A paranoid Sylvester flashes back to earlier parts of his life while describing to a psychiatrist that he thinks Hippety Hopper is out to get him.
The cartoon is unusual in that it mixes a new soundtrack by Bill Lava with music by Carl Stalling (while he was alive in 1964, he had retired six years earlier), which is heard during the original shorts that make up this cartoon. This 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 a stock music piece by Philip Green that plays over numerous areas of the cartoon without removing the old soundtrack, creating a rather dissonant, overbearing "new" soundtrack.
- On ABC, the flashback from "The Slap-Hoppy Mouse" where Sylvester repeatedly attempts to load a rifle "frontier-style" (and gets blasted) was cut.
- This was the last theatrical appearance of both Hippety Hopper and Sylvester Junior.
- A small scene from this cartoon would be used in the Thanksgiving special, Bugs Bunny's Thanksgiving Diet.
- This short is essentially a clip show containing portions of earlier cartoons such as "Who's Kitten Who?", "Cats A-weigh!", and "The Slap-Hoppy Mouse".
