Stereo hearing, what is that pray tell? The cat never takes it's eyes off the cup covering the bell, that's how it knows where it is. As for the pup, you're right, it isn't a fair test.

Stereo hearing - as in, both your ears work, so you can tell where sound is coming from. Most humans have it, indeed most animals. I, however, do not. You all take for granted your ability to pinpoint where noise is coming from. I am deaf on one side, so to me all sound comes from somewhere on my left side.

I didn't know you had a hearing loss. Now I see what you meant by stereo hearing.
