The four moreau novels are set in a postwar United States where there is a growing population of over ten million non-humans, the leftovers of wartime genetic engineering. The books revolve around politics, conspiracy, prejudice, and the attempts abnormal characters make to live a normal life.
These books have developed a bit of a following within "furry fandom," the subclass of fandom that's usually associated with cartoons and animation, the primary source for images of anthropomorphic animals.

If you don't know what a "furry" is, here are a few links that expound on the matter:
