Read Warriors The new prophecy by Erin Hunter (the whole series). It is about feral cats going on a quest to the sundrown place (aka the beach) so the can save their clans ( groups of cats with names like Windclan or Thunderclan) from the destruction of their homes. I know it doesn’t sound very much like an adventure but they travel from the forest through cities, mountains, and other forests to reach the sundrown place. But if you want to really know the cats and clans start with the first series of Warriors (the original). These is one of my favorite books. You also might want to try: Savvy by Ingrid Law, Stuart Little by E.B. White (it’s for younger people but it’s still great), and and any Eva Ibbotson book.
