For some it's easy, they just figure out a fursona and that's that, for others like me, they might go through trial and error to find out which animal works for them. For me, I was originally a dragon, then a wolf, then an otter for awhile, then a raccoon and then I've been a rat since atleast 2009 so that's what's worked for me the best. I guess I identify with rats since they're urban survivors in a cruel world and I guess because of a slight physical and sexual thing too, but I kept gravitating towards rat even when I was some of the other species. Rat is what feels right for me. Squeak! :3
