Fan Casting Cassie in Animorphs

Cassie lives on a farm with her parents, both of whom are veterinarians. She is the most knowledgeable about animals, and she is also an environmentalist. She is best friends with Rachel, although their personalities and styles are polar opposites. She loves nature and animals; that is why Marco always calls her a "tree-hugger". Cassie is also an estreen, the Andalite term for someone who is naturally talented at morphing. Throughout the series, she develops a relationship with Jake.
