Height: Kars is a tall, well-built man.

Appearance: Long, dark, wavy hair, usually covered by a tight, dark headband (he removes it as a sign of respect or aggression). Three small, sharp horns protrude from his head, and he wears a small tiara with a single ornament embedded in it.

In Switzerland, Kars wears a hat and coat to be less conspicuous in public.
Kars can't and doesn't speak human language because he's a cat. He only has the habits and mannerisms of a cat, and he speaks only cat language.
