cat and rat war!

On one side of the hill there was a rat
on the other side there was a cat.
The rat loved to chew hats
the cat loved to sleep in mats.
One day the cat attacked the rats
the rats threw hats.
The cats hit the rat leader
the mice attacked the cat leader.
The war ended in a tie
then the rats found wings to fly.
Next the war began again the mice won.
So then no cat wanted to go over the mountain.
