Hetty Lionheart is a pre-made playable elderly Sim that lives in Appaloosa Plains. She lives in a musty Victorian house with her four cats: Mothball, Muffin, Pickles and Maria. She tries to get away from everyone to focus on her cats. Her neighbors generally don't like her and no one dares to cross her yard afraid of what she might do. She is pejoratively called the "Old Kitty" and "The Crazy Cat Lady" because of her huge love of cats. Her way of dressing, facial features and surname also hint to her love of cats. She is also initially one of the few Sims in Appaloosa Plains other than the local NPCs, Dorothy Button and Mollie Bullock, to have the Evil trait.
Hetty is best friends forever with Muffin, best friends with Maria, friends with Pickles, and disliked by Mothball. Hetty has two distant friends, Tate and Esme Curley. She is then disliked with almost everyone in the town. She is enemies with Vera Blackburn, a dog lover.
Hetty has one skill point in Charisma and carries a book in her inventory.
She once had a career in Science career, but shortly retired after as a Test Subject (level one).
