Does your cat play too rough? Sometimes it can be difficult to distinguish between playfulness and aggression. What the cat is actually doing is engaging in a type of behavior that is a combination of both predatory play or sneak attack" and is an expression of a cat's instinctive hunting skills at work -- on you! While it can be flattering to know that you have been selected as a playmate. You are not alone if you are not particularly enjoying all the scratching and biting.
