be the first. When the rat meets the cat, the rat tells the cat the meeting is in the afternoon on January 12.
On January 12, the ox gets up very early. But on his way to the meeting, the rat sits in the ox's ear. The ox runs and runs. But at last, the rat jumps in front of the ox. The rat is the first. The ox is the second. The cat is late. It comes in the afternoon. The meeting is over. And that’s why cats always eat rats.
