So he said, "Meet me at the donkey fair on Saturday. I shall sell her at that time. I shall sell my donkey to the one who will treat her most kindly."
Everybody was kind to animals in the village. So the Mullah thought out a plan. He wanted to keep his word and also to keep his donkey.
On the night before the donkey fair, the Mullah bought a piece of rope. No one had any idea why the Mullah should want a piece of rope.
On Saturday, many people in the village came to the donkey fair.
They found a cat tied with a piece of rope to the tail of the Mullah's donkey! Beside them stood the Mullah, who looked happy.
"It is true, I'll sell my donkey for a dollar," said the Mullah. "Just one thing, though. My donkey and my cat are very good friends. They must not be parted. The kind man who buys my donkey must buy my cat also."
"How much is your cat?" asked many voices.
"Oh, my cat is a very important animal," said the Mullah. "Her father caught a mouse for a king. Her mother caught a mouse for the Queen. She is one of the finest of cats. For such a great cat I want one hundred dollars."
The men laughed, and gave up the idea of owning the donkey.
