Timothy Hay for Rabbits: Selection, Storage, and Feeding Strategies

Timothy hay (Phleum pratense) is a grass hay widely recommended as the foundation of an adult rabbit's diet. This article provides practical guidance for rabbit owners, veterinary students, veterinary technicians, and veterinary professionals on selecting high-quality timothy hay, storing it to preserve nutritional value, and incorporating it into a daily feeding plan that supports dental and digestive health. The guidance focuses on management decisions you can make and observe at home or in a clinical setting, with clear criteria for when to escalate concerns to a veterinarian.

At a Glance: Timothy Hay Compared to Other Fiber Sources

Rabbits require a high-fiber diet to maintain gastrointestinal motility and dental health. The table below compares timothy hay with other common forage options to help you make an informed selection based on your rabbit's age, health status, and nutritional needs.

Research on fiber sources in rabbit diets confirms that forage type influences growth and feed conversion. A study evaluating the replacement of barley and dehydrated alfalfa with Sulla hay and common reed leaves in fattening rabbits found that growth rates remained similar across diets while feed conversion was higher in the alternative fiber group, confirming that different fiber sources can be valuable in pelleted feeds for fattening rabbits (Replacement of barley grains and dehydrated alfalfa by Sulla Hay and common reed leaves in fattening rabbits diet). Similarly, research on wheat straw and alfalfa hay as fiber sources for fattening rabbits in Algeria provides comparative data on how different fiber sources affect production outcomes (Value of wheat straw and alfalfa hay as fiber source for fattening rabbits in Algeria).

Why Timothy Hay Is the Recommended Staple for Adult Rabbits

Fiber Requirements and Digestive Physiology

Rabbits are hindgut fermenters with a specialized digestive system that requires continuous fiber intake. The cecum houses a microbial population that ferments fiber into volatile fatty acids, which serve as an energy source. Fiber also stimulates normal gastrointestinal motility, preventing stasis, a potentially fatal condition where the digestive tract slows or stops.

Timothy hay provides the structural fiber that rabbit digestive physiology requires. Studies comparing fiber digestion across species have examined how rabbits process timothy hay fiber relative to ruminants and equines, providing insight into the species-specific digestive adaptations that make grass hay a suitable staple for rabbits (Comparative digestion of timothy fibre by ruminants, equines and rabbits). Additional research on liquid and solid digesta retention in rabbits given timothy hay has characterized how feed moves through the rabbit digestive tract, reinforcing the importance of consistent fiber intake for normal digesta passage (The measurement of liquid and solid digesta retention in ruminants, equines and rabbits given timothy hay).

Dental Health and Continuous Tooth Growth

Rabbit teeth grow continuously throughout life. The incisors grow approximately 10 to 12 centimeters per year, and the cheek teeth grow at a slower but continuous rate. Without adequate wear from abrasive plant material, teeth can overgrow, develop sharp points, and cause painful ulcers on the cheeks and tongue. The silica content in grass hays like timothy provides the abrasive action needed to wear teeth naturally.

Timothy hay's stemmy texture requires more chewing than pelleted feeds or soft vegetables. This chewing action wears teeth and promotes saliva production, which helps buffer stomach acid. Rabbits that do not receive adequate hay are at higher risk for dental disease, which can require repeated veterinary procedures such as tooth trimming or extraction under anesthesia.

Comparison with Legume Hays

Alfalfa hay is a legume hay that differs significantly from timothy hay in nutrient composition. Alfalfa contains higher protein and calcium levels, which can be problematic for adult rabbits. Excess calcium is excreted through the kidneys, and high-calcium diets can contribute to the formation of urinary sludge or bladder stones in susceptible rabbits. The comparative nutritional profiles of alfalfa and timothy hay have been studied in other herbivores, including dairy cows, where the tradeoffs between these forage types are well documented (Alfalfa Hay Vs. Timothy Hay, and Alfalfa Hay Vs. Bran, for Dairy Cows).

For adult rabbits, timothy hay is generally preferred over alfalfa because it provides adequate fiber with lower protein and calcium. Alfalfa may be appropriate for young rabbits under six months of age, pregnant or nursing does, and underweight rabbits that need additional calories and protein. Transition from alfalfa to timothy should occur gradually as rabbits reach adulthood to avoid digestive upset.

Selecting High-Quality Timothy Hay

Visual Inspection Criteria

When selecting timothy hay, visual inspection provides immediate information about quality. High-quality timothy hay should have a green color ranging from bright green to olive green. The green color indicates that the hay was cut at an appropriate growth stage and cured properly. Hay that appears yellow, brown, or bleached may have been harvested late, exposed to excessive rain, or stored improperly.

