...And The Mouse Police Never Sleeps lyrics by Jethro Tull

Muscled, black with steel-green eye
Swishing through the rye grass
With thoughts of mouse-and-apple pie.
Tail balancing at half-mast.
...And the mouse police never sleeps ---
Lying in the cherry tree.
Savage bed foot-warmer of purest feline ancestry.

Look out, little furry folk!
He's the all-night working cat.
Eats but one in every ten ---
Leaves the others on the mat.
...And the mouse police never sleeps ---
Waiting by the cellar door.
Window-box town crier;
Birth and death registrar.
With claws that rake a furrow red ---
Licensed to multilate.
From warm milk on a lazy day
To dawn patrol on hungry hate.
...No, the mouse police never sleeps ---
Climbing on the ivy.
Windy roof-top weathercock.
Warm-blooded night on a cold tile.
