Hemingway's "Cat in the Rain" has a symbolic title that points to the theme of unsatisfied emotional desire. First of all, the American couple are isolated in their room facing the sea.

For, in her longings for the kitten, that is an anthropomorphic expression of her forlornness and need for attention and love as indicated by the repetition of the word "want," which denotes the emotional emptiness within her [want as a noun] and her desire to hold and caress a loved one and be loved [want as a verb].
