Innovation i guess..!

I heard from my teacher that Deer can hear even the slightest sound. And at the same time Tiger can walk without making the slightest sound... isn't it cool. Just like creating a program and another program which can hack it. At nights small animals like rats, etc come out of their earth holes and roam around in search of food. The owl too. Its very difficult to catch the prey if it hears any sound. Isn't it? Thats why the feathers of owl are in such a way that it can move fast in air without making a slightest sound... and also another feature is its capable of rotating its head 360 Degrees.
