A while back, we nominated Sid for Goth Pet Of The Week.
He didn't win.
Is Sid Gothic? Well, he's partly black, mopes around, has a pretty smart set o' fangs, and gets tragically wonky and morose while musing over the meaning of Poe's "Israfel" on occasion (we just box him about the ears ever so slightly, seems to work). We'd say he's pretty goshdarn Goth, wouldn't you? Go tell 'em Sid sent ya.
