There are a lot of books out there where animals play an important role. Sometimes, they are major characters that contribute to the story.
Think of The Chronicles of Narnia by C. S. Lewis. Aslan is a talking lion. Mr. And Mrs. Beaver help the children on their journey. These talking animals have human mindsets.
Why are stories like this one so popular? Why are we as readers drawn to animals that talk!?
Well for one...how cool would it be if they really could talk!
Most people have had a pet at some point in their life. The bond you develop with your pet is pretty special. If you could converse with them it would be super amazing!
Since talking with animals isn't possible, having them talk in books is the next best thing.
