Is a cat shy?

It depends on what kind of cat you get and its viewpoints on things. I have 3 cats. Two are SUPER outgoing, happy, and are attention lovers. The other just kinda stays under the bed until it's night time. And if I don't have guests over he'll be out in the open because he pretty much only trusts me and no other human being hence people calling him 'shy'. It just depends how the cat grew up and his/her viewpoints on noises & objects.
