Flippy and Flop

Flippy and Flop are a cartoon yellow canary and black-and-white cat duo that appeared in theatrical shorts from 1945 to 1947 by Screen Gems for Columbia Pictures. The canary, Flippy, made his debut in 1945's Dog Cat and Canary. Starting in 1946, Flippy partnered with Flop, a cartoon cat.

Plot
The antics of the two characters were similar to that of Tweety and Sylvester of Warner Bros. However, unlike Tweety, Flippy had to rely on Sam the household dog to protect him from Flop. The two characters only appeared in four cartoons together before Screen Gems was replaced by United Productions of America in 1948, with Screen Gems' final cartoon releasing the following year. Their popularity never reached that of Columbia's biggest cartoon stars, The Fox and the Crow. Flippy (renamed "Flippity") and Flop lived on only in comic books published by DC Comics until 1962.

Voices
The characters were mostly voiced by Harry E. Lang. (Flop also has a speaking role in Cagey Bird and Silent Tweetment by Frank Graham, and Flippy in the end of Big House Blues by Bill Shaw.)
