What do rabbits eat is one of the most searched questions in small animal care, and the answer matters more than most new rabbit keepers realize. Rabbits have a uniquely sensitive digestive system built around continuous fiber processing. When that system is disrupted, by the wrong foods, insufficient hay, or sudden dietary changes, the consequences range from soft cecotropes and digestive discomfort to life-threatening GI stasis. Getting rabbit nutrition right from the beginning is one of the most important things you can do for the long-term health of any rabbit on your homestead.
Key Takeaways
The Foundation: What Do Rabbits Eat for Digestive Health?
Rabbits are hindgut fermenters with a digestive system unlike most other domestic animals. Food passes through the stomach and small intestine, where nutrients are absorbed, then into the cecum, a large fermentation chamber where beneficial bacteria break down fiber into nutrients the rabbit can use. The rabbit then produces two types of droppings: hard fecal pellets, which are waste, and cecotropes, soft nutrient-dense droppings that the rabbit re-ingests directly from its hindquarters.
This system functions correctly only when the rabbit receives a continuous supply of long-stemmed fiber from hay. Without adequate hay, cecal function slows, gas accumulates, and GI stasis, the slowing or stopping of digestive motility, can develop rapidly. GI stasis is a medical emergency in rabbits that can kill within 24 to 48 hours. The single most important element of what rabbits eat is grass hay, and it must be available without restriction at all times.
Hay for Rabbits
Timothy hay is the gold standard hay for adult rabbits. It has the appropriate calcium-to-phosphorus ratio, is high in long-stem fiber, and is widely available from farm supply stores and online suppliers. Orchard grass hay is an excellent alternative with slightly softer texture that some rabbits prefer. Both are appropriate as the primary hay for adult meat rabbits.
Alfalfa hay is high in calcium and protein, which makes it appropriate for young rabbits under 6 months and nursing does, but inappropriate as a staple for adult rabbits. Feeding alfalfa hay to adult rabbits long-term contributes to urinary sludge, kidney stress, and obesity from the elevated caloric and protein content.
Provide hay in a rack or manger positioned to keep it clean and dry. Hay piled on a wire cage floor quickly becomes soiled and unappealing. A simple J-feeder or hay rack attached to the side of the cage maintains accessibility and cleanliness simultaneously.
Pellets: How Much Do Rabbits Eat?
Commercial rabbit pellets are a concentrated nutrition source that complements hay in what rabbits eat, providing vitamins, minerals, and additional protein in a consistent, convenient form. Adult meat rabbits need 4 to 6 ounces of pellets per day, approximately a quarter to a third of a cup. Does in late pregnancy and nursing does with large litters can be fed pellets free-choice to support the elevated nutritional demands of reproduction and lactation.
Choose a pellet with a minimum 18% fiber content and 15 to 16% crude protein for adult meat rabbits. Higher fiber pellets are preferable because they encourage continued hay consumption rather than replacing it. Avoid pellets with seed mixes, dried fruit pieces, or colorful additives marketed as treats. These add sugar and calories without nutritional benefit and encourage rabbits to sort through pellets selectively rather than consuming the full ration.

Fryer rabbits being grown out for meat can be fed pellets more liberally, up to free choice, to maximize growth rate during the 8 to 12 week grow-out period. The goal for fryers is rapid weight gain within a compressed timeline rather than long-term metabolic health, which changes the feeding equation compared to breeding stock management.
Fresh Vegetables and Greens
Fresh vegetables and leafy greens are valuable additions to what rabbits eat, providing variety, hydration, and additional micronutrients. They are supplemental, not foundational, and must be introduced carefully.
Safe vegetables and greens for rabbits include:
- Leafy greens: romaine lettuce, green leaf lettuce, kale, collard greens, mustard greens, and bok choy
- Herbs: parsley, cilantro, basil, dill, and mint
- Root vegetables in small quantities: carrot tops (more appropriate than the root itself), beet greens, and turnip greens
- Cruciferous vegetables in moderation: broccoli leaves and stems, Brussels sprout leaves
Introduce new vegetables one at a time over one to two weeks and limit quantities to a few tablespoons per day initially. A rabbit that receives a large quantity of a new vegetable can develop diarrhea or cecal dysbiosis that progresses to more serious digestive problems. Once a rabbit has been eating a specific vegetable regularly without issue, you can gradually increase the amount.
