cheS — Klingon Dictionary

E-mail from Dr. Marc Okrand to naHQun July 4, 2016:

For "bunny"... There's a Klingon animal that's sort of like a rabbit called a cheS. So a rabbit on Earth would be, I guess, a tera' cheS, though, in context, cheS is good enough. And a "bunny," I supposed is a cheSHom or maybe cheSoy.