The hay should contain a mix of stems, leaves, and seed heads. Stems provide the abrasive fiber needed for dental wear, while leaves contain most of the nutrients. A good balance of both components indicates that the hay was cut at the proper maturity stage. Hay that is predominantly stems with few leaves may be overly mature and lower in nutritional value, while hay that is mostly leaves may not provide adequate dental wear.

Smell and Texture Assessment

Fresh, properly cured timothy hay has a sweet, grassy aroma. A musty or sour smell indicates that the hay was baled with excess moisture or stored in damp conditions, which can promote mold growth. Moldy hay should never be fed to rabbits, as mold spores can cause respiratory irritation and gastrointestinal illness.

The texture of the hay should be dry and crisp, not damp or limp. Hay that feels damp at the time of purchase may have been baled too wet and could develop mold during storage. Hay that is excessively dusty may have been harvested in dry conditions or stored for an extended period. Dust can irritate the rabbit's respiratory tract, particularly in rabbits with underlying respiratory conditions.

Sourcing Considerations

Timothy hay is available from several sources, including pet supply stores, farm supply stores, online retailers, and directly from farms. Each source has advantages and limitations. Pet supply stores offer convenience but may have lower turnover, increasing the risk of purchasing older hay. Online retailers often provide a wider selection and the ability to purchase in bulk, but shipping costs can be significant. Buying directly from a farm allows you to inspect the hay before purchase and often provides the best value, but requires storage space and may not be feasible for owners with a single rabbit.

When sourcing hay, consider the harvest season. Timothy hay is typically harvested in late spring to early summer, with some regions producing a second cutting in late summer. First cutting hay tends to be stemmier and higher in fiber, while second cutting hay is often leafier and softer. Both can be appropriate for rabbits, though some rabbits show a preference for one cutting over another.

Organic and Conventional Options

Both organic and conventionally grown timothy hay are available. Organic hay is grown without synthetic pesticides or fertilizers, which may be a consideration for owners who prefer to minimize chemical exposure. However, organic certification does not guarantee superior nutritional quality. The nutrient content of hay is primarily determined by soil fertility, plant maturity at harvest, and curing conditions. Research on timothy hay grown on heavily fertilized soils has examined how soil fertility affects growth outcomes in animals fed that hay, indicating that soil conditions influence hay quality (Growth studies with calves and rabbits fed timothy hay grown on heavily fertilized soils). Additional research has explored amino acid biosynthesis in timothy hay grown with trace elements, further demonstrating that growing conditions affect the nutritional composition of the hay (Biosynthesis of amino acids according to soil fertility - IV. Timothy hay grown with trace elements).

Proper Storage to Maintain Nutritional Value

Storage Environment Requirements

Timothy hay should be stored in a cool, dry, well-ventilated area. Heat and humidity accelerate the degradation of vitamins and can promote mold growth. The ideal storage temperature is below 70 degrees Fahrenheit, and the relative humidity should be below 50 percent. Hay stored in a garage, shed, or basement should be protected from direct sunlight, which can degrade fat-soluble vitamins.

The storage area should be free of pests, including rodents and insects, which can contaminate hay and introduce disease risks. Hay should be stored off the floor on pallets or shelves to allow air circulation and prevent moisture wicking from concrete floors. A gap of at least six inches between the hay and the floor is recommended.

Container Selection

The type of container used for hay storage depends on the quantity and the storage location. For small quantities, a cardboard box with ventilation holes or a paper bag can work for short-term storage. For larger quantities, a plastic storage bin with a loose-fitting lid or a dedicated hay chest provides better protection from moisture and pests.

Avoid storing hay in airtight containers, as trapped moisture can condense and promote mold growth. The container should allow some air circulation while protecting the hay from direct exposure to humidity. If using a plastic bin, drill small ventilation holes in the sides to allow air exchange.

Shelf Life and Rotation

Timothy hay does not have a fixed expiration date, but its nutritional quality declines over time. Vitamin content, particularly vitamin A, degrades gradually during storage. Hay that is more than one year old may have significantly reduced vitamin content, though the fiber content remains relatively stable.

Implement a first-in, first-out rotation system. When purchasing new hay, place it behind or beneath older hay so that the older hay is used first. Write the purchase date on each container or bale to track age. For most rabbit owners, purchasing hay in quantities that will be used within three to six months provides a good balance between cost savings and nutritional quality.

