Hmmmm, cats generally rub their heads to scent mark their territory or as a sign of greeting (if you watch cats, when they walk up to each other, they either hiss and spit, ignore each other or rub heads).

My cat has a new one. Most of the time when you see it, it gives you that "I'm not hungry and your' not interesting" sort of look, but in the morning, it has taken to jumping into the car if I make the mistake (as I often do) of opening the car, and then having to go back to the front door to give the current Mrs GT a goodbye kiss.

So far, this has resulted in me getting up to 3 miles into my journey to work, before I have had to turn round cos I noticed a small furry shape sitting on the backseat, or have heard a yowl of discomfort as I took a turning too fast!
