Can Rabbits Eat Hazelnuts? [Serving, Risks & More]

Can Rabbits Eat Hazelnuts

Hazelnuts are edible nuts that come from the hazel tree (Corylus avellana). They are also known as filberts. Hazelnuts have a hard shell or husk that encloses the kernel inside, which is the part we typically eat. These nuts are popular in various culinary uses, such as baking, desserts, chocolates, and snacks.

However, while hazelnuts are safe and nutritious for humans, they are not suitable for rabbits. Rabbits have delicate digestive systems that are designed to eat primarily hay and fresh vegetables. Foods that are high in fat, like hazelnuts, can be difficult for rabbits to digest and may lead to health issues such as obesity and gastrointestinal problems.

Let’s find out why hazelnuts are not suitable for rabbits and also find out some alternatives.

Can Rabbits Eat Hazelnuts?

No, rabbits should not eat hazelnuts. 

Hazelnuts are not suitable for rabbit consumption due to their nutritional content, which can be harmful to rabbits’ health. 

Hazelnuts contain a significant amount of phosphorus, calcium, and are acidic, making them unsuitable for a rabbit’s diet. 

The high phosphorus and calcium content can lead to an imbalance in a rabbit’s diet, potentially causing health issues. Additionally, the acidity in hazelnuts can upset a rabbit’s sensitive digestive system.

How Much Hazelnuts is Too Much For Rabbits?

If your rabbit eats just a tiny piece of hazelnut, it’s probably not a big problem. 

But if they eat a whole bunch of hazelnuts, it could be really bad for themYou see, hazelnuts have a lot of fat, which is like junk food for rabbits. 

Too much fat can make their tummy upset and cause them to feel sick.

Nutritional Benefits of Hazelnuts

Hazelnuts offer several nutritional benefits, especially for humans. 

But a small amount of hazelnut can also be beneficial to our little bunnies.

A typical serving of hazelnut (1-ounce) contains:

  • Calories: 176 kcal
  • Fat: 17 grams
  • Carbohydrates: 6 grams
  • Dietary Fiber: 3.5 grams
  • Sugars: 1.1 grams
  • Protein: 4.2 grams

Other health benefits of hazelnut may include:

Healthy Fats

Hazelnuts are rich in monounsaturated fats, which are considered heart-healthy fats. These fats can help reduce bad cholesterol levels (LDL cholesterol) and lower the risk of heart disease when consumed as part of a balanced diet.


Hazelnuts provide a decent amount of protein, making them a valuable plant-based protein source for vegetarians and vegans.

Dietary Fiber

Hazelnuts are a good source of dietary fiber, which aids in digestion and helps keep the digestive system healthy.


Hazelnuts are rich in antioxidants, including phenolic compounds, which can help protect cells from oxidative damage caused by free radicals.

It’s important to note that while hazelnuts offer many nutritional benefits, they are also calorie-dense. 

Therefore, moderation is key when you treat your pet with that!

Risks of Overfeeding hazelnuts to rabbits

While hazelnuts have several health benefits, overfeeding can be risky too. They are often called a high-fat snack, which is not suitable for rabbits.

So, before you treat your bunny with hazelnuts, keep these in mind:

Digestive Issues

Hazelnuts are high in fat, and rabbits have sensitive digestive systems that are not well-equipped to handle a high-fat diet. Overeating hazelnuts can lead to gastrointestinal problems, such as diarrhea, bloating, and gas.


The high-fat content in hazelnuts can contribute to weight gain in rabbits. Obesity in rabbits can lead to a range of health issues, including joint problems, reduced mobility, and a decreased lifespan.

Dental Problems

Rabbits need to chew on fibrous foods like hay and fresh vegetables to wear down their continuously growing teeth properly. Hazelnuts are not abrasive enough to help with this dental wear, and overconsumption of soft foods like nuts can lead to dental issues.

Phosphorus and Calcium ratio

Hazelnuts contain phosphorus and calcium, but the ratio is not suitable for rabbits. An improper balance of these minerals can affect the rabbit’s bone and teeth health.

Potential Choking Hazard

Hazelnuts are hard and small, and if rabbits eat them too quickly without proper chewing, there’s a risk of choking.

Thus, you should aim for a healthy and safe diet that mainly consists of hay, along with fresh vegetables and a small amount of commercial rabbit pellets. 

Treats like hazelnuts should only be given occasionally and in very small quantities. 

Can Rabbits Eat Roasted Hazelnuts?

No, rabbits should not eat roasted hazelnuts, either. 

