Well, I was playing with them both on my bed, then I put out the light to go to sleep. They both started walking up to my pillow, as if they had agreed on it or something. I turned on the light because I was surprised. The reason I was surprised, is that I am used to them being timid about coming near my pillow; they always stay at the foot of the bed, sleeping on or near my legs. So Zoey ran back as if guilty, and Sheena just stared at me with big eyes. Then they started biting each other. So I put the light out again and they immediately started marching up to my pillow again. I dunno; just weird and not like their usual behavior.
