The rhyme is nam/sam/ram/sam/tam; tones match and verbal parallelism is maintained.
By night you have the run of the roads north and south;
you mingle with fox and lynx, one of three heroes.
Fur broidered black and white;
eyes aglitter—yellow tinged with indigo.
You steal from the plate of an honored guest,
sleep in the warmth of an old man’s undershirt.
When a sparrow or a rat struts its stuff,
you meow fiercely and embark on the hunt.
