The Foundation of a Healthy Rabbit Diet

Feeding a rabbit correctly is one of the most important things you can do for their long-term health. Despite common assumptions, rabbits are not primarily vegetable eaters — their digestive system is built around fibrous grass, and getting this wrong can lead to serious, life-threatening health issues.

A healthy adult rabbit's diet should look roughly like this:

  • ~80% hay (unlimited, always available)
  • ~15% fresh leafy greens (daily variety)
  • ~5% high-quality pellets (measured portion)
  • Treats: occasional and fruit-based only (small amounts)

Hay: The Most Important Part of the Diet

Hay is not optional — it is the cornerstone of rabbit nutrition. It provides essential fibre to keep the digestive system moving, wears down continuously growing teeth, and keeps rabbits occupied throughout the day. A rabbit should eat roughly their body size in hay each day.

Best hay types for adult rabbits:

  • Timothy hay: The gold standard — ideal balance of fibre and nutrients.
  • Meadow hay: A popular alternative with a variety of grasses and dried flowers.
  • Orchard grass hay: Good option for rabbits who don't take well to timothy.

Note: Alfalfa hay is high in calcium and protein — suitable for young rabbits under 6 months, but not for adults.

Fresh Leafy Greens

Adult rabbits should receive a varied mix of fresh greens daily. Aim for 2–3 different types each day and rotate regularly. A good serving is approximately 1–2 cups per 2 kg of body weight.

Safe greens to feed regularly:

  • Romaine lettuce (not iceberg — it has very little nutritional value)
  • Kale (in moderation — high in calcium)
  • Bok choy
  • Cilantro (coriander)
  • Parsley
  • Basil
  • Watercress
  • Carrot tops (the green leafy part, not the carrot itself)

Pellets: Supplement, Not Staple

Good quality pellets can fill nutritional gaps, but should be used as a supplement to hay — not a replacement. Choose plain, grass-based pellets with no added seeds, dried fruit, or colourful "mixes." These extras are high in sugar and lead to selective eating.

A typical adult rabbit (around 2 kg) needs no more than 1/4 cup of pellets per day. Overfeeding pellets is a leading cause of obesity and dental disease in domestic rabbits.

Treats: What's Safe and What Isn't

Treats should be occasional — think once or twice a week in small amounts. The best natural treats include:

  • Small pieces of apple (no seeds — these contain cyanide compounds)
  • A few blueberries or raspberries
  • A small slice of strawberry
  • A thin slice of banana (very sugary — limit strictly)

Foods to Avoid Completely

The following are dangerous and should never be fed to rabbits:

  • Chocolate, sweets, or any processed human food
  • Onions, garlic, leeks, or chives
  • Avocado
  • Rhubarb
  • Iceberg lettuce (causes digestive issues)
  • Potatoes or other starchy vegetables
  • Muesli-style rabbit mixes (selective eating leads to imbalanced nutrition)

Water: Essential and Often Overlooked

Fresh, clean water must be available at all times. Most rabbits drink more readily from a heavy ceramic bowl than a bottle. Change the water daily and wash the bowl regularly to prevent bacterial build-up.
