Only they know what they are thinking.

I've known dogs to be jealous of their reflections. But cats? Practically since the day I got him, when I've sat on my bed and petted my cat, he has preferred to sit in my lap facing the mirrored door on my closet. I always figured he liked to watch himself being petted. This morning suddenly he saw something in the mirror he hadn't noticed before. His eyes lit up. I think he knows that the cat in the mirror is him. But maybe he doesn't know that me in mirror is me? He slipped off my lap trotted over to the door and started scratching the mirror to get at or get the attention of something on the other side. In the few minutes since, he's begged for my attention several times.
