Actually, even without mandatory uniforms, its still hard to spot another furry. Firstly, most of them dont necessarily walk around with a phipaw on their forehead. There are several girls at my school that wear tails, but most if not all of them just wear them because they are "cute." None if any are actually furries. I know of one furry guy at my school, but thats because he is so open about not only his furriness, but also his bisexuality. For the most part, I dont think any bullies go near him because he is unaffected by them and, to be honest, I think he makes them uncomfortable.
So, I dont think its that easy anyways to find a furry because tails are now becoming less of a furry thing, and more of a general fashion statement, like a necklace of sorts. And I know of noone who wheres a collar because our disciplinary guy told some girl it could be used as a weapon against her in the case of a fight. Really....? I found that stupid, but whatever, now no one wears a collar anymore....
