I'm sorry to hear that you're having this problem! I would be interested to know more about exactly what the cats are doing that concerns you, as true "aggressive" behavior or serious fighting would be unusual to see in a kitten this age. Normal play between two cats (including wrestling and biting) is often mistaken for fighting by owners, so I'm wondering if your cat may actually be playing normally with the younger kitten. If this is an aggression problem, this is quite serious at such a young age and would best be handled by a veterinary behaviorist - he/she can evaluate your cat to help determine what is causing the aggressive behavior, and put together a detailed treatment plan to work on the problem. This would likely include some methods to redirect her to some other activity if you see warning signs of an attack such as stalking, growling, etc. as well as possibly medication of some kind to help treat her aggression. Your veterinarian should be able to refer you to a behavior specialist in your area, if you ask.
