Bird watchers. Ha! I dislike most TV shows, but do enjoy nature documentaries. I'll sit there in the evening, too tired to do anything else, with the kitten snoozing on my lap. Wolf documentaries, hippos, horses, bears - the kitten just snoozes away as if it didn't exist. But a couple weeks ago there was a segment about a local birdwatching club and what they were looking at in the marshes. The kitten instantly popped up and ran over to the TV screen, leaping up and repeatedly swatting at it the whole time. So cats perceive too, and don't just see. Of course, some of those birds which looked small on the screen were actually large hawks which sometimes of eat kittens, instead of the other way around.
