Who is Jenny from Ghost Girl: The True Story of a Child in Peril and the Teacher Who Saved Her and what is their importance?

Jenny is the cat that Jadie finds in a box in her garage. Jadie has been taking this cat food and has been taking care of it. She is upset when she tells Torey that the cat has disappeared. Jadie believes that Miss Ellie has taken the cat. If so, she says that Miss Ellie will kill and eat the animal. Although Amber tells Torey that Jadie killed the cat, Jadie says it was the Dallas characters who killed Jenny. The cat was laying on Jadie stomach when they pulled the animal apart. Lindy later makes a connection between the cat skeleton that Jadie's father reconstructed and the skeleton of Jenny. It is never determined, however, if this skeleton actually belonged to Jenny.
