Litten is a quadruped, feline Pokémon covered with primarily black fur. There are two red stripes around each of its legs and two horizontal stripes with a vertical stripe across them on its forehead.

It has a short muzzle with a tiny, black nose. A tuft of fur sits at the end of its long tail. Litten's fur produces flammable oils.
