I've never liked the idea of using the word "feral" to describe anthropomorphic characters whose only human features are intelligence and capacity for speech. Why? "Feral" as a word implies a certain lack of intelligence and/or reason, and a deeply animalistic personality besides.
Fear not, for I have found an alternative term in the pages of the tabletop RPG system "Hc Svnt Dracones." That term is: "lateral."
