Genius of the Species

The story is set in the Soviet Union where a rat problem is getting out of control due to the laziness of cats. This problem is solved by a government program to use artificial means to raise the intelligence of cats to an IQ of 20.2 so that they can be taught Marxism and subsequently realize catching rats is for the greater good. However due to a calculation error on part of the scientist responsible for this programe the cats end up with an IQ of 202 rather then 20.2. With this superior intellect cats become the dominant species in the Communist world.
