how kangaroos got their pouch

On a bright day jamie the kangaroo went on a stroll. She bounced around ever so cheerfully. Then a cat zipped in front of jamie and tried to hide behind her. "what are you trying to do ?" said jamie " i am being chased by a mouse " said the cat.  Suddenly a small mouse came . He was wearing a small hat and a very cute top . Jamie punched the mouse and threw him far far away . "thank you !" Oh thank you how can i repay you " said the cat "no i am fine" said jamie " no i will give you a pouch ""thank very very very much"said jamie not very surprised. Years later the kangaroo kind use the pouch for their young joeys.
