What kinds of feelings and desires is the wife really expressing toward the end of the story "Cat in the Rain"?

The short story "Cat in the Rain" by Ernest Hemingway tells of an American couple residing in a seaside hotel in Italy. It is pouring rain, and the wife notices that down below a cat is trying to escape the rain by hiding under a table. She goes down to get it, but by the time she reaches the table, the cat is gone. After the wife has returned to her room and has expressed her frustration to her husband, a maid appears with a cat for her that the hotel manager has sent.

In the book Hemingway's Cats by Carlene Brennen, the author explains that the story "Cat in the Rain" was inspired by Hemingway's first wife Hadley's desire for a cat. The couple was living in Paris, and Hadley spent long hours alone while Hemingway was working. She wanted a kitten for company, but Hemingway thought that they were too poor to own a cat.

What Hadley really wanted was a child. She had a deep desire to be a mother. She did in fact become pregnant, and during the early months of her pregnancy she spotted a cat hiding under a table in the rain and declared, like the wife in the story, that she wanted a cat. The story was a tribute to Hadley, the loneliness she had experienced, and her longing for motherhood.

Hemingway's writing style became known as the iceberg theory, because just as most of an iceberg is hidden under the water, much of what Hemingway intended to say in a story was hidden beneath the supposedly simple language. In "Cat in the Rain," although it is never blatantly stated, the wife's pleading for a cat is expressing an underlying desire for a child.
