Read the selection below from the poem “The King Sends Three Cats to Guinevere” by Marjorie Allen Seiffert and answer the question that follows. I send you three grey cats with gifts—
(For uniformity of metaphor,
Since Bacchus, Satan, and the Hangman
Are not contemporaneous in my mythology)
I send you three grey cats with gifts,
Queen Guinevere,
To warn you, sleekly, silently
To pay the forfeit.
