"Pussy-cat Mew" is one of the 22 selections in L. Frank Baum's 1897 collection Mother Goose in Prose. It is, curiously, the one piece in the book that is written in verse instead of prose. In it, Baum expands the nursery rhyme about the cat that goes to London to visit the Queen.
In his Introduction to the collection, Baum notes the report that the original rhyme was composed by Percy Bysshe Shelley, without trying to affirm or deny the attribution.
"Pussy-cat Mew" is one of the minority of fables in Baum's collection in which animals can talk. (See "Hickory, Dickory, Dock," "The Black Sheep," and "Little Bun Rabbit.") The protagonist cat talks to another cat and to her human mistress.
