Rabbits can eat a variety of vegetables, including leafy greens like cabbage, kale, broccoli, parsley, and mint, as well as other vegetables like carrots, bell peppers, zucchini, cucumber, brussel sprouts, eggplant, and broccoli and cauliflower florets. Rabbits should have an adult-sized handful of safe, washed leafy green vegetables, herbs, and weeds daily, ideally 5-6 different types, and new types of greens should be introduced gradually in small amounts to avoid potential stomach upsets. Fruits can also be fed in small amounts, about 1 to 2 tablespoons of fruit per 5 pounds of body weight, once or twice a week. However, rabbits should not be fed potatoes, corn, beans, seeds, nuts, onions, or rhubarb, as these can cause digestive problems or blood abnormalities
