I found this on the web: "Rabbits love garden vegetables, especially leafy greens. Plants chewed off at ground level or cleanly sliced stems are marks of a rabbit. Rabbits have many predators including dogs, foxes, and snakes. Predator urine, human hair, and hot pepper spray can be used as deterrents. Rabbit fencing is another option: it should be 1.24 cm (1/2 inch) wire mesh at least 92 cm (3 feet) high and buried 46 cm (18”)."
Now, you'd want to think about what you use as a repellent around your edible garden!
