Eh. "Grossed out" isn't the term I'd use for my feelings. Then again, I've been known to dress outside the "societal norm" at times myself, albeit not to the extent of wearing what is essentially a sports mascot outfit in public.
Well, the idea was, it combined two things I like the most: women and cats.
Done correctly, it could be very erotic. Unfortunally, all the times I saw furries, it wasn't done that well and actually made me puke a little in a few instances.
It's probably the reason why I don't like looking at them lol.
