For the plant species, see Cat's ear. Thirty-two individual muscles in each ear allow for a manner of directional hearing; a cat can move each ear independently of the other. Because of this mobility, a cat can move its body in one direction and point its ears in another direction. Most cats have straight ears pointing upward. Unlike dogs, flap-eared breeds are extremely rare (Scottish Folds are one such exceptional mutation).
Cats have excellent hearing and can hear sounds up to about 60,000 Hz while humans (with a few unusual exceptions) can only hear up to bout 20,000 Hz. This means cats can hear the ultrasonic noises made by rats and mice. In addition, they can pinpoint a sound source to within about 8 o thanks to their swivelling ears.
