Can Rabbits Eat Mustard Greens

Mustard greens are leafy green vegetables that come from the mustard plant, which belongs to the Brassicaceae family. They have dark green, crinkly leaves with a peppery and slightly bitter taste. Various cuisines commonly use mustard greens for their unique flavor and nutritional value.

But can rabbits enjoy them too?

Yes, rabbits can enjoy mustard greens! Mustard greens can be a healthy and tasty treat for rabbits when offered in moderation. These greens are rich in vitamins and minerals, such as vitamin A, C, and K, which are essential for a rabbit’s overall health. 

But like every treat, too much mustard greens can lead to various health issues.

So, should you feed mustard green to your rabbits or not?

Let’s find out!

Can Rabbits Eat Mustard Greens?

Rabbits can indeed eat mustard greens, but there are a few things to keep in mind.

Mustard greens are safe and healthy for rabbits in small amounts. They can be a yummy treat for your bunny! But remember, bunnies have sensitive tummies, so it’s essential to introduce new foods slowly.

Imagine your rabbit’s tummy as a little delicate machine that needs the right fuel. If you suddenly give them a lot of mustard greens, it might upset their tummy and make them feel unwell. 

That’s why it’s better to start with just a tiny bit and see how they handle it. If they seem fine and happy, you can give them a little more later on.

Are Mustard Greens Healthy for Rabbits?

Yes, mustard greens can be a healthy addition to a rabbit’s diet when offered in moderation and as an occasional treat. 

A typical serving of mustard green (about 1 cup or 56 grams) contains:

  • Calories: 15 calories
  • Carbohydrates: 2 grams
  • Fiber: 1.6 grams
  • Protein: 1.5 grams
  • Fat: 0.2 grams

Other health benefits of mustard green may include:

Fiber Content

Like many leafy greens, mustard greens are a good source of dietary fiber. 

Fiber is crucial for a rabbit’s digestive health and helps keep their gut moving properly, preventing issues like constipation.


Mustard greens have a high water content, which can contribute to keeping rabbits hydrated, especially during hot weather.

Low-Calorie Treat

Mustard greens are relatively low in calories compared to some other treats, making them a better option for rabbits if given in moderation.

However, it’s important to note that while mustard greens can be healthy for rabbits, they should not replace the main components of their diet. 

Risks of Feeding Mustard Greens to Rabbits Too Often 

Feeding mustard greens to rabbits too often can pose some risks to their health. 

Here are the potential risks:

Digestive Upset

Rabbits have delicate digestive systems, and feeding them mustard greens too frequently can lead to digestive upset. 

These greens contain certain compounds that might not sit well with their sensitive tummies, causing issues like diarrhea or gas.

Calcium Content

Mustard greens contain calcium, and an excessive amount of calcium can be harmful to rabbits, especially adult rabbits. 

High calcium levels can lead to kidney problems and the formation of urinary stones.

Oxalic Acid

Mustard greens, like some other greens, contain oxalic acid. Consuming too much oxalic acid can interfere with calcium absorption and contribute to the formation of urinary stones in rabbits.

Risk of Obesity

Overfeeding treats, including mustard greens, can lead to obesity in rabbits. 

Rabbits should have a balanced diet that includes mainly hay, and treats like mustard greens should only be offered in small amounts.

Teeth Issues

Mustard greens are slightly high in oxalic acid, which, in large quantities, might negatively affect tooth health in rabbits. 

Proper dental health is essential for rabbits, and a balanced diet plays a vital role in maintaining healthy teeth.

Thus, it’s best to offer mustard greens as an occasional treat, not a daily meal. 

Moderation is key, and ensuring that your bunny’s diet is primarily based on high-quality hay, fresh water, and appropriate rabbit pellets will help them thrive. 

Can Rabbits Eat Both Raw and Cooked Mustard Greens?

Raw and Cooked Mustard Greens

Rabbits can eat both raw and cooked mustard greens, but there’s a slight difference between the two.

Raw Mustard Greens: 

Rabbits can eat raw mustard greens, and many bunnies enjoy munching on them! When the greens are raw, they retain all their natural nutrients, which is great for your bunny’s health. 

However, remember that mustard greens are like a treat for rabbits, so don’t give them too much at once. Just a small amount a couple of times a week is perfect.

Cooked Mustard Greens:

Cooked mustard greens are not recommended for rabbits. 

When you cook the greens, they can lose some of their essential nutrients and become a bit tough for your bunny’s tummy to digest properly. 

Raw is the way to go when it comes to mustard greens for rabbits.

So, rabbits can enjoy raw mustard greens as a tasty treat, but avoid giving them cooked greens to keep their tummies happy and healthy! 

Can Rabbits Eat Mustard Seeds?

No, it’s not safe for rabbits to eat mustard seeds. 

Here is why:

Mustard seeds are tiny and can be harmful to rabbits. 

