Astrosaurs. Cows In Action. Ninja Meerkats. Spy Dog. If you happen to be under nine, you’re spoiled for choice in the anthropomorphic literature department, with a range of sci-fi, adventure and action stories starring a whole zoo of creatures. There’s even alternate history: the Spartapuss series explores a feline Rome ruled by Emperor Catligula, while Beowuff, by the same author, applies the principle to doggy Vikings. You may already have guessed that none of these works take themselves terribly seriously. Expect an onslaught of appalling animal-related puns and silly names (the leader of the Pigs in Planes rejoices in the name of Peter Porker, while the ranks of the Space Penguins include Fuzz Allgrin and Splash Gordon). The action usually revolves around a crack squad of heroic critters saving the day with their collective abilities.
