Long ago there was a cat...

Very cute take on this classic camp song, which has such deathless verses as

Once I had a little squirrel
And all she ate was nuts,
And when those little squirrelies came
They came with great big butts!

Once I had a little dog
And all she ate was cans
And when those puppies came
They came in Ford sedans!

When Mary had a little lamb
The doctor was surprised
When Old MacDonald had a farm
The doctor nearly died!
