What Do Rabbits Eat? The Complete Diet Guide

Rabbit digestion is unlike any other pet’s. They process food twice — producing special night droppings they re-eat — and their digestive system moves continuously. When it stops, the condition called gut stasis is fatal within 24 to 48 hours. Nearly every case of stasis traces back to diet, which makes what you feed your rabbit the most important thing you control.

This guide covers the complete diet: the unlimited staple, daily vegetables, treat limits, and the foods that kill.

The Foundation: Unlimited Hay

Hay is 80 to 90 percent of a rabbit’s diet, and it should be available at all times:

• Timothy hay is the adult standard — appropriate fiber, appropriate calcium.
• Orchard grass and meadow hay add variety and are equally good staples.
• Alfalfa hay is for growing rabbits under seven months and pregnant or nursing mothers — the higher calcium and protein cause problems in adult rabbits, including urinary sludge.

Hay does three jobs no other food does:

• Wears down teeth. Rabbit molars grow continuously — up to five inches a year. Without hay to grind, teeth overgrow into spurs that cut the tongue and prevent eating entirely.
• Keeps the gut moving. Long fiber is what moves food through a rabbit’s digestive tract. Low fiber is the direct cause of gut stasis.
• Prevents boredom. Chewing hay occupies rabbits and reduces destructive chewing of furniture and baseboards.

A rabbit that stops eating hay is a rabbit on the way to an emergency. Treat any hay refusal as a vet call, not a preference.

Measured Pellets

Pellets are a supplement, not the main course — a common and harmful mistake:

• Amount: one-quarter cup per five pounds of body weight daily, measured.
• Type: plain timothy-based pellets, no mixes. The colorful bags with seeds, dried corn, and yogurt drops cause selective eating — rabbits pick the treats and leave the nutrition, then get fat and malnourished simultaneously.
• No muesli-style mixes, ever. They are linked to dental disease and obesity.

Daily Fresh Vegetables

Leafy greens are the daily fresh component. Introduce new vegetables one at a time over several days, watching for soft stool:

• Romaine lettuce, red and green leaf lettuce — daily staples
• Cilantro, parsley, basil, mint — herbs are well received and safe
• Carrot tops, broccoli leaves, kale (moderate), bok choy — rotate through
• Amount: roughly two cups of varied greens per five pounds of body weight daily

Gradual introduction matters. A sudden pile of new vegetables causes diarrhea, and diarrhea in rabbits is dangerous fast.

Fruit: Rare Treats Only

Fruit is candy to a rabbit. Sugar disrupts the gut flora that digestion depends on:

• A thumbnail-sized piece once or twice a week, maximum.
• Apple, banana, strawberries, blueberries are the common options — always in tiny amounts.
• Never daily, never large portions. Rabbits will beg for fruit constantly; their digestion cannot handle what their enthusiasm suggests.

Foods That Are Dangerous or Fatal

These cause illness or death — commit the list to memory:

• Iceberg lettuce — almost no nutrition, causes diarrhea, contains laudanum-like compounds in quantity
• Bread, crackers, pasta, and other processed carbs — cause fatal gut stasis by clogging the digestive tract
• Avocado — toxic, contains persin
• Chocolate, caffeine, alcohol — toxic
• Onion, garlic, leeks, chives

— toxic, cause blood disorders

• Potatoes and tomato leaves — toxic parts of nightshade plants
• Beans, peas, and other legumes — gas and digestive disruption
• Nuts and seeds — high fat, low fiber, wrong nutrition profile
• Meat, dairy, eggs — rabbits are herbivores; animal products cause severe digestive disease
• Rhubarb — toxic
• Houseplants generally — most are toxic; keep them out of reach

Water: Always Available

• Heavy ceramic bowls are better than bottles — rabbits drink more from bowls, and bottles get clogged and go unnoticed.
• Fresh water daily, checked twice.
• A rabbit drinking far more than usual may have dental pain or kidney disease — a vet call.

Gut Stasis: The Emergency to Know

The rabbit digestive tract must keep moving. When it slows or stops — usually from too little fiber, too much sugar, stress, pain, or an underlying illness — gas builds, the rabbit stops eating, and the condition becomes fatal quickly.

Warning signs:

• Small droppings, then no droppings at all
• Hunched posture, teeth grinding, pressing the belly to the floor
• Loud gut noises, or complete silence where gurgles normally are
• Refusing hay or food for even half a day

Gut stasis is a same-day emergency vet visit. Do not attempt home treatment, do not wait overnight. The window is hours, and treatment involves pain management, motility drugs, and supportive care — all professional.

Frequently Asked Questions

Can rabbits eat carrots every day?

Carrots are a root vegetable, not a leafy green — higher in sugar than most rabbit foods. A small piece a few times a week is fine; daily is too much sugar. The cartoon association between rabbits and carrots is exactly backwards for real diets.

Do rabbits need pellets at all?

Hay plus varied greens can be a complete diet for adult rabbits. Pellets add guaranteed nutrition and are the standard recommendation — but hay remains the foundation regardless.

Why does my rabbit eat its own droppings?

Night droppings (cecotropes) are soft, shiny, and nutrient-dense — rabbits re-ingest them to extract vitamins produced by gut fermentation. It is normal and essential. Firm daytime droppings are waste.

How do I switch rabbit foods safely?

Over seven to ten days, mixing increasing proportions of the new food. Sudden changes disrupt the gut flora and cause diarrhea — and diarrhea in rabbits is an urgent situation.

The Bottom Line

Unlimited timothy hay, a measured quarter-cup of plain pellets, two cups of varied greens daily, and fruit as an occasional thumbnail treat. Never bread, iceberg lettuce, avocado, or nuts. Learn the stasis warning signs — small or absent droppings, hunched posture, gut silence — because that condition kills within a day and needs a vet immediately. Get the diet right and rabbits live seven to ten healthy years; get it wrong and gut stasis is the most likely outcome.
