Diet of Pet Rabbits: A Guide to Types of Hay

Timothy Hay

Timothy hay belongs to the grass family (Poaceae). Simply put, it grows much like rice, with multiple harvests possible throughout the year—typically up to three times. These are known as the first cut, second cut, and third cut. Among these, the first and second cuts are the most commonly found on the market.

Regardless of the harvest stage, the quality of the hay can vary depending on several external factors, such as its place of origin, local climate, and drying process. This means that even if two bags are labeled as "first cut," the texture, aroma, and appearance of the hay may differ. Therefore, it's important for rabbit owners to understand their rabbits' preferences to choose the most suitable hay and avoid waste.

Timothy hay is suitable for rabbits of all ages. During the juvenile stage (around 3 to 4 months old), it can be mixed with alfalfa hay for a balanced diet. Once the rabbit reaches adulthood (6 months or older), Timothy hay should become the main source of roughage, though it can still be blended with other types of hay to match your rabbit's taste.

Timothy Hay Feeding Guide for Rabbits

Timothy hay is one of the most important types of hay throughout a pet rabbit's life. As rabbits reach maturity and enter adulthood, they require a large amount of hay in their daily diet.

Hay not only helps wear down their continuously growing teeth to prevent overgrowth, but its high fiber content also promotes healthy digestion and supports intestinal function. It assists in passing ingested fur during grooming, helping to prevent dangerous hairball formation.

Additionally, Timothy hay is low in calcium and protein, which helps prevent urinary stones and reduces the risk of obesity. For devoted rabbit owners, understanding how to properly care for your furry companions' health and diet is essential. When you know how to nourish them well, your rabbits will thrive in both body and spirit.

Choosing the Right Timothy Hay for Your Rabbit

Because Timothy hay stays with a rabbit throughout its entire life and greatly affects its overall health, owners must pay careful attention to its quality and palatability. If your furry little companion stubbornly refuses to eat Timothy hay, it's worth spending some extra time comparing different brands or online sellers to find one your bunny truly enjoys.

Why Timothy Hay Matters

Timothy hay is not just a snack—it's a dietary essential. It provides necessary fiber that keeps a rabbit's digestive system functioning smoothly while helping to wear down their teeth naturally. A consistent supply of fresh hay maintains good gut health, reduces the chance of obesity, and keeps your rabbit happy and active.

Finding the Perfect Hay

  • Observe your rabbit's reaction: Try small portions from different suppliers to see which texture and scent your rabbit prefers.
  • Check for freshness: High-quality hay should look greenish, smell sweet, and feel crisp, not dusty or moldy.
  • Balance cost and quality: While premium brands can be pricey, investing in better hay can prevent costly vet visits later on.

With patience and care, you'll discover the Timothy hay that keeps your bunny healthy, satisfied, and full of life.

Timothy Hay Varieties: First Cut and Second Cut

Timothy hay is a staple in the diet of rabbits and other small animals. It is typically harvested several times during the growing season. The first cut and second cut vary in texture, color, aroma, and nutritional composition, making each suitable for different types of rabbits and feeding needs.

Appearance

First Cut: The first cut of timothy hay has thicker, coarser stems with fewer leaves. The flower heads are long and full, and the color appears light green to yellowish-green. It carries a mild grassy fragrance. As a rule of thumb, the thickness and abundance of stems can help distinguish between the first and second cuts.

Second Cut: The second cut features finer, longer stems with more leaves that feel softer to the touch. Its color is a deeper green and the scent is stronger. Similarly, checking the quantity and thickness of stems is a quick way to tell whether the hay is from the first or second cut.

Nutritional Composition

CutFiberProteinFat
First Cut±30%±11%±2.2%
Second Cut±20%±15%±3.6%

Feeding Recommendations

First Cut: First-cut timothy hay can be offered in unlimited amounts. Some rabbits may prefer eating the leaves and ignore the stems—sometimes even pulling them out to play. However, because the stems are high in fiber, they are an essential part of a rabbit's diet. For picky eaters, try trimming the stems shorter so your rabbit learns to treat them as food rather than toys.

Second Cut: Second-cut timothy hay can also be fed freely. Its soft, leafy texture makes it ideal for young rabbits, those transitioning between hays, or rabbits with dental issues. Most rabbits accept it readily. However, since it contains less fiber and more protein, it can lead to weight gain if not balanced properly with pellets and other food sources.

Orchard Grass: A Tasty Choice for Your Rabbit

Mr. and Mrs. Bunny always seem to have days when their appetites grow bigger. That 1-kilogram bag of timothy hay often ends up being pulled out and played with, eventually flattened into a bunny-made tatami mat. Half of it goes to waste, and as time goes on, your rabbits become pickier about hay — the brands they like get pricier while your wallet gets thinner, yet their tummies aren't necessarily happier.

