Ferians are sentient beings that walk on four legs. They live in the world of furres, but beside furres, not with them. They live by a set of codes and laws all their own. Many Ferians hope some day to reach The Wylde, a place of safety and bounty. While most Ferians mean no harm, the acts of a few evil ones have led furres to a longstanding fear and distrust of their four-footed neighbours.
While "Ferian" is the term for sentient, non-anthropomorphic animals in Furcadia's official setting of the Dragonlands, the term "feral" pre-dates it and is still frequently used by players.
A rough distinction between the two terms may be that Ferians are sentient, i.e. have thoughts and feelings equivalent to humans/furres, whereas ferals have animal thoughts and instincts. This distinction, however, is hardly universal, and the interpretation will vary between individual dreams and players.
