It may take time for Lilly to accept your other cat even though she is the smaller new cat. Some cats just don't do well together so if this behavior continues or gets worse I would recommend either talking to a veterinary behaviorist (if there is one in your area) or considering finding someone who can provide Lilly a great life as an only cat.
