Kittenbus (こねこバ, Konekobasu) is a main character in Mei and the Kittenbus.
The Kittenbus looks like a cat with space inside its back for a child or small person to ride in. He has four legs and he has brown and orange fur with yellow eyes that can light up to help it see in the dark. He can travel anywhere in seconds and is adorable.
The Kittenbus can make itself invisible, move incredibly fast to create a whirlwind, and like other cat vehicles, it can fly.
