I learned watching Sesame Street that it takes all kinds of people to make the world go around. I also learned watching Sesame Street that sometimes, grownups dress up in animal costumes.
And sometimes grownups with a fetish for dressing in animal costumes all get together at conventions.
Really not sure what's going on in this photo, but some attendees apparently just wear tails. Dabblers in furriness, if you will.

Here's a rather foxy one.

Honestly, this is way weird, but it's just people in full-body costumes, some trying to look sexier than others. Not having seen furry photos before, I had imagined this scene as a little more strange, like, all different color bears dancing around.
