This must be the reason as to why the cat is such a great hunter. They can see small animals moving, even if they change direction quickly and are able to catch them with their quick speed. Most kitties have at some point brought in a mouse, bird, lizard, and even possum just to show there mums and dads how quick they are. Although both mum and dads would prefer this not to happen.
