What's your favorite thing about furry? It could be about the fandom, the community, or just the topic itself.
For me, my favorite part would have to be that it's a creative rather than derivative fandom. Furry isn't a fandom based around a single work, or even a specific genre or fashion, instead it's based on a preference or affinity for anthropomorphic characters. There are few real set rules and no single agreed-upon universe or canon, which kind of gives any random grouping of fursonas and furry characters the appearance of an alien council. A lot of the fans are contributors to the material available, it's very self-sustained. For somebody like me, who enjoys creating original stories and universes, it's a great environment. I'm not limited to a specific canon, so as long as it's consistent with itself, anything I want to make is possible.
