Why Rabbits Have Got Short Tails

Once there lived a Rabbit. His name was Bunny. He was grey and big, bigger than his Brother Bonny. But he had no tail. And he wanted to have a long tail, longer than that of Mrs Fox.
One day Bunny went for a walk. He saw Mrs Fox.
"Hello, Mrs Fox," he said. "Where are you going?"
"I'm going shopping."
"What are you going to buy?"
"I'm going to buy a tail."
"But you've got a tail! I think it's the longest and the most beautiful tail!"
"Well, but I want a new one, a longer and more beautiful one than my old tail."
"Oh, please, Mrs Fox, buy a tail for me too. Look at me, I haven't got a tail."
"OK," said the Fox and ran to the shop.
In the shop Mrs Fox bought only one tail. It was a beautiful long red tail, it was longer and more beautiful than her old tail.
She ran back home. On the way home she saw Brother Rabbit. Bunny looked at the Fox's tail and said, "Oh, what a beautiful tail you've got. And where is my tail?"
"I'm sorry," said the Fox, "but there wasn't any tail for you."
Poor little Bunny! He was so sorry. Mrs Fox hadn't bought a new tail for him!
A Dog who was running by came up to Bunny and said: "What's the matter with you?"
"Oh," said Bunny, "all the animals have got long, beautiful tails but I haven't got a tail!"
"Poor little Bunny!" said the Dog.
At that time a Cat was running by.
"Bunny! I've got an idea. I think I know how to help you!" And he ran after the Cat, bit off a little piece of the Cat's tail and gave it to Bunny. Bunny was happy!
"Thank you very much," he said. "Now I've got a tail, too... It's a very short tail, but it's a tail."
That's why rabbits have got short tails.
