So they all sat down and had seconds and thirds,
When they saw up in a tree some hungry birds.

The birds sat still not making a sound,
Watching them picnic down on the ground.

"Why don't you join us?" asked Pat the rat.
The birds answered back, "Not with a cat!"

"But this cat's my friend, and has been for years.
See, I am a rat, and I have no fears."
