You could add a third category with Neither and add hyena again. Another one which is closely related but neither is the Mongoose. You could also add Meerkat and prairie dog as little joke answers too.
Great quiz! A little on the easier side--nothing wrong with that! Was just thinking maybe you could make a follow-up one that's more difficult using lesser known types and/or hybrids and breeds? Such as serval, liger, azawakh, etc.. Just a thought!
