My female cat is 2 years old. She is such a loving cat but sometimes when I'm petting her, she lashes out at me. Not always clawing me but sometimes she does. Like for instance, she was lying on me in my bed purring away but I could see she wasn't happy and next thing she will claw me then run away but will come back a bit later for more attention. Why does she do this. Is it just to tell me to stop.