Signs of Hay Deterioration

Inspect stored hay regularly for signs of deterioration. Discard hay that shows any of the following signs:

• Visible mold, which appears as white, gray, green, or black patches
• A musty, sour, or fermented odor
• Dampness or clumping
• Evidence of pest infestation, including droppings, webs, or chewed areas
• Excessive dust that remains after shaking the hay
• Discoloration, particularly yellowing or browning

Feeding deteriorated hay can cause gastrointestinal upset, respiratory irritation, and reduced nutrient intake. When in doubt, discard the hay and purchase fresh supplies.

Feeding Strategies for Optimal Health

Daily Feeding Amounts

Adult rabbits should have unlimited access to timothy hay at all times. The general guideline is that hay should make up approximately 80 percent of a rabbit's daily diet. A rabbit will typically consume an amount of hay roughly equal to the size of its body each day, though individual intake varies based on size, activity level, and metabolic rate.

To determine whether your rabbit is eating adequate hay, monitor the amount consumed daily. A rabbit that is eating well will produce a consistent volume of fecal pellets. A decrease in hay consumption accompanied by a decrease in fecal output warrants attention and possible veterinary consultation.

Feeding Methods and Presentation

How hay is presented can significantly affect consumption. Rabbits are natural foragers and prefer to pull hay from a rack or container instead of eat it from a bowl on the ground. Hay racks, hay balls, and cardboard tubes stuffed with hay encourage natural foraging behavior and reduce waste.

Place hay in multiple locations within the rabbit's enclosure to encourage movement and exploration. A hay rack attached to the side of the enclosure at head height, a hay ball on the floor, and a small pile in a litter box can all stimulate foraging. Rabbits often eat hay while using the litter box, so placing hay near or in the litter box can increase consumption.

Incorporating Timothy Hay into the Diet

Timothy hay should be the primary component of an adult rabbit's diet, supplemented with a measured amount of high-quality pellets and a small portion of fresh vegetables. The typical adult rabbit diet consists of:

• Unlimited timothy hay or other grass hay
• A measured portion of pellets, approximately 1/8 to 1/4 cup per 5 pounds of body weight daily
• A small portion of fresh vegetables, approximately 1 to 2 cups per 5 pounds of body weight daily
• Fresh water available at all times

Pellets should be plain, high-fiber pellets without seeds, nuts, or colorful pieces. The pellet portion should be limited to prevent obesity and encourage hay consumption. Rabbits that fill up on pellets may not eat enough hay, increasing their risk for dental and digestive problems.

Transitioning Between Hay Types or Cuts

If you need to switch your rabbit from one type of hay to another, or from one cutting of timothy to another, make the transition gradually over seven to ten days. Mix the new hay with the old hay in increasing proportions, starting with approximately 25 percent new hay and gradually increasing to 100 percent. Sudden changes in forage type can disrupt the cecal microbial population and cause digestive upset.

Some rabbits are particular about hay texture and may initially refuse a new batch of hay. If your rabbit refuses new hay, try mixing it with the old hay, offering it in a different feeder, or crumbling a small amount of a favorite treat over the hay to encourage sampling. Most rabbits will accept new hay within a few days.

Nutritional Considerations and Supplementation

Protein and Amino Acid Content

Timothy hay provides moderate levels of protein, typically ranging from 7 to 11 percent depending on maturity at harvest and growing conditions. This protein level is appropriate for adult rabbits, which have lower protein requirements than growing, pregnant, or lactating animals.

Research on nitrogen utilization in rabbits fed timothy hay has examined how fermentable carbohydrates affect protein metabolism. A study investigating the effect of d-mannitol on nitrogen utilization in growing rabbits fed a timothy hay diet found that the fermentable sugar increased the transfer of blood urea nitrogen to the cecum, where it was used for bacterial protein synthesis. Rabbits fed the mannitol diet showed increased cecal bacterial nitrogen and short-chain fatty acid production, along with decreased urinary nitrogen excretion, indicating improved nitrogen utilization (Transfer of blood urea nitrogen to cecal microbial nitrogen is increased by mannitol feeding in growing rabbits fed timothy hay diet). This research highlights the complex relationship between fiber fermentation and protein metabolism in rabbits.

Fiber and Digestibility

The fiber content of timothy hay is a key reason it is recommended for rabbits. Timothy hay contains both insoluble fiber, which promotes gut motility, and soluble fiber, which is fermented in the cecum. The balance of these fiber types supports healthy digestion and the production of cecotropes, the nutrient-rich feces that rabbits re-ingest to extract additional nutrition.

