What Should Rabbits Eat? A Complete Nutrition Guide

Rabbits have specialized digestive systems that require a specific diet to stay healthy. Unlike what pet store packaging might suggest, rabbits shouldn't eat primarily pellets. A proper rabbit diet is based on hay, supplemented with fresh vegetables, limited pellets, and occasional treats. Getting nutrition right prevents common (and serious) health issues.

The Foundation: Unlimited Hay

Hay should make up 80-85% of your rabbit's diet. Timothy hay is ideal for adult rabbits. Young rabbits (under 7 months) can have alfalfa hay, which is higher in calcium and protein. Hay provides essential fiber that keeps the digestive system moving and wears down constantly-growing teeth. Rabbits should always have access to fresh hay—a rabbit-sized amount daily is a pile as big as their body.

Fresh Vegetables Daily

Offer 1-2 cups of fresh vegetables per 2 pounds of body weight daily. Safe options include romaine lettuce, cilantro, parsley, bok choy, carrot tops (not carrots themselves often), and dandelion greens. Introduce new vegetables slowly to avoid digestive upset. Avoid iceberg lettuce (no nutritional value), cabbage, and beans (cause gas). Dark leafy greens should be the bulk; limit high-oxalate vegetables like spinach and kale.

The Role of Pellets

Despite marketing, pellets should be limited—about 1/4 cup per 5 pounds of body weight for adults. Choose plain, timothy-based pellets without colorful bits (which are sugary). Young rabbits can have unlimited alfalfa pellets until 7 months. Pellets provide concentrated nutrition but aren't necessary in large quantities if hay and vegetables are adequate. Some rabbit experts advocate for a pellet-free diet with sufficient hay and greens.

Treats in Moderation

Treats should be rare—maximum 1-2 tablespoons daily. Safe treats include small pieces of banana, apple (no seeds), strawberry, or carrot. Avoid commercial 'yogurt drops' and sugary treats—despite their prevalence in pet stores, they can cause serious digestive problems. Rabbits have sweet teeth, but their systems can't handle sugar well. Use treats for bonding and training, not as dietary staples.

Water is Essential

Fresh, clean water must be available 24/7. A rabbit can drink as much as a small dog. Water bottles and bowls both work; some rabbits prefer bowls since they're more natural. Change water daily. Dehydration can quickly lead to serious GI problems. If your rabbit isn't drinking (and it's not very high water-content veggie day), contact your vet—decreased drinking is often a sign of illness.

Veterinarian's Insight: Preventing GI Stasis

As an exotic animal specialist, I see many rabbits with GI stasis, a life-threatening condition where the digestive system slows or stops. The primary cause is inadequate fiber from hay. Even a few days without hay can put a rabbit at risk. I recommend checking hay consumption daily—your rabbit should be eating hay constantly throughout the day. If you notice decreased hay consumption, lethargy, or small, hard stools, contact your vet immediately.

Case Study: Thumper's Dietary Transformation

Thumper, a 2-year-old Holland Lop, was brought to the clinic with GI stasis. His diet consisted primarily of pellets and treats, with minimal hay. After hospitalization and fluid therapy, Thumper's owner transitioned him to a diet of unlimited timothy hay, daily vegetables, and limited pellets. Within a month, Thumper's digestive health improved dramatically. He became more active, had regular stools, and showed no signs of GI issues. This case highlights the importance of proper nutrition in preventing serious health problems.

Rabbit Diet Checklist by Age

Tailor your rabbit's diet to their life stage: 1. Baby rabbits (0-7 months): Unlimited alfalfa hay, unlimited alfalfa pellets, small amounts of vegetables introduced gradually. 2. Adult rabbits (7 months-6 years): Unlimited timothy/orchard grass hay, 1-2 cups vegetables per 2 lbs body weight, 1/4 cup pellets per 5 lbs body weight. 3. Senior rabbits (6+ years): Unlimited soft, leafy hay (timothy or orchard grass), increased vegetables, reduced pellets, regular veterinary check-ups.

Common Dietary Myths Debunked

There are several common myths about rabbit nutrition: 1. Myth: Rabbits need a variety of pellets. Fact: Plain, timothy-based pellets are best. 2. Myth: Rabbits can live on vegetables alone. Fact: Hay is essential for digestive health. 3. Myth: All greens are safe. Fact: Some greens like iceberg lettuce have no nutritional value. 4. Myth: Rabbits need fruit daily. Fact: Fruit should be an occasional treat due to high sugar. 5. Myth: Pellets are the most important part of the diet. Fact: Hay should be the foundation.
