Rabbits have unique dietary requirements and it is important to provide them with a balanced and nutritious diet to ensure their health and well-being. The following are some guidelines for feeding rabbits:

1. Hay: Hay should make up the majority of a rabbit's diet. Timothy hay is a good choice, as it is high in fiber and low in calories. Other good choices include oat hay, orchard grass, and brome hay.

2. Fresh Vegetables: Fresh vegetables should also be a part of a rabbit's diet. Good choices include dark, leafy greens such as kale, spinach, and collard greens, as well as carrots, broccoli, and celery.

3. Pellets: Pellets can be fed in moderation and should be high in fiber and low in calories. Look for a good quality pellet that is specifically formulated for rabbits.

4. Water: Fresh, clean water should always be available to rabbits. A water bottle is the best way to provide water, as it keeps the water clean and prevents spills.

5. Treats: Treats should be given sparingly and in moderation. Good choices include small pieces of fruit such as apple or banana.

It is important to avoid feeding rabbits foods that are high in sugar, such as candy or chocolate, as well as foods that are high in fat or calories. Additionally, it is important to gradually introduce new foods to a rabbit's diet to avoid digestive issues. If you are unsure about what to feed your rabbit, consult with a veterinarian who is experienced in treating rabbits.
