The first thing to realize is that cats do not understand punishment. Encouraging good behavior with a reward is much more effective. There are two types of rewards — praise from you and a tasty treat such as a few kibbles of kitten food.
Keep training sessions short. Focus on one command at a time, and once mastered, move on to the next. Practice the commands in lots of different places around the house so that she gets used to responding to you in all sorts of situations. You can use the clicker technique to help with other aspects of your kitten's training, such as encouraging her to stand still for grooming and getting her used to traveling by car.
