The cartoon is unusual in that it mixes a new soundtrack by Bill Lava with music by Carl Stalling (while alive in 1964, he had retired six years earlier), which is heard during the original shorts that make up this cartoon. That results in a schizophrenic soundtrack (whether this was intentional, given the plot of a mentally unbalanced Sylvester visiting a psychiatrist, isn't known, but it is possible). Even more unusual is that certain prints of the cartoon contain stock music pieces by Philip Green that play over numerous areas of the cartoon without removing the old soundtrack, creating a rather dissonant, overbearing "new" soundtrack.
