Two cats (one a caricature of Jimmy Durante) battle violently for the affections of a pretty girl cat, who'll dispense her favors on the one who brings her a little bird. Unfortunately for the lovestruck felines, the bird in question is a vicious little thing named Tweety.
Unfortunately the movie A Gruesome Twosome is not yet available on HBO Max.
