Here I am as a raccoon, dancing away in Luskwood.
I like my human avatar. (I take that back. I love my human avatar.) Excursions in fur, therefore, won't be common for me. It is fun, though, to see the world from a different point of view. (Not to mention the differences in others' behavior. A 4'5" busty raccoon doesn't receive the attention that a 7'2" busty, leggy redheaded human gets. Why would that be, I wonder?)
Actually, people with furry avatars have my respect just for the practical and logistical considerations. The tail uses the same component as some clothing, and it's another thing to have to keep track of and animate. Then there are the larger-than-human avatars, such as dragons—I imagine those have to be constructed from whole cloth.
