One of my favorite hobbies is the Furry Fandom. In short Furry Fandom (furry for short) is a love of cartoon animals. If you've ever seen Disney's Robin Hood, that's the kind of stuff this fandom is based around. People who like cartoon animals call themselves "furries".
Furries are extremely diverse group and are extremely accepting of differences. You get all kinds of people from rednecks, hardcore christians, and flaming gays going to events together. Some furries are high school or college age kids trying to figure out their place in the world. Others have been in the fandom their entire lives. Me? I'm pretty new to this. I didn't realize I was a furry until my first convention Fur Reality in October 2013.
Most furries have a persona that they identify with. Mine is a mexican wolf named "Epoch". You can click the picture of him in the upper right to see the full reference sheet.
There's a few more things on my FurAffinity page but you'll need a FurAffinity account to see it.
Some furries like to dress up like animals in costumes called Fursuits. It can be a lot of fun. I find fursuits to be incredibly cute.
Here's a couple of videos of people preforming in fursuits.
