Catstello tells the audience "If the Hays office would only let me, I'd give him the bird alright." This is a double entendre acknowledging that the Hays Code, which set the guidelines for content allowed in a motion picture, would never have allowed a movie character to "give the bird" (making an obscene sign language gesture).

First appearance of Tweety Bird. Early model sheets for this short indicated that Tweety's original name was "Orson," but no name is given in the film. After censors complained that the pink bird looked naked because he had no feathers, Tweety's color was changed to yellow.

The cats Babbitt and Catstello are obvious caricatures of Bud Abbott and Lou Costello. The name Catstello is never spoken in the film.

This marks the first appearance of Babbit and Catstello as features in Warner Bros. cartoons. It is the first appearance of three cartoons where they feature (although they make a cameo appearance in a fourth), between 1942-1946. They are not always cats in each subsequent cartoon, however.

Tedd Pierce, who provided the voice of "Babbitt", was one of the top writers in the Warner Bros. cartoon department, responsible for writing many of the studios' most fondly remembered cartoons, including Elmer's Candid Camera (1940), The Dover Boys at Pimento University or The Rivals of Roquefort Hall (1942) and Dough for the Do-Do (1949), among many others.

If you listen closely when Catstello is being pushed up the ladder he says, "Don't push me Abbot," instead of Babbit.

Babbit and Catstello appear as different animals in each of their three cartoons shorts where they featured from 1942-1946. They First appeared as cats in "A Tale of Two Kitties" (1942), as mice in "Tale of Two Mice" (1945), and finally as dogs in "The Mouse-merized Cat" (1946).
