I have a 7 week old kitten that I rescued when she was 3 weeks. Whenever I pet her she turns on her back and starts to bite and scratch, she'll pounce on my face if I hiss at her. She'll wake me up in the mornings by biting my cheeks, chin, and nose. She'll even be purring and biting/ scratching at the same time. They don't really hurt they're just annoying. I'm interpreting this as her trying to show affection? Can someone help me turn these 'love bites' into actual non dangerous affection?