Research comparing fiber digestion across species has characterized how rabbits digest timothy hay fiber relative to other herbivores. Rabbits have a shorter digestive tract than ruminants and rely more on cecal fermentation, making the fiber quality of their forage particularly important (Comparative digestion of timothy fibre by ruminants, equines and rabbits). The retention time of digesta in rabbits given timothy hay has also been studied, providing insight into how fiber moves through the digestive system (The measurement of liquid and solid digesta retention in ruminants, equines and rabbits given timothy hay).

When Supplementation May Be Needed

Timothy hay alone does not provide complete nutrition for all life stages. Growing rabbits, pregnant or nursing does, and underweight rabbits may require additional calories and protein. In these cases, alfalfa hay or a higher-protein pellet may be added to the diet temporarily.

Rabbits with specific health conditions may require dietary adjustments. For example, a rabbit with dental disease that cannot chew long-stem hay may need hay that has been chopped or softened, or may require a temporary diet of softened pellets and critical care formula. These situations should be managed with veterinary guidance.

Practical Implementation: A Step-by-Step Feeding Plan

Step 1: Assess Your Rabbit's Current Diet

Before making changes, document your rabbit's current diet. Record the types and amounts of hay, pellets, vegetables, and treats offered daily. Note your rabbit's body condition, fecal output, and any signs of dental or digestive problems. This baseline information will help you identify areas for improvement.

Step 2: Select an Appropriate Hay

Choose a high-quality timothy hay based on the visual, olfactory, and textural criteria described earlier. If your rabbit is an adult with no health concerns, select a timothy hay that is green, fragrant, and contains a mix of stems and leaves. If your rabbit is young, pregnant, nursing, or underweight, discuss whether alfalfa supplementation is appropriate with your veterinarian.

Step 3: Establish a Feeding Schedule

Rabbits should have unlimited access to hay at all times. Refill the hay feeder at least once daily, and more frequently if the rabbit consumes hay quickly. Remove soiled or contaminated hay daily to maintain hygiene.

For pellets, establish a consistent feeding schedule. Offer the measured daily portion at the same time each day, preferably in the evening when rabbits are most active. Monitor pellet consumption and adjust the portion if the rabbit is gaining or losing weight.

Step 4: Monitor Intake and Output

Track your rabbit's hay consumption and fecal output daily. A healthy adult rabbit produces a consistent volume of firm, round fecal pellets. Changes in fecal output, including reduced quantity, smaller pellet size, or soft stools, may indicate inadequate fiber intake or digestive problems.

Weigh your rabbit weekly or monthly to monitor body condition. A stable weight in an adult rabbit indicates that calorie intake is appropriate. Sudden weight loss or gain warrants investigation.

Step 5: Adjust Based on Observations

Use your observations to adjust the feeding plan. If your rabbit is not eating enough hay, try different presentation methods, offer a different cutting of timothy, or mix in a small amount of a preferred hay. If your rabbit is gaining weight, reduce the pellet portion and ensure hay remains the primary food source. If your rabbit shows signs of dental disease, such as drooling, reduced appetite, or preference for soft foods, seek veterinary care.

Records and Measurements for Monitoring Hay Quality and Intake

Tracking Hay Consumption

Maintaining records of hay consumption helps identify changes in appetite that may signal health problems. Weigh the hay offered and the hay remaining at the end of each day to calculate daily consumption. A simple kitchen scale can be used for this purpose.

Record the following information in a feeding log:

• Date and type of hay offered
• Weight of hay offered
• Weight of hay remaining
• Calculated daily consumption
• Fecal output assessment
• Any changes in eating behavior

Monitoring Hay Quality Over Time

Keep records of each hay purchase, including the source, purchase date, cutting, and your assessment of quality. Note any changes in color, smell, or texture that occur during storage. This information helps you identify reliable suppliers and recognize when hay has deteriorated.

Body Condition Scoring

Body condition scoring provides a standardized method for assessing whether your rabbit is at an appropriate weight. The scoring system typically uses a scale of 1 to 5, with 1 being emaciated and 5 being obese. A score of 3 indicates ideal body condition, where the spine and ribs can be felt but not seen, and there is a small amount of fat cover.

Score your rabbit's body condition monthly and record the results. Trends in body condition score are more informative than single measurements. A gradual increase or decrease in score indicates that dietary adjustments are needed.

