Leek is an ingredient that works great in many dishes and will be a constant in your pantry. But can leek be a part of your furry baby’s pantry? 

Leek is a big no-no when it comes to the rabbit diet. Leek is one of the food items that are highly toxic for rabbits. Eating leeks can cause health problems in rabbits such as Hemolytic Anemia. 

It’s common knowledge that leek is highly nutritional but does that apply to rabbits as well? We will discuss this in this blog.

Let us hop straight in! 


Can I Feed Leek To My Rabbit?

Leeks belong to the Allium family, the same as garlic and onion. They are healthy and nutritional. They are available all year round. Yet, is it safe for rabbits?


No, you should never give leeks to your rabbits. It is one of the toxic foods for rabbits. Leeks are high in calcium and phosphorus and can cause stomach problems in rabbits. 

Rabbits are picky eaters. Since leeks belong to the onion family, they produce intense aromas which rabbits don’t find pleasant. Bunnies hate this aroma and will avoid leeks at any cost. 

While we may find it a healthy veggie, rich in vitamins A, C, and K, manganese, iron, as well as essential antioxidants like polyphenols and sulfur compounds, it is not safe for your furry friends.

Leeks are members of the Allium family and consist of organosulfur compounds which will convert into disulfides.

Disulfides are oxidizing agents known to damage red blood cells, resulting in hemolytic anemia. It can result in physical weakness, dizziness, dull eyes, fever, and more serious health problems in rabbits. 

Hemolytic anemia is a disorder in which red blood cells are destroyed faster than they are being made. The destruction of red blood cells is called hemolysis. Red blood cells carry oxygen to all parts of the body.

If you have a lower number of red blood cells than the normal amount, you have anemia. When you have anemia, your blood can’t bring enough oxygen to all your tissues and organs.

Even though leeks are high in nutritional value, their value comes to zero for rabbits. How good they are for humans, that is not the case for rabbits. For them, leeks are just toxic and there’s no nutritional gain from leeks for rabbits. 

Since they are difficult to digest, you should expect your furry friends to suffer from digestion issues as well as the production of gasses that they will not be able to expel.

Leeks will also weaken your rabbit’s immune system. A weak immune system is very dangerous in the case of rabbits as they can contract many diseases easily. 

If you are planting leeks in your garden then we recommend you fence it. Even though rabbits don’t like leeks and won’t eat them, you don’t want to experiment or risk your rabbit nibbling the end of this toxic plant.
