Heavy Horses

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.