These seeds are quite small and hard, and they could cause choking or get stuck in your rabbit’s throat or digestive system. 

That’s not good at all!

Also, mustard seeds contain some compounds that might not be suitable for rabbits. They could upset their delicate tummies and make them feel sick.

So, keeping mustard seeds far away from your bunny’s reach is best. 

How Often Should I Offer Mustard Greens to Rabbit?

Rabbits can have mustard greens as an occasional treat, not as their main meal. 

Remember, their primary food should be hay, which keeps their teeth and tummies healthy. Mustard greens are like a special dessert for them.

As a general guideline, you can offer mustard greens to your rabbit about 1 to 2 times per week. 

A small handful of fresh, washed, and chopped mustard greens is enough for one serving. 

This way, your bunny gets to enjoy the tasty greens without overloading their diet.

Can Baby Rabbits Eat Mustard Greens?

When it comes to baby rabbits, it’s essential to be extra careful with their diet.

Baby rabbits, also known as kits, have delicate tummies and special dietary needs. 

Mustard greens are not suitable for baby rabbits, and here’s why:

Baby rabbits should primarily rely on their mother’s milk for the first few weeks of their life. Mother’s milk provides all the essential nutrients and antibodies they need to grow healthy and strong. It’s crucial not to introduce any solid foods, including mustard greens until they are about 12 weeks old.

At around 12 weeks of age, you can start gradually introducing small amounts of fresh vegetables to your baby rabbit’s diet

However, mustard greens are not recommended as one of the first veggies to try. 

Instead, you can begin with gentle greens like lettuce, cilantro, or parsley.

Preparing Mustard Green For Rabbits

Preparing mustard greens for your rabbits is pretty simple! 

Here’s how you can do it:

  • Choose Fresh Mustard Greens: Pick fresh mustard greens from a trusted source. Make sure they are clean and free from any pesticides or chemicals that could be harmful to your rabbits.
  • Wash Thoroughly: Before giving the greens to your bunnies, wash them thoroughly under running water. This step removes any dirt, residues, or potential contaminants, ensuring the greens are safe to eat.
  • Chop chop chop: Rabbits have small mouths, so it’s best to chop the mustard greens into small, manageable pieces. This way, your bunnies can easily nibble on them without struggling.
  • Avoid Seasonings and Sauces: Never add any seasonings, dressings, or sauces to the mustard greens for your rabbits. Keep them in their natural, raw form to ensure they are safe and healthy for your furry friends.
  • Serve: Now it’s time to serve it to your little bunny. You can choose to serve it in their food bowl or directly to their eating place.

That’s it! By following these steps, you can prepare mustard greens for your rabbits in a way that is safe and enjoyable for them. 

Remember to keep treats in moderation, do not overdo it!

Can Rabbits Eat Other Types of Greens?

Yes, rabbits can eat various types of greens, and they can be a healthy and enjoyable addition to their diet! 

Here are some other types of greens that are safe for rabbits to eat:

  • Lettuce: Rabbits can eat various types of lettuce, such as romaine, green leaf, and red leaf lettuce. However, avoid feeding them iceberg lettuce, as it has lower nutritional value and can sometimes cause digestive issues.
  • Kale: Kale is a nutritious green that rabbits can enjoy in moderation. It’s best to offer it as an occasional treat due to its high calcium content.
  • Spinach: Spinach is safe for rabbits, but like kale, it’s high in oxalic acid and calcium. Feed it in moderation and as part of a varied diet.
  • Cilantro: Many rabbits love cilantro! It’s safe and can be given as a treat to add some extra flavor to their meals.
  • Parsley: Parsley is safe for rabbits and can be a tasty treat. Just like other greens, offer it in small amounts.
  • Basil: Rabbits can have basil, and it’s a fragrant herb that they might enjoy.
  • Dill: Dill is another herb that rabbits can eat in small quantities.
  • Arugula: Arugula can be given to rabbits occasionally, but not too much, as it’s a bit spicier than other greens.
  • Red Chard: This leafy green is safe for rabbits, but it’s also high in oxalic acid and should be fed in moderation.

Remember, while these greens are safe for rabbits to eat, you shouldn’t overdo them at any point. Variety is important for rabbits, so you can rotate the types of greens you offer to keep their diet interesting. 

Final Thoughts

To wrap this up, rabbits can eat mustard greens, but they should be given as an occasional treat.

Mustard greens can be a delicious and nutritious addition to your bunny’s menu, but it’s essential to offer them in moderation to avoid any potential digestive issues.

Remember, a rabbit’s main diet should consist of hay, fresh water, and rabbit pellets. Mustard greens, along with other vegetables, can be offered as treats to add variety and enrichment to their diet. 

If they seem to love the greens and don’t experience any tummy problems, it’s a good sign! However, if they show any signs of discomfort or loose stool, stop giving the greens and consult a veterinarian.
