Although no key signature is written, characteristic of an introductory piece for children, the tonality is C minor. The theme begins darkly in the low register. This thematic movement is likely an expression of the scene depicted in the work's title. The middle section is constructed from two whole-tone scales. The phrase "crawling smoothly" written in measure 9 means "to crawl smoothly," and this too is a descriptive element, likely representing the movements of the kitten in the title.
