My kitty is generally very sweet, relaxed, and affectionate -- but a few times i have noticed that when I go to pet her, she'll put her teeth on my hand as if she is going to bite me! It doesnt actually hurt, it seems like it would be a play bite, except she is usually just relaxing and is not in a playful mode when she does this. Can i get her to stop doing this? I'm assuming its her way of saying "leave me alone" -- i dont mind letting her be, but i hate the behaviour -- how should i deal? thanks.
