Mothball Lionheart is a pre-made playable cat residing in Appaloosa Plains, the world shipped with The Sims 3: Pets. He lives with his owner, Hetty, whom he dislikes, his mate, Pickles, his kitten, Maria, with whom he is best friends, and Hetty's other cat, Muffin, with whom he is enemies.
Mothball fulfills Pickles' every wish, but independently of who the leader cat is, he is still seen as the wisest and oldest cat in the family. However, he is not technically the oldest cat in the family, being 17 days away from becoming an elder, while his mate Pickles is 10. He has no skills at the start of the game.
He appears to be a male Calico cat. Calico cats are, in general, almost always female, and male cats only exist due to a genetic disorder.