Fecal Output Monitoring

Fecal output is a sensitive indicator of gastrointestinal health in rabbits. A healthy adult rabbit produces 200 to 300 fecal pellets per day, though this number varies with body size and food intake. Monitor the quantity, size, and consistency of fecal pellets daily.

Changes in fecal output that warrant attention include:

• A significant decrease in pellet quantity
• Smaller or misshapen pellets
• Soft, mushy, or watery stools
• The presence of mucus in the stool
• A reduction in cecotrope production

Persistent changes in fecal output should be evaluated by a veterinarian, as they may indicate gastrointestinal stasis, dental disease, or other health problems.

Common Failure Patterns in Timothy Hay Feeding

Failure Pattern 1: Inadequate Hay Consumption

The most common failure in rabbit feeding is inadequate hay consumption. Rabbits that prefer pellets or treats may eat insufficient hay, leading to dental disease, gastrointestinal stasis, and obesity. Signs of inadequate hay consumption include reduced fecal output, overgrown teeth, and weight gain.

Correction: Gradually reduce pellet portions while ensuring hay is always available. Offer hay in multiple locations and in different presentation forms. Some rabbits respond to hay that has been lightly misted with water or mixed with a small amount of a favorite herb.

Failure Pattern 2: Feeding Low-Quality Hay

Owners may unknowingly purchase low-quality hay that is yellow, dusty, or moldy. Low-quality hay provides less nutrition and may cause respiratory or digestive problems. Signs that hay quality is poor include a musty smell, visible mold, excessive dust, and a brown or yellow color.

Correction: Discard low-quality hay and purchase from a different source. Inspect hay before purchase whenever possible. If buying online, read reviews and choose a supplier with a reputation for quality.

Failure Pattern 3: Improper Storage Leading to Spoilage

Hay stored in damp or humid conditions can develop mold, which is dangerous for rabbits. Hay stored in direct sunlight can lose vitamin content. Hay stored on the floor can absorb moisture and become contaminated.

Correction: Store hay in a cool, dry, well-ventilated area, off the floor, and protected from direct sunlight. Use containers that allow air circulation. Inspect stored hay regularly and discard any that shows signs of deterioration.

Failure Pattern 4: Sudden Diet Changes

Abruptly switching a rabbit from one hay type to another, or from a low-fiber diet to a high-fiber diet, can cause digestive upset. The cecal microbial population requires time to adapt to changes in fiber type and content.

Correction: Make all diet changes gradually over seven to ten days. Mix the new food with the old food in increasing proportions to allow the digestive system to adapt.

Failure Pattern 5: Overfeeding Pellets and Treats

Rabbits that receive unlimited pellets or frequent treats may fill up on these foods and eat less hay. This pattern leads to obesity, dental disease, and digestive problems.

Correction: Measure pellet portions and limit treats to small amounts of rabbit-safe fruits and vegetables. Ensure that hay remains the primary component of the diet, making up approximately 80 percent of daily intake.

Limitations and Considerations

Individual Variation in Hay Preferences

Rabbits show individual variation in hay preferences. Some rabbits prefer first cutting timothy, which is stemmier and more abrasive, while others prefer second cutting, which is leafier and softer. Some rabbits may refuse timothy entirely and accept other grass hays such as orchard grass or meadow hay. The most important consideration is that the rabbit consumes adequate fiber, regardless of the specific grass hay used.

Seasonal and Regional Variation in Hay Quality

Timothy hay quality varies by growing region, harvest year, and cutting. Weather conditions during the growing season affect plant growth and nutrient content. Hay harvested in a drought year may be lower in nutrients than hay harvested in a favorable year. Hay harvested from different fields on the same farm may differ in quality.

These variations mean that the nutritional content of timothy hay is not constant. Owners should observe their rabbit's condition and adjust other dietary components as needed to maintain optimal health.

Hay as a Component of Complete Nutrition

Timothy hay is an essential component of a rabbit's diet but does not provide complete nutrition on its own. Rabbits require additional nutrients from pellets and fresh vegetables, including vitamins and minerals that may be insufficient in hay. The pellet portion of the diet provides these supplemental nutrients, while vegetables provide variety and additional hydration.

Research Limitations

The scientific literature on timothy hay for rabbits includes studies on fiber digestion, nitrogen utilization, and comparative nutrition. However, much of the research has been conducted in production settings with growing rabbits, and findings may not directly translate to pet rabbits with different management and health profiles. Owners should use research findings as general guidance while observing their individual rabbit's response to dietary changes.

Welfare and Safety Context

Respiratory Health Considerations

Hay dust and mold spores can affect respiratory health in both rabbits and humans. Rabbits are obligate nasal breathers and are sensitive to airborne irritants. Poor-quality hay that is dusty or moldy can cause sneezing, nasal discharge, and respiratory distress.

Animal farming environments, including those where hay is stored and handled, are associated with exposure to organic dust containing allergens, endotoxins, and microbial organisms. Microbial volatile organic compounds produced by fungi and bacteria can accumulate in confined animal buildings and pose health hazards to workers, including veterinarians (Microbial Volatile Organic Compounds (MVOCs) - rare cause of occupational asthma in two veterinarians). While this research focuses on occupational exposure in farming settings, it highlights the importance of minimizing dust and mold exposure when handling hay for rabbits.

To reduce respiratory risks:

• Select hay that is low in dust and free of visible mold
• Store hay in a dry, well-ventilated area
• Shake hay outdoors before offering it to the rabbit
• Consider wearing a dust mask when handling large quantities of hay
• Ensure the rabbit's enclosure has adequate ventilation

Gastrointestinal Health Considerations

The rabbit gastrointestinal tract is sensitive to dietary changes and inadequate fiber intake. Gastrointestinal stasis, a condition where the digestive tract slows or stops, is a medical emergency that requires immediate veterinary care. Signs of gastrointestinal stasis include reduced or absent fecal output, decreased appetite, lethargy, and signs of abdominal pain such as teeth grinding or a hunched posture.

Adequate fiber intake from timothy hay is the primary preventive measure for gastrointestinal stasis. Owners should monitor fecal output daily and seek veterinary care promptly if they observe signs of reduced gastrointestinal motility.

Dental Health Considerations

Dental disease is one of the most common health problems in pet rabbits. Inadequate hay consumption is a primary risk factor, as the abrasive action of chewing hay is necessary to wear down continuously growing teeth. Signs of dental disease include:

• Reduced appetite or refusal to eat
• Drooling or wet fur around the mouth
• Difficulty chewing or dropping food
• Weight loss
• Preference for soft foods over hay
• Visible overgrowth or misalignment of teeth

Rabbits showing signs of dental disease should be examined by a veterinarian experienced with rabbits. Dental disease often requires professional treatment, including tooth trimming or extraction, and cannot be resolved through dietary changes alone.

Professional Escalation Criteria

Seek veterinary care promptly if your rabbit shows any of the following signs:

• No fecal output for 12 to 24 hours
• Complete loss of appetite for more than 12 hours
• Lethargy or reluctance to move
• Signs of abdominal pain, including teeth grinding or a hunched posture
• Diarrhea or watery stools
• Visible blood in the stool
• Difficulty breathing or nasal discharge
• Excessive drooling or wet fur around the mouth
• Sudden weight loss
• Visible dental overgrowth or misalignment

These signs may indicate serious health conditions that require professional diagnosis and treatment. Do not attempt to treat these conditions at home without veterinary guidance.

Frequently Asked Questions

How much timothy hay should I feed my rabbit daily?

Adult rabbits should have unlimited access to timothy hay at all times. Hay should make up approximately 80 percent of the daily diet. Most rabbits will consume an amount of hay roughly equal to the size of their body each day, though individual intake varies. Refill the hay feeder at least once daily and monitor consumption to ensure your rabbit is eating adequate fiber.

Can I feed my rabbit only timothy hay and no pellets?

Timothy hay alone does not provide complete nutrition for rabbits. While hay should be the primary dietary component, rabbits also require nutrients from a measured portion of high-quality pellets and a small amount of fresh vegetables. Pellets provide supplemental vitamins and minerals that may be insufficient in hay alone. Consult your veterinarian for specific dietary recommendations for your rabbit.

How can I tell if timothy hay is fresh and high quality?

High-quality timothy hay is green in color, has a sweet grassy smell, and feels dry and crisp. It should contain a mix of stems, leaves, and seed heads. Avoid hay that is yellow or brown, has a musty or sour smell, feels damp, or contains visible mold or excessive dust. Purchase hay from reputable sources and inspect it before feeding.

What is the difference between first cutting and second cutting timothy hay?

First cutting timothy hay is harvested from the first growth of the season and tends to be stemmier, higher in fiber, and more abrasive. Second cutting hay comes from regrowth after the first harvest and is typically leafier, softer, and sometimes more palatable. Both can be appropriate for rabbits, though individual rabbits may show a preference for
