FurryMUCK is one of the oldest and largest non-combat MUD-style games in existence. It was founded in 1990 as an online gathering place for furry fans to meet and socialize in a virtual role-playing environment. Over time, FurryMUCK has become one of the central focal points for furry fandom, with a user base consisting of several thousand, with over 150 users regularly signed on simultaneously.
Many furry fans state that their first exposure to furry fandom came from FurryMUCK.
West Corner of the Park is the central meeting place within the MUCK. It is held to a non-explicit rating and is generally continually populated. Visitors will emerge into the Park. There is also a webcomic of the same name which is set on FurryMUCK, usually in the park.
