If you have read The Magician's Nephew, you will know how Aslan created the land of Narnia first of all, and then the animals who were to live there. He made the earth bubble up into a collection of humps, large and small, which burst open to reveal all sorts of animals, insects, birds and reptiles. Many of the animals in the books, such as horses, bulls, pigs, lambs, cats, dogs and mice are farm animals, but they are not pets because in Narnia animals belong to no one.
Narnian animals are just as important as humans, and often much more clever and brave.
One of the bravest characters in The Chronicles is the mouse-knight, Reepicheep , who is willing to fight to the death for Aslan. Three of the most memorable animal characters are horses. Strawberry is the cab-horse who is changed by Aslan's magic into Fledge the flying horse in The Magician's Nephew , and then there are the two Talking Horses, Bree and Hwin, who help Shasta and Aravis escape the Calormen and ride across the Great Desert to safety. Think of Glimfeather the Owl in The Silver Chair, who helps Eustace and Jill in their quest to find Prince Rilian. And amongst the most loyal creatures who fight for Narnia in The Last Battle is Farsight the Eagle.
