@chaseawaythedark: "Feral" is the term furries use for quadrupeds, i.e. "wild" animals. It's actually a bit of a misnomer, since in common usage, "feral" refers to domesticated species that have returned to the wild—anything that began wild wouldn't be feral.
It's akin to how anthropomorphism technically refers to any humanizing quality (eg. speech, intellect), but furries use "anthro" nigh-exclusively to mean humanoid physiology (in contrast to "ferals").
What's the difference between a feral and a furry?
