TBH I'm perfectly fine with people not knowing, it's not like I'll tell them and they wake up the next morning thinking 'oh yeah, she's a furry'.
However my friend plans to get me a collar for Christmas, and if anyone asks about it, I'll just say I like wearing it. I mean if it's socially acceptable for guys to sag their pants and for girls to show almost all of their cleavage, why can't I wear a collar or a tail?