The carrot body, not the greens, deserves specific mention. Carrots are high in sugar relative to their fiber content and should be fed as an occasional treat rather than a daily addition. The same applies to fruit, which rabbits find highly palatable but which contributes sugar without useful fiber.
What Rabbits Should Not Eat
Understanding what rabbits should not eat is as important as knowing what they can. Rabbits will sometimes nibble on unsafe foods without immediate visible consequence, which creates the false impression that those foods are tolerable. Cumulative exposure to toxic or inappropriate foods often shows up in health problems that are difficult to trace back to the dietary source.
Never feed rabbits:
- Iceberg lettuce: extremely low nutritional value and high water content that causes diarrhea
- Rhubarb leaves: contain oxalic acid in toxic concentrations
- Potato and tomato leaves: nightshade family, toxic to rabbits
- Onions, garlic, and leeks: toxic even in small quantities, causing blood disorders
- Avocado: toxic in all forms
- Chocolate and caffeinated products: obvious toxicity
- Seeds, nuts, and dried corn: high fat and carbohydrate content, indigestible hulls
- Any moldy food: mycotoxins are dangerous even in small amounts
Sugary treats marketed for rabbits, including yogurt drops and seed sticks, should not be fed. The sugar content disrupts cecal bacterial balance and contributes to obesity and dental problems.
Water Requirements
Fresh water must be available to rabbits at all times. An adult meat rabbit drinks 4 to 10 ounces of water per day depending on ambient temperature and diet moisture content. Rabbits eating primarily dry hay and pellets drink more than those receiving daily fresh greens. In summer heat, water consumption increases significantly and a rabbit that runs out of water will reduce feed intake within hours.
Water bowls and sipper bottles both work, but sipper bottles require more frequent cleaning to prevent bacterial biofilm buildup in the tube. Heavy ceramic bowls or stainless steel crocks attached to the cage are easier to clean and monitor daily. In freezing temperatures, heated water bowls or twice-daily water changes prevent the frozen water that leaves outdoor rabbits without hydration.
According to the House Rabbit Society, a diet based on unlimited grass hay, limited high-fiber pellets, and fresh vegetables in controlled quantities supports the digestive health and longevity of domestic rabbits more reliably than any other feeding approach.

Frequently Asked Questions About What Rabbits Eat
How much hay should a rabbit eat per day?
Hay should be available without restriction at all times. A rough guideline is that a rabbit should consume a pile of hay approximately the size of its own body each day. Hay consumption naturally decreases slightly when other foods are provided, but a rabbit that is eating very little hay regardless of what else is available should be evaluated for dental problems or underlying illness.
Can rabbits eat grass from the yard?
Fresh grass from the yard is safe for rabbits in moderate quantities, provided it has not been treated with pesticides, herbicides, or fertilizers. Introduce fresh grass gradually, as rabbits not accustomed to it can develop loose droppings. Wet grass should be dried slightly before feeding to reduce excess moisture. Dried grass from the yard is essentially the same as hay and is safe in any quantity.
Can rabbits eat fruit?
Yes, in very small amounts as an occasional treat. Fruit is high in sugar relative to fiber, and too much disrupts the cecal bacterial balance that rabbit digestion depends on. A tablespoon of apple (without seeds), a few blueberries, or a small strawberry once or twice a week is an appropriate treat level for an adult rabbit.
Do meat rabbits eat differently than pet rabbits?
The nutritional principles are the same: unlimited hay, limited pellets, fresh greens in moderation. Fryer rabbits being grown for meat are often fed pellets more liberally than breeding stock to maximize growth rate during the 8 to 12-week grow-out. Breeding does and bucks are managed on a maintenance ration similar to pet rabbits, with increases during late pregnancy and lactation.
What vegetables can rabbits eat every day?
Romaine lettuce, green leaf lettuce, cilantro, parsley, and kale are all appropriate daily greens for rabbits that have been gradually acclimated to them. Rotate through a variety rather than feeding the same vegetable every day to provide nutritional diversity. Keep total daily greens to a few packed cups for an adult rabbit and adjust downward if droppings become soft or loose.
