What vegetables are not safe for rabbits to eat?

Rabbits are herbivores and have a unique digestive system that is designed to process plant matter. While many vegetables are safe and nutritious for rabbits, there are a few that can be harmful or even toxic to them. Here are some vegetables that rabbits should not eat:

1. Avocado: Avocados are toxic to rabbits and can cause respiratory problems, heart damage, and even death if ingested.

2. Raw Onions and Garlic: Onions and garlic contain compounds that can damage red blood cells and cause anemia in rabbits.

3. Potatoes and Tomato Leaves: The green parts of potatoes and tomato plants contain a substance called solanine, which is toxic to rabbits and can cause digestive upset, neurological problems, and even respiratory failure.

4. Rhubarb: Rhubarb contains high levels of oxalic acid, which can lead to kidney problems and other health issues in rabbits.

5. Grapes and Raisins: Grapes and raisins can be toxic to rabbits and may cause kidney failure.

6. Cabbage and Broccoli: These vegetables can cause gas and bloating in rabbits, leading to discomfort and digestive issues.

7. Uncooked Beans: Uncooked beans, such as kidney beans and soybeans, contain a compound called lectin, which can be harmful to rabbits and cause digestive upset.

8. Mushrooms: Some types of mushrooms are poisonous to rabbits and can cause severe health problems, including organ damage and death.

9. Iceberg Lettuce: Iceberg lettuce is low in nutrients and high in water content, which can cause diarrhea in rabbits.

It's important to carefully research and understand which vegetables are safe for rabbits before feeding them to ensure their health and well-being. Consulting with a veterinarian or a knowledgeable rabbit care specialist can also help you create a balanced and nutritious diet for your rabbit.
