Pigs

It's harvest season. We follow a litter of piglets from birth as they grow up in the Brecon Beacons. We test the theory that every piglet always returns to the same teat to suckle; show that pigs love mud to keep cool because they have practically no sweat glands and we show how intelligent they are with a series of puzzles. We also reveal that they are masters at the art of deception. Pigs tell porkies! Along the way we meet a pair of Kunekune pigs raised as domestic pets in the heart of London. We visit a farm that uses llamas to guard its sheep and meet a pet rabbit with a remarkable identity crisis.
