Licked

I'm not sure what his deal is, but one of the cats has been regularly climbing up onto my shoulders and aggressively licking my head since we got back from Europe. The shoulder thing is fairly common, and he's done the licking thing in the past -- usually after I've gotten back from a run or if I've just washed my hair. It's the frequency and persistence that's so weird. It's kind of endearing, but it's also getting kind of annoying, especially since I'm beginning to get a little concerned that my head is going to start smelling like cat butt.
