I Love My Cats, but I've Still Got Too Many People to See

I love my cats, but they're not particularly bright. They stare off into space. Their hearing and sense of smell is better than our dogs,. More of their brain is devoted to the sense of smell in particular. That's why they turn their head and then look - probably following the scent. The idea that they're seeing things, seeing things that we can't see, that are there in the room is that that's just an assertion. I don't know. Possibly.
