This is almost atypically simple of Schirm's work, but it also shows his command of visuall movement within a composition. And it's just a guess, but I suspect this is a kind of tribute to a pet. Schirm was known for having one or two of a large Japanese breed called a Akita around the home. After the death of his last, Schirm seems to be content with much smaller house cats.

LATE BREAKING NEWS. No its not a tribute. It ws drawn at behest of one of the recent LA Worldcon bids, as promotion.
