AWWWW she's just being a kitty - some are passive, some are aggressive - I've never been bitten by any of my kitties. My daughter's Siamese is another story. Gibby will snuggle up to ya and purr and purr, and then out of the blue - BITE and hard. The tail becomes a wire brush and the fur stands up on his back. He's the only cat I've ever heard growl when the doorbell rings too.
