The Cat with the lovely big ears picture is courtesy of
" Buntekuh " from flickr.
Cats ears can pivot in 180 degrees, and also move up and down.
in each ear cats have 30 muscles (human have 6) and 12 or more are controlling the ear movement.
The cat use his ears as a radar. The ears can move in different directions and pinpoint the sound source without the movement of the cats head.
