La Planète des chats

After the collapse of human civilization in Europe, rats swarm the ruins, more numerous and better organized than ever. Bastet, a supremely self-assured cat who can tap into the whole of human knowledge through a USB port grafted to her skull, leads a small, mismatched community — Champollion the translator parrot, her devoted human servant Nathalie, and Pythagore, the walking feline encyclopedia — on a desperate flight to New York, where the last Americans have barricaded themselves against the rising tide. The third novel in Bernard Werber's cat trilogy.
