The final Looney Tunes cartoon to star Sylvester until Carrotblanca (1995) and Father of the Bird (1997). However, Sylvester makes a brief cameo in A Taste of Catnip (1966).
Neither Sylvester nor Wile E. Coyote speaks in this short, which is uncharacteristic for Sylvester but normal for his partner in deviousness.
Four gags are re-used from previous Looney Tunes cartoons: The tunnel gag was first used in "Hopalong Casualty", the flat boulder and iron pellets gags were first used in "Wild About Hurry", and the cloud gag was first used in "Zoom and Bored".
Final WB cartoon where Speedy bouts with Sylvester before Daffy Duck took over in this short.
