Do cats have good hearing?
Yes. Cats have an extraordinary hearing range that is well beyond that of humans. A cat can hear sounds as low as 200 Hz (and so can hear a mouse moving through grass), and as high as 100 KHz (and so can easily hear the 20-50 KHz of rodent vocal sounds). Cats have mobile ear flaps or pinnae which help to collect sound and so improve hearing. They also help in determining the direction from which a sound is coming; but cats, like humans, do not excel in this regard.