Roasted hazelnuts are not suitable for rabbits for the same reasons as raw hazelnuts. 

Can Rabbits Eat Roasted Hazelnuts

They are high in fat, which can be hard for rabbits to digest and may lead to obesity and digestive issues. 

The roasting process does not change the fact that hazelnuts are not a natural part of a rabbit’s diet.

Additionally, roasted hazelnuts may contain added oils, salt, or other seasonings, which are harmful to rabbits. These additives can cause health problems and upset the delicate balance of a rabbit’s digestive system.

So, roasted hazelnut is a no-no for rabbits.

Can Rabbits Eat Hazelnut Leaves?

The good news is that rabbits can eat hazelnut leaves, and it’s safe for them to do so. 

Hazelnut leaves are a type of green plant, and many rabbits love munching on different types of greens.

Just like how we humans enjoy eating yummy vegetables like lettuce and spinach, rabbits enjoy eating their greens too! 

Hazelnut leaves are like a special treat for them.

However, even though rabbits can eat hazelnut leaves, it’s essential to make sure they get a varied diet. They need other foods like hay and some rabbit pellets to stay healthy. Hazelnut leaves should be given as a treat and not as their main meal.

Also, remember to collect the leaves from places where there are no pesticides or chemicals sprayed on them. 

Make sure the leaves are clean and safe for our furry friends.

Nuts That You Should Avoid Feeding Your Rabbits

There are several types of nuts that rabbits should not eat because they can be harmful to their health. 

Here are some nuts to avoid giving to rabbits:

  • Almonds: Almonds are high in fat, which can be difficult for rabbits to digest. They can also cause obesity and other digestive problems.
  • Walnuts: Walnuts are also high in fat and can lead to similar digestive issues for rabbits.
  • Pecans: Pecans contain a high amount of fat and can be tough on a rabbit’s sensitive digestive system.
  • Macadamia Nuts: Macadamia nuts are known to be toxic to dogs, and while there is limited information about their effects on rabbits, it’s best to err on the side of caution and avoid giving them to rabbits.
  • Chestnuts: Chestnuts are starchy and can cause digestive upset for rabbits.
  • Pistachios: Pistachios have a higher fat content and can be harmful to rabbits if consumed in large quantities.

The main reason these nuts are not suitable for rabbits is that their digestive systems are designed to handle a diet of mostly hay and fresh vegetables. 

But nuts are high in fat and can lead to obesity and digestive issues in rabbits. 

Additionally, some nuts may contain substances that can be toxic to rabbits or cause other health problems.

Alternatives Treat Options for Rabbits

There are several safe and healthy treat options you can offer to your rabbit as alternatives to nuts or other unhealthy snacks.

 Treats are a great way to bond with your bunny and add some variety to their diet. 

Here are some excellent treat options for rabbits:

Fresh Vegetables

Rabbits love fresh vegetables! You can offer treats like small pieces of carrots, bell peppers, broccoli, celery, and leafy greens such as spinach, kale, and parsley. Just remember to introduce new vegetables gradually to avoid upsetting their sensitive stomachs.


Some fruits can be given as treats, but they should be offered in moderation due to their sugar content. Good options include small slices of apple, banana, blueberries, strawberries, and papaya. Remove any seeds or pits before giving them to your bunny.

Hay Cubes or Pellets

Hay cubes or special hay-based treats can be a healthy option for rabbits. They help promote dental health and provide some entertainment for your furry friend.

Dried Herbs

Rabbits enjoy the taste and smell of dried herbs like chamomile, mint, and dandelion leaves. These can be given as occasional treats.

Commercial Rabbit Treats

There are commercial rabbit treats available at pet stores. 

Look for treats that are specifically made for rabbits and have natural ingredients.

Offering a variety of safe and healthy treats will keep your rabbit happy and provide them with some extra joy in their day! 

Final Thoughts

To wrap this up, rabbits should not eat hazelnuts, whether they are raw or roasted. Hazelnuts are high in fat, which can be difficult for rabbits to digest and may lead to obesity and digestive issues. 

Additionally, hazelnuts contain phosphorus and calcium in an imbalanced ratio for rabbits, which can negatively affect their bone and teeth health.

Feeding hazelnuts to rabbits is not recommended as it can pose significant health risks. While hazelnut leaves are safe for rabbits and can be given as an occasional treat, the nuts themselves should be avoided entirely.

A proper and balanced diet for rabbits consists mainly of hay, fresh vegetables, and a small amount of commercial rabbit pellets.
