Cats quite often come and sit on people's lap whenever they get the occasion, anyway. And pretend they're sleeping. Though they're really just spying on us, you know?

They must always stand closer to the screen (or whatever it is we are doing) than we are.
I think some of my pet fish would react (suddenly moving in random directions) to stuff such as games on the TV, sometimes. Especially loud, low noises - it bothered them, I guess.
But I think animals in general (birds and mammals, at least) also tend to get quite excited when they hear the sound of an animal their species (or even sometimes when they see an animal looking like them, like a tiger, or a wolf, etc.) or a potential prey/predator, be it in a game or on TV.
