Answer:
I believe the poem in the question uses FL (figurative language) in an innovative way.
Step-by-step explanation:
Figurative language refers to techniques used by writers in which they employ words with meanings that differ from their original ones. That is what we have in the poem "The Night is a Big Black Cat." Notice how every single line uses a metaphor. The night is being compared to a black cat, the moon to the cat's eyes, the stars to mice, and the sky to a field. Normally, authors do not use a metaphor in every line. And, in this case, the metaphors make the poem vivid and playful. We can't help but imagine the black cat chasing mice in a field and, because of the comparison, think of the night as if it chases the stars.
