Many of the animals found in our world can also be found in Narnia. In addition, there are talking versions of most of these animals. When Aslan breathed upon the first animal pairs, some not only gained thought and speech, but changed in size as well. Smaller animals (rodents, birds and small mammals) are larger than their non-talking relatives and larger animals are slightly smaller. Talking beasts can be divided into three main categories: Avian, Mammal, and Reptile. There are no talking fish or insects.
