The K'taris were a species native to either the Alpha or Beta Quadrants. They were covered in soft brown fur that made them look like a child's toy with neat little claws. When uneasy, their fur ruffled up, and when settled down they shiver to get it all back in place.
Ensign N'Kriil was a K'taris who served on board the USS Alliance in the 24th century. (TOS - Vulcan's Soul novel: Exiles)
