FurryMUCK

Furry is the largest and longest standing MUCK on the Internet to date (note MUCK, not overall MU*). With a database well over the 160,000 item mark, and a regular nightly showing of 325+ players, it's an active social environment. The theme is centered around the roleplay of Anthropomorphics (characters combining animal and human traits such as werewolves; also 'funny animals', toons, etc.) but all who play with respect are welcome.
