One of my cats, Elvis, pays attention to the TV once in a while. He likes to snuggle with me when I'm watching TV, and sometimes I catch him watching. His little ears will twitch, and he will look from one side of the screen to the other, following whatever action is happening on the screen. It's really quite funny! I ask him if he's enjoying the show, and he looks at me, then looks back at the TV, as if I have somehow disturbed his concentration.
