It's not exclusive to humans, but it's used towards humans far more than to other cats. Examples of other use (outside of regular cat-to-cat 'conversations' which are very rare indeed) are between mother and kittens and when a cat is in distress (eg. stuck in a hole)... although you could argue that the latter is intended for humans, I suppose. But mostly it comes from the "Mum, I need something!" or "Mum, I want attention!" that kittens give their mother, and on occasion their mother will give to them (in a "Come here, you dumbass kid!" way). I guess it stems from cats viewing us as a parent.
