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 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.
Their popularity never reached that of Columbia's biggest cartoon stars, The Fox and the Crow.
(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.
