There is only one Hello Kitty, but there are other similar-looking bobcat characters in the Sanrio family, so it's easy to get confused. There's Mimmy White, who is Hello Kitty's twin sister. While Hello Kitty typically wears a red bow below her left ear, Mimmy White wears a yellow bow below her right ear. There's also Hello Kitty's boyfriend, Dear Daniel, who has hair on top of his head. Hello Kitty also has a grandma, grandpa, mom, and dad, as well as pet cats called Charmmy Kitty and Honeycute, who have more cat-like features.
