My kitten (9 months old) keeps attacking me. I'll be sitting doing something (was just sitting reading with her next to me) and she'll jump on me and bite my hands/wrists/arms. It's not playfulness, she is really angry and it's hard work to get her off me. Its just happened and I had to scruff her to get her teeth off my skin. My arm is pretty scratched and sore and she's drawn blood in a few places. I love her to bits, never play with her with my hands and don't pester her but I'm getting a bit scared of her because of this. What can I do?
