A menace exists in the form of the gambling bug - biting men and making them bet over all manner of things. A cat wisely avoids trouble with a large dog, until he is bitten by the bug and starts to play cards against the dog with pain as the stakes.
I watched this as a double bill with quite a good Tweety Pie cartoon. However I dipped when I noticed that this had none of the big characters in it - although the cat and the dog both look like skinny versions of more famous characters! The plot starts out with deadbeat men showing the down side of gambling by having them look pathetic etc. Then we progress to the cat and dog story where the cat faces repeated punishment for his desire to play (and lose) at gin.
It isn't very funny and really just feels like a moral message against gambling (which is what it). However I didn't feel like they had done themselves justice and that the message had maybe overpowered the makers and hence they struggled to come up with clever ideas to make it worth watching.
As a throwback piece of public service humour this is worth a watch but really, there are much better Mel Blanc cartoons out there to watch.
