Scratching

Scratching is a biological necessity for your cat. So you can't really punish her for clawing the furniture, unless you have provided her with an alternative like a scratching post. If your cat has already scratched something, cover it with plastic and she will likely turn to the post instead. When you catch your cat scratching furniture, try squirting her with a water pistol or squirt bottle and use a firm "no." When she scratches her scratching post, reward her with praise.
