It takes a while for the decent gags to kick in, but when they do The Flying Cat is incredibly funny stuff.
The action starts with Tom eyeing up a pet canary in a cage, who he intends to turn into a snack. On seeing Tom make off with the cage, Jerry decides to lend the little bird a hand, and Tom chases the mouse as a result. Fortunately for Jerry, the canary isn't as helpless as he seems, and teams up with Jerry to turn the tables on Tom. So far, so predictable
Where the cartoon really gets funny is when Tom becomes entangled in a corset, the material forming a pair of wings with which Tom is able to fly. While this is extremely far-fetched, even for a Tom and Jerry caper, it does lead to some of the funniest moments in the series so far. Tom quickly masters the art of flying and is able to chase both Jerry and the bird, zooming after them at high speed.
Of course, flight isn't without its hazards, and Tom find himself coming a cropper in a variety of painful ways, the most excruciating being when he lands with such great force on a tree (legs apart, the trunk hitting him in the crotch) that the tree is sawn in two. Yeeeoowch!
7.5 out of 10 overall, but everything after Tom learning to fly is easily worth an 8.
