Freudy Cat is a 1964 Looney Tunes animated short starring Sylvester and Sylvester Jr.. The cartoon is essentially a clip show, as a paranoid Sylvester flashes back to earlier cartoons such as Who's Kitten Who?, Cats A-Weigh, and The Slap-Hoppy Mouse while describing to a psychiatrist that he thinks Hippety Hopper is out to get him.
