Timid Tabby is a superb change of pace for the long-running Tom & Jerry series, in that we see another member of Tom's family and also for a change see Jerry get the worst of the varied encounters. George is Tom's cousin and is deathly afraid of mice, a fact Jerry exploits by scaring George all over the house. Tom, however, bashes Jerry at numerous points of the short, then teams with George to trick Jerry into thinking he's gone insane, leading to an appropriate ending.
George is voiced by Bill Thompson, which adds to the strength of the character's weakness. As George is drawn as a twin of Tom it allows the animators to animate dialogue into the design while leaving Tom mute; given the quality that neither Jerry nor Tom speak in almost every episode, allowing a character who looks like Tom to speak is an interesting angle.
