Rabbit Nutrition in India: What to Feed Your Bunny (NRC-Based Guide)

Rabbits are hindgut fermenters, which means they digest food through a specialized process in the cecum (a part of the large intestine) where bacteria break down plant fibers. This system is extraordinarily sensitive. Unlike dogs and cats, rabbits cannot vomit — once something enters their digestive system, it must pass through. A diet low in fiber causes the gut to slow (GI stasis), which is life-threatening within 24-48 hours. A diet high in sugar or simple carbohydrates disrupts cecal bacteria, causing dysbiosis, bloating, and diarrhea. Rabbits also practice cecotrophy — they eat certain of their own droppings (cecotropes) which are nutrient-rich and essential to their health. This is normal and should never be discouraged. Understanding this system explains why hay is not optional — it is life-sustaining.

The most widely accepted and NRC-consistent feeding framework for rabbits is the 80-10-10 rule:

Component | Proportion | Examples

Hay | 80% | Timothy hay, orchard grass, meadow hay. Must be available unlimited, 24/7. This is the most critical component.

Fresh Veg | 10% | Leafy greens: romaine lettuce, bok choy, cilantro, parsley, kale (in moderation), carrot tops. 1 packed cup per 2 lbs body weight daily.

Pellets | 10% | High-fiber pellets (min 18% fiber). 1/4 cup per 5 lbs body weight for adults. Unlimited for young rabbits under 7 months.

Fruits are occasional treats only (1-2 tablespoons per day maximum due to sugar content). Water must always be available — most rabbits prefer a bowl over a bottle.

The NRC's 'Nutrient Requirements of Rabbits' provides these guidelines for adult maintenance rabbits:

Nutrient | NRC Recommendation

Crude Protein | 12-17% of dry matter

Crude Fiber | 14-20% of dry matter (minimum 14% essential for gut health)

Crude Fat | 2-5% of dry matter

Calcium | 0.6-1.0% of dry matter

Phosphorus | 0.4-0.8% of dry matter

Vitamin A (IU/kg) | 6000-10000

Vitamin D (IU/kg) | 900-1000

Vitamin E (mg/kg) | 40-70

Growing rabbits, pregnant does, and lactating does have significantly higher protein and energy requirements. A diet based primarily on unlimited timothy hay naturally meets fiber requirements when supplemented with appropriate greens and pellets.

Safe Vegetables and Herbs:

Romaine lettuce, bok choy, cilantro, parsley, dill, basil, mint, carrot tops (not the carrot itself in large amounts — high sugar), spinach (in moderation — high oxalates), kale (small amounts), bell peppers, cucumber.

Safe Fruits (treats only, small amounts):

Apple (no seeds), banana, mango, papaya, strawberries, blueberries.

Unsafe / Toxic Foods:

Avocado (toxic), onion and garlic (toxic — cause hemolytic anemia), potato and raw potato leaves (toxic), rhubarb (toxic), iceberg lettuce (very low nutrition, causes diarrhea), beans and legumes (disrupt gut bacteria), seeds and nuts (too high in fat), bread, roti, and cooked rice (disrupt cecal bacteria).

Common Indian foods to avoid: dal, cooked rice, roti, idli, dosa batter, spiced food, dairy products, and any fried food.

Pawsnexus vets in Bengaluru frequently see rabbits brought in after owners fed them well-intentioned but harmful foods. Dal and legumes: the plant proteins and complex sugars in lentils disrupt the cecal microbiome severely, causing bloating and potentially fatal GI stasis. Roti and bread: simple carbohydrates ferment rapidly in the cecum, causing dysbiosis and loose cecotropes. Cows milk and dairy: rabbits are lactose intolerant after weaning — dairy causes severe diarrhea. Excess fruit: the natural sugars, even from healthy fruits, can disrupt cecal bacteria in large amounts — limit to a tablespoon or two daily at most. Spinach in excess: high oxalic acid content can cause kidney stones over time when fed as a staple rather than an occasional green.

Rabbits require approximately 50-150ml of water per kilogram of body weight per day. In Bengaluru's warmer months (March-May), a 2kg rabbit may need 200-300ml daily. Dehydration in rabbits accelerates GI stasis — a rabbit that stops drinking is at serious risk within hours. Provide water in a heavy ceramic bowl rather than a bottle, as most rabbits drink more from bowls. Change water twice daily. In warm weather, place water bowls in a cool location and refresh frequently. If your rabbit seems to have stopped eating and drinking, contact Pawsnexus at +91 85500 46444 immediately — GI stasis can become fatal within 24 hours and requires urgent veterinary care.
