Ritz doesn't pay much attention to TV but we have a sound file on one of the computers that makes a meow noise that makes her come running from anywhere in the house, followed by a worried look.

She also comes running if one of us is making sounds we don't normally make. I had a coughing fit one day, and was sitting in a chair in my upstairs office, she came charging up, jumped on the table and raised her face to mine (we call this act being "nosed" by the cat)....like "what's wrong mom?"

she does have a keen sense of anything that isn't the norm.
