The ngii, also called the yao'yao after the sound it makes, is a semi-aquatic domestic animal indigenous to RyiX'yan (Hyoton III). A popular pet in the Xi'an Empire, it has lived alongside the Xi'an since they developed farming, and is used for pest control and fishing along with companionship. Ngii typically have free roam of the homes they live in, and sleep on perches meant to mimic low tree branches. Speakers of UEE Standard have been known to refer to the ngii as the yengi cat.
