Okay so I will be petting her and she will like lick my hand (which I know is normal), but then for no reason whatsoever, she will bite my hand. I don't know why, she just does it. Is there anything wrong? Or is she just trying to get my attention or something?

By the way... when she bites my hand, she doesn't bite hard enough to make it bleed, just enough to sting a little bit.
