Well it's not even copyrighted at all because it is not really an idea to copyright it's more like a law . Just imagine copyrighting the idea of paying rent or needing a passport , though these laws were made by a group of people or one person , the government doesn't need to buy the copyright to use it .
Cats have been known for many things , purring , meowing , having 9 lives and ruling the internet but one of the most fascinating thing about cats is their ability to always land on their little tiny feet .
IT'S AMAZING RIGHT ???
This is possible because of a cat's 'righting reflex' , the ability to sense up from down . After it realises it's falling the cat rotates its body to make sure its feet are facing downwards . Cat's have an unusual flexible backbone and no collarbone that allows it the twist its body in any way possible , a flexible body and of course good natural instinct. That's the reason cats always land on their feet .
