Can Rabbits Eat Rhubarb? A Comprehensive Guide

As a rabbit owner or someone considering getting a rabbit, it’s crucial to understand what foods are safe and healthy for your furry friend. One common question that arises is whether rabbits can eat rhubarb. In this article, we’ll dive deep into the topic, providing you with the expertise and knowledge you need to make informed decisions about your rabbit’s diet.

Understanding Rhubarb and Its Properties

Rhubarb (Rheum rhabarbarum) is a perennial vegetable known for its edible stalks and large, green leaves. The stalks are often used in pies, jams, and other desserts, while the leaves are generally considered inedible due to their high oxalic acid content.

Oxalic acid is a naturally occurring compound found in many plants, including rhubarb leaves. When consumed in large quantities, oxalic acid can cause health issues in both humans and animals, such as:

  • Digestive problems
  • Kidney damage
  • Calcium deficiency

Given the potential risks associated with oxalic acid, it’s essential to understand how this compound affects rabbits and their unique digestive systems.

The Dangers of Rhubarb for Rabbits

Rabbits should never eat rhubarb, including both the stalks and the leaves. While the stalks contain lower levels of oxalic acid compared to the leaves, they still pose a significant risk to your rabbit’s health.

Here are some of the dangers of feeding rhubarb to rabbits:

  1. Digestive Issues: Rhubarb can cause digestive distress in rabbits, leading to symptoms such as diarrhea, bloating, and loss of appetite.
  2. Kidney Damage: The high oxalic acid content in rhubarb can lead to the formation of calcium oxalate crystals in a rabbit’s kidneys, potentially causing kidney damage or failure.
  3. Calcium Deficiency: Oxalic acid binds to calcium, making it unavailable for absorption in the rabbit’s body. This can lead to a calcium deficiency, which may result in weakened bones and dental problems.
  4. Poisoning: In severe cases, consuming large amounts of rhubarb can lead to oxalic acid poisoning in rabbits, which can be life-threatening.

Leaves High No
Stalks Moderate No

Relevant Information: Safe Alternatives to Rhubarb

While rhubarb is off-limits for rabbits, there are plenty of safe and healthy alternatives that your bunny can enjoy. Here are some examples:

  1. Hay: The foundation of a rabbit’s diet should be unlimited access to fresh, high-quality grass hay, such as timothy, orchard, or meadow hay.
  2. Leafy Greens: Offer a variety of fresh, washed leafy greens daily, such as:
  3. Vegetables: In moderation, you can provide your rabbit with small amounts of safe vegetables, including:
  4. Fruits: Offer fruits sparingly as occasional treats, such as:

Remember to introduce new foods gradually and in small quantities to avoid digestive upset. Always monitor your rabbit’s reaction to new foods and consult with a veterinarian if you have any concerns.

Expertise: The Role of a Balanced Diet in Rabbit Health

Providing your rabbit with a balanced, species-appropriate diet is crucial for maintaining their overall health and well-being. A rabbit’s diet should consist primarily of hay, with a small amount of fresh leafy greens, vegetables, and limited fruit treats.

Here’s a general guideline for a balanced rabbit diet:

  • 80-90% high-quality grass hay
  • 5-10% fresh leafy greens
  • 0-5% vegetables
  • 0-5% fruits (as occasional treats)

In addition to a balanced diet, rabbits need access to clean, fresh water at all times. Regularly monitor your rabbit’s water intake and ensure that their water source is clean and free from debris.

Preventing and Addressing Digestive Issues

Rabbits have sensitive digestive systems, and any sudden changes in their diet can lead to digestive problems. To help prevent digestive issues:

  1. Introduce new foods gradually: When adding new foods to your rabbit’s diet, do so slowly over a week or two, allowing their digestive system to adapt.
  2. Avoid sudden dietary changes: Stick to a consistent diet and avoid making abrupt changes, as this can disrupt your rabbit’s gut flora and lead to digestive upset.
  3. Monitor your rabbit’s droppings: Keep an eye on your rabbit’s droppings for any changes in size, shape, or consistency. Abnormal droppings can indicate digestive problems that require veterinary attention.

If your rabbit experiences digestive issues, such as diarrhea or loss of appetite, consult with a veterinarian familiar with rabbit care. They can help diagnose the problem and recommend an appropriate course of treatment.

The Importance of Hay in a Rabbit’s Diet

Hay is the cornerstone of a healthy rabbit diet, and for good reason. Not only does it provide essential nutrients, but it also plays a crucial role in maintaining your rabbit’s digestive health and dental well-being.

Here are some key benefits of hay for rabbits:

  1. Fiber: Hay is high in fiber, which is essential for maintaining a healthy digestive system. The fiber in hay helps keep your rabbit’s gut moving, preventing digestive issues like gut stasis.
  2. Dental health: Rabbits’ teeth grow continuously throughout their lives. Chewing on hay helps wear down their teeth naturally, preventing overgrowth and dental problems.
  3. Nutritional content: Grass hay, such as timothy, orchard, or meadow hay, contains essential vitamins and minerals that contribute to your rabbit’s overall health.
  4. Mental stimulation: Foraging and chewing on hay provides mental stimulation for rabbits, helping to prevent boredom and associated behavioral issues.

Ensure that your rabbit always has access to fresh, high-quality grass hay. Replace old hay regularly and store hay properly to maintain its freshness and nutritional value.


In conclusion, rabbits should never eat rhubarb due to the high oxalic acid content in both the leaves and stalks. Consuming rhubarb can lead to digestive issues, kidney damage, calcium deficiency, and even poisoning in severe cases.

Instead, focus on providing your rabbit with a balanced diet consisting primarily of high-quality grass hay, along with a variety of safe leafy greens, vegetables, and limited fruit treats. By understanding your rabbit’s nutritional needs and avoiding potentially harmful foods like rhubarb, you can help ensure your furry friend lives a happy, healthy life.

Remember, if you have any concerns about your rabbit’s diet or health, always consult with a veterinarian experienced in rabbit care for expert advice and guidance.
