My daughter has a wierd little cat that is about 12 years old. She(the cat, not my daughter)tends to circle when she's hungry. She squalls and rubs against legs a lot, but in between she paces in a circle. The circle is about three feet in diameter and she always circles counter clockwise.* If I ever learn to speak cat, I'm going to ask her why.

*European version: The circle is about one meter in diameter and she always circles anti-clockwise.
