Are you sure it was the rabbit? I only ask because I have lots of rabbits, one stretches out and sleeps in garden but has never touched a tomato plant or tomato. Just because you have rabbits, does not mean that is what is doing it. Any chance you also have ground hogs or deer or other animals? I found this, that might be helpful:
