Most often, when cats bite they are trying to tell you that they aren't enjoying the contact that they are currently receiving. For felines, there is a very fine line between enjoyable handling and irritating petting, so while an owner may think a bite has come from nowhere, for a cat the action is entirely justified.

Why does my cat bite me when she's being affectionate?

Biting is generally something people associate with negative feelings, but cats are a little different. When your cat nibbles you playfully, she's really offering her affection. This is much different from a fearful or defensive bite that's meant to cause harm, and the feelings behind it are different as well.
