Ceiling fans & mirrors

When Bec first moved in, one of her cats was terrified of the ceiling fan for a solid month. She would emerge from the basement, glance at the fan and then flee in terror whether it was running or not. Now Quinn is fascinated by ceiling fans. Is there something they know that we don't? In my mind they don't match the watchability factor of fires, sunsets, the ocean or babies but maybe I'm missing something.

Quinn is also fascinated by mirrors. He'll stare at himself or other things in the mirror for sustained periods when he's placid. Interestingly though, when he's cranky seeing himself the mirror seems to set him off, almost as if to say "and on top of everything else look at this body I'm stuck in that I don't even know how to use yet".

The whole concept of mirrors and understanding 'self' fascinates me. Apparently only a few animals are able to grasp the concept of 'self' and yet we as humans seem to grasp it at a very early stage. At least it looks like Quinn does but maybe I'm reading too much into his reaction (and in that vein, how do they know that animals don't understand 'self'?). Assuming Quinn does get it, it's amazing it happens at such an early stage. Or maybe he sees the babies in all the mirrors as competition, who knows.
