About 2500 years ago.  Foxes and Mice lived in different parts of the planet and didn't even know about each other.  Then the rats came into where the Mice were living and drove them out of their land.  After about 10 years of searching for a place to live,  they entered fox territory.  The mice got nervous and they didn't know what would happen in this strange land.  About 2 weeks later they came to a rather large village in the middle of the fox territory.  By now the mice had grown weak and hungry.  The foxes in the village didn't understand what was going on, but they took them into their village and nursed the mice back to health.  A few days later, the leader came back to the village from a hunt for food.  The leader was one of the first golden foxes.  When the female mice saw him, they all thought that he was cute.  One of the female mice (a white mouse) came up to him and gave him a kiss.  The mice had grown fond of the foxes and vice-versa.  The leader made the group of mice honorary citizens of the town and he took the white mouse to be his mate.  This was the beginning of the fox/mouse love affair.
