While the mice in this animated short don't act like Mickey, they sure look like him. Some say that imitation is the sincerest form of flattery...to me it just seems like a cheap attempt by Looney Tunes to ripoff the Mouse! Like the early Looney Tunes/Merrie Melodies animated shorts, this one was supervised by the (uggh) team of Harmon and Ising--whose cutesy style was really big during the 30s and early 40s. While popular at the time, today their cartoons for Merrie Melodies and MGM look, well, pretty dreadful. It isn't that the animation is so bad, but the stories are just so saccharine and lack any of the edge later cartoons would have. Fortunately, for a Harmon/Ising production, this is among the least cutesy of their cartoons. Now this isn't saying it's good, because it really isn't. I only gave this film a 5 because relative to other films of the day, it was pretty average--though significantly less interesting than a real Mickey Mouse cartoon of the day.
The film consists of a raspy cat trying to kill the poor mice and, naturally, the mice prevailing (I bet you didn't see THAT coming, huh?!). In addition, there is some singing at the end because I think Harmon/Ising were contractually obligated to irritate the audiences with these awful songs.
Of interest to film historians (after all, this film was somehow nominated for an Oscar) and masochistic film viewers who like painfully unfunny cartoons.
