Hmm. I could suggest that you, er, try modifying your technique, Doug... ;-)

From what you say, so many things in daily life should be smelling of wee. Supermarket trolley handles, everything on the shelves (all put there by human hands), my steering wheel, the telly remote, my cat, my harmonicas, my oft-resorted to wine glass... Well, either (a) my sense of smell is too weak, or (b) there's no smell anyway, or (c) I don't do nearly enough sniffing around...
