Three Samurai Cats: A Story from Japan — Eric A. Kimmel

After a rat takes over his castle, a canine old lord knows there is only one way to get rid of such a bully. He needs a samurai fast-a samurai cat!
A fierce samurai arrives and draws his sword, ready to vanquish the upstart rodent. He charges toward the venomous vermin...
Splat!
The defeated cat slinks away. Next, a samurai cat in full armor takes on the job.
Splat!
The second cat slinks away. Then an old, toothless, ragged-tailed cat limps to the castle, promising to chase away the invader. What could this ancient cat possibly offer a humiliated dog with a giant pest problem on his paws?
