You’ve probably heard it countless times: hay should be the majority of a rabbit’s diet. But have you ever stopped to wonder why? While those adorable bunny faces might beg for more pellets and veggies, it’s crucial to ensure they consume a significant amount of hay.

  • Dental Health: Rabbit teeth, much like human nails, grow continuously. Without rough foods like hay in their diet, their teeth can overgrow, leading to health issues. Processed rabbit food pellets aren’t abrasive enough to keep their teeth trimmed. Thus, hay becomes an indispensable part of their diet, ensuring their teeth remain healthy and at the right length. Overgrown teeth, or Malocclusions, can lead to infections and bacterial growth in a rabbit’s mouth. A diet rich in hay is the best preventive measure. 2
  • Natural Behaviors: Hay also allows rabbits to exhibit natural behaviors, ensuring their mental well-being. In the wild, rabbits are foragers. While they might not need these skills in the safety of your home, their instincts remain. Foraging for food in a pile of hay provides mental enrichment, ensuring they remain mentally healthy and content. Moreover, rabbits love to chew. Having ample hay to munch on can be comforting for them, especially when they’re stressed or anxious.

Types of Hay and Their Benefits

When it comes to feeding your rabbit, not all hays are created equal. Different hays offer varied nutritional values, and it’s essential to choose the right one for your furry friend.

Type of Hay Benefits
Timothy High in fiber and has rough strands ideal for digestion and dental health.
Orchard A grass-based hay that offers a variety of nutrients.
Oat Another grass-based hay that’s good for a rabbit’s teeth and digestion.
Meadow Packed with different grass types, offering a range of flavors and nutrients.
Herbal Contains a mix of hay with added herbs for extra flavor and nutrients.

While Timothy hay is often recommended for most rabbits, offering a mix can provide them with a broader range of nutrients and flavors. However, it’s essential to note that alfalfa hay, which is high in calcium and protein, isn’t ideal for adult rabbits. It’s more suited for younger rabbits, under six months, who require these nutrients for growth.

Tips for Feeding Hay to Rabbits

Ensuring your rabbit gets the best quality hay is crucial. While pet stores offer various hays, they might not always be the freshest. Consider sourcing hay from local farmers or specialized online stores that guarantee fresh, green hay. Remember, the greener the hay, the better!

  • Unlimited Supply: Always ensure your rabbit has an unlimited supply of hay. This doesn’t mean overfeeding but ensuring they never run out. Monitor their consumption to get an idea of their daily intake and adjust accordingly.
  • Variety: Offer a mix of different hays to provide a range of flavors and nutrients. This not only ensures they get all the essential nutrients but also keeps them interested.
  • Freshness: Always ensure the hay is fresh. Stale or damp hay can lead to health issues. Store in a cool, dry place and check regularly for mold or dampness.

Prevention of GI Stasis

Gastrointestinal Stasis (GI Stasis) is a severe condition in rabbits where their gut slows down or stops. In this state, rabbits can’t excrete, making eating uncomfortable. It’s incredibly dangerous and can be fatal if not treated promptly. Hay plays a pivotal role in preventing GI Stasis. The high fiber content in hay ensures their gut remains active. Processed rabbit food pellets, while convenient, don’t offer the same benefits as the natural strands of hay.

Dental Benefits of Hay

Rabbits have a unique dental structure. Their teeth, much like human nails, grow continuously. Without rough foods like hay, their teeth can overgrow, leading to health complications. Processed rabbit food pellets aren’t abrasive enough to keep their teeth in check. Thus, hay becomes an indispensable part of their diet, ensuring their teeth remain healthy and at the right length3.

Hay vs. Other Foods in Rabbit’s Diet

While hay is undeniably the most crucial part of a rabbit’s diet, how does it compare to other foods?

Food Type Benefits Drawbacks
Hay High in fiber, essential for dental and gut health, promotes natural behaviors. None.
Pellets Convenient, can be fortified with vitamins and minerals. Not abrasive enough for dental health, can be overfed leading to obesity.
Leafy Greens Provide variety and essential nutrients. Should be given in moderation.
Fruits Can be a treat, provides natural sugars and vitamins. High in sugar, should be given sparingly.

While pellets and veggies have their place, hay should be the primary food source, making up about 80% of their daily intake.

The Role of Hay in Young Rabbits’ Growth

Young rabbits, especially those under six months, have different nutritional needs. They’re rapidly growing and require a diet rich in protein and calcium. This is where alfalfa hay comes into play. Unlike Timothy or other grass-based hays, alfalfa is a legume hay, rich in calcium and protein. It’s perfect for young rabbits but should be replaced with grass-based hays as they mature.



Hay satisfies natural snacking and chewing urges, provides key nutritional components, and ensures a healthy gut and dental health.

Hay should comprise at least 75% of an adult rabbit’s diet.

Hay helps prevent digestive stasis, fur blockage, and calcium imbalance.

Young rabbits, especially those under six months, benefit from alfalfa hay, which is rich in calcium and protein.

Hay is abrasive and helps wear down continuously growing rabbit teeth, preventing overgrowth and related health issues.
