I’ve noticed a tendency among Beijingers to lament the passing of clear difference in appearance between the sexes. The refrain is that “these days everything is so confused”. A couple years ago, the youth did not yet have this predilection toward androgyny. Blame certain popstars. Of course, a few decades ago, there wasn’t much trace of the feminine along the gray, Mao-suited, streets of Beijing.
A “cat-head” would likely be a crafty or stealthy person.
