Since the early days my cat, which is about 3 years old, likes to play with me by gently scratching and biting my hand without really giving any damage, but recently she's become more aggressive and attacks with force, leaving multiple scratch marks and tries to bite "for real".
If I try to stop her she sees it as "prey trying to resist" and attacks even more aggressively, and if I ignore her and walk away, she'll run behind and try to catch my legs to continue the "hunt". Are there any ways to make her understand that what she's doing hurts and she should take the game less seriously?