If your rabbits have started acting this way, consider introducing Orchard Grass! This gentle and fragrant hay is suitable for rabbits of all ages. For young rabbits around 3 to 4 months old, you can mix it with a small amount of alfalfa hay. For rabbits of other ages, adjust the feeding amount according to their individual needs.

Orchard grass is not only nutritious but also provides excellent fiber support for digestion, making it a delightful addition to your bunny's daily diet.

Orchard Grass Feeding Guide for Rabbits

Compared to Timothy hay, orchard grass has a higher palatability and a milder aroma with a lightly sweet scent. This makes it especially effective for picky eaters who tend to lose interest in other hays.

Orchard grass is rich in fiber yet low in protein and calcium, making it a healthy dietary choice similar to a "natural supplement." Rabbits can enjoy it freely without worrying about overconsumption.

Hays that contain more leaves are ideal for rabbits who prefer softer textures and dislike coarse stalks. If your rabbit has grown tired of Timothy hay, switching to orchard grass is worth a try.

Alternatively, you can mix the two types of hay—2 parts orchard grass to 1 part Timothy hay— to encourage your rabbit to eat more consistently while providing variety in both taste and nutrition.

A balanced mix not only stimulates appetite but also promotes better digestive health in your furry friend.

Appearance of Orchard Grass

Scientific Overview: Orchard grass, often called "rabbit grass" in some regions, is a popular forage plant known for its rich green color and sweet, pleasant aroma. This grass is commonly cultivated for feeding small animals such as rabbits, guinea pigs, and other herbivores.

Appearance and Comparison: At first glance, orchard grass can be difficult to distinguish from timothy hay, especially when it's cut for the second harvest. However, compared to timothy, orchard grass tends to maintain a greener hue and carries a naturally sweet fragrance that many animals find appealing.

Usage and Benefits: Thanks to its soft texture and flavorful scent, orchard grass is an excellent choice for encouraging picky eaters to consume more fiber. It's often mixed with other hay varieties to create a balanced, aromatic diet for small pets.

Oat Hay

Just as its name suggests, oat hay is known for its naturally pleasant, slightly sweet flavor. It features coarse stems and relatively few leaves, which makes it a high-fiber forage that can support healthy digestion and gut function. The thicker stalks also help rabbits wear down their teeth effectively.

In the past, many people believed that eating too much oat hay could lead to obesity or cause bloating. Because of this, some online sources recommended against using it as a staple food. However, in 2010, a group of physicians offered a different perspective: nutritionally, oat hay does not contain more fat than other types of hay. They argued that it is unlikely to cause weight gain—in fact, it may even help with weight control.

The misunderstanding that oat hay contributes to obesity or bloating may stem from confusion between oat hay (the stems and leaves) and oats (the grains or flakes), which have very different nutritional properties.

Oat hay is especially suitable for adult rabbits, while young rabbits should primarily eat alfalfa hay. It has a mild, buttery fragrance that many rabbits find very appealing. You can offer it as a treat or mix it with other types of hay to encourage picky eaters to eat more fiber.

Oat Hay Feeding Recommendations

Oat hay are known for their excellent palatability and high acceptance among rabbits. They can be mixed with timothy hay to create a blended hay mix that encourages picky eaters to enjoy their meals. Oat hay can also be offered as a healthy treat.

Their high protein content makes them a great addition to alfalfa hay, attracting young rabbits that have just been weaned to eat more hay. The tender leaves are rich in fiber and easy to digest, enhancing flavor when combined with alfalfa. Oat hay also help prevent hairball formation, support digestion, and stimulate appetite—making them ideal for rabbits with poor appetite, as well as pregnant or nursing does.

Appearance of Oat Hay

Oat Hay is a type of grass forage commonly fed to rabbits. Its distinctive appearance includes thick, pale-yellow stems, which serve as the key identification points.

Compared to first-cut timothy hay, oat hay is usually broader in width and contains fewer leaves. The stems are abundant, offering a coarse texture that supports healthy chewing and dental wear in rabbits. Its aroma is mild and slightly sweet, making it an appetizing choice for many herbivores.

Because of its unique structure and nutritional balance, oat hay serves as an excellent addition to a varied hay diet, providing both fiber and enrichment for small animals.

Bermuda Grass

Fresh Bermuda grass may look like ordinary roadside weeds, but in fact, it's one of the most common types of turf grass you see in lawns and gardens. The difference lies mainly in how it is cultivated—grass grown for landscaping may use different pesticides or fertilizers compared to grass cultivated specifically for feeding animals.

For Rabbits: To Eat or Not to Eat?

Many rabbit owners worry when their rabbits refuse to eat hay or grass, as not eating enough fiber can cause serious digestive issues. However, what if your rabbit is more of a "sumo-sized" bunny, like the adorable "Bunnaihana" type? Too little fiber is a concern, but eating too much can also lead to obesity in rabbits.

Therefore, it's recommended to feed rabbits Bermuda grass gradually and in moderation. Bermuda grass hay is particularly suitable for adult rabbits. For young rabbits (around 3 to 4 months old), you can mix it with alfalfa hay to help them practice eating grass and transition smoothly into a balanced diet. For rabbits of other ages, the feeding ratio should be adjusted according to their individual health and appetite.

Bermuda Grass (Cynodon dactylon) — also known as Bermuda Grass Hay — is a healthy, fibrous choice for maintaining a rabbit's digestion and overall wellbeing.

Bermuda Grass Feeding Guide for Rabbits

Compared to other hay types, Bermuda grass has a slightly different nutritional profile. It is high in fiber and protein but low in fat and calories—making it an excellent choice for overweight rabbits. Because of this, it's often nicknamed "diet hay."

When to Use Bermuda Grass

Bermuda grass is softer and gentler than some other hay varieties, which makes it suitable for rabbits with oral health issues such as malocclusion, overgrown teeth, or mouth wounds. You can mix Bermuda grass with orchard grass to make the texture more appealing and easier to chew.

Feeding Challenges

The main drawback of Bermuda grass is its poor palatability. Like humans eating bland health food, rabbits may show little enthusiasm for it at first. However, with patience and gradual introduction, they can learn to accept it. Picky eaters, in particular, may need extra time to adjust.

Suitable for Young and Expecting Rabbits

Because of its fine stems and small leaves, Bermuda grass is also appropriate for young rabbits transitioning to hay. The small pieces help them practice chewing and get used to grass texture. For pregnant or nursing rabbits, it can be used in larger quantities as soft bedding. This provides a cozy, warm, and calming environment for both the mother and her kits.

Overall, Bermuda grass is a valuable addition to a rabbit's diet and care routine—especially for managing weight, supporting dental health, and providing comfort during special stages of life.

Appearance of Bermuda Grass

Scientific Description: Bermuda grass, known locally as "rabbit grass," is a common species that can easily be mistaken for roadside weeds. At first glance, it appears dry and unimpressive, with no particularly noticeable fragrance.

Key Identification Features: The plant is characterized by its sparse stems and an abundance of extremely fine leaves. This delicate leaf structure distinguishes it from other grass varieties.

Note: Bermuda grass thrives in warm climates and is widely used in lawns, gardens, and sports fields due to its resilience and fast growth.

Alfalfa Hay

Alfalfa hay is especially suitable for young rabbits (under three to four months old), postnatal rabbits, underweight rabbits, and rabbits recovering from illness that need extra strength.

Alfalfa, also known as Medicago sativa or lucerne, belongs to the legume family. The most commonly used type today is purple alfalfa. It is a type of forage grass that is high in calcium and protein but lower in fiber compared to other hays. Because of its rich nutritional profile, alfalfa is often considered the "king" of forage grasses.

Alfalfa hay is ideal for:

  • Young rabbits (under three to four months old): provides growth nourishment. After four months of age, it should be gradually reduced and mixed with other types of hay.
  • Postnatal mother rabbits: helps replenish nutrients until the kits are weaned.
  • Underweight rabbits: supports rabbits that have become thin due to environmental or human factors.
  • Rabbits recovering from serious illness: restores physical strength and energy.

During feeding, if you notice pigmented or calcium-rich urine (appearing orange-red, milky, or yellowish with white sediments when dry), it is recommended to pause feeding alfalfa hay. Consult with a veterinarian and observe your rabbit's overall behavior before reintroducing or mixing alfalfa with other hay types in moderation.

Feeding Advice for Alfalfa Hay

For adult rabbits (six months and older): Unless there are special circumstances, it's not recommended to feed only alfalfa hay as their sole source of forage. Alfalfa is not harmful, but it should be fed in moderation.

Because alfalfa is rich in nutrients, excessive consumption can lead to health issues such as calcium-rich urine or obesity in adult rabbits. During adulthood, it's best to mix alfalfa with other types of grass hay or alternate between them to maintain a balanced diet.

Providing too much alfalfa over time may cause serious urinary tract problems, such as bladder or kidney stones. Always ensure a variety of hay to keep your rabbit healthy and happy.

Alfalfa Grass: Appearance and Quality Comparison

Alfalfa grass, also known as "rabbit grass," varies in appearance and quality depending on its origin and processing method.

Most imported alfalfa grasses are processed through drying. As a result, they tend to have smaller, yellowish leaves that can become brittle and break into light green powder. In contrast, Taiwan-grown alfalfa undergoes a shorter production process, making it relatively fresher. High-quality domestic alfalfa typically appears lush and dark green, with abundant leaves, a pleasant aroma, and excellent palatability.

Note: Some products marketed as "Kenting pasture" or labeled as "produced in Kenting, Taiwan" may actually be made from imported alfalfa rather than locally grown varieties. Consumers are encouraged to confirm with sellers before purchasing to ensure they are getting genuine domestic products.
