"Milk Treading" is the only completely cat-centered political thriller/detective story I've ever read. The characters are all cats, dogs, and assorted rodents, and British author Nick Smith does an amazing job of capturing real cat behavior. I'd give it an A for staying in character throughout, a B for plot (as in B movies), and a B/B+ for social commentary.
Parts are gritty -- this isn't your mother's fuzzy kitty story. These cats hunt, scheme, love, and fight for their survival in a world of political intrigue and fierce territorial disputes. And it's a fun -- and funny -- novel, with a quirky, dry wit. I've bought copies for grown-up gifts and told my more adventurous friends to check it out. "Animal Farm" meets "Trainspotting," or maybe "Die Hard" meets "The Aristocats."
Corrupt politicians, illicit romance, hack journalists, venal church officials, deadly gang rumbles, slums, class conflict, catnip parties, pro wrestler-turned-celebrity, murder, mayhem, and milk treading -- this has it all!
