Fantastic Mr Fox by Roald Dahl

Boggis is a fat chicken farmer who only eats boiled chickens smothered in fat. Bunce is a duck-and-goose farmer whose dinner gives him a beastly temper. Bean is a turkey-and-apple farmer who only drinks gallons of strong cider. Mr Fox is so clever that every evening he creeps down into the valley and helps himself to food from the farms.
