Getting Rabbit Nutrition Right Makes All the Difference
When I brought home my first rabbit, I made a classic rookie mistake: I filled a bowl with colorful pellet mix from the pet store and thought I was doing great. It took a vet visit and some serious reading before I understood that rabbit nutrition is nothing like feeding a hamster or guinea pig. Rabbits have incredibly sensitive digestive systems, and what you feed them directly impacts their lifespan, energy levels, and overall happiness.
If you're wondering what do rabbits eat, the short answer is: mostly hay. But there's a lot more nuance to it than that. Let me walk you through everything I've learned over years of keeping rabbits healthy and thriving.
Hay: The Foundation of Every Rabbit's Diet
This is the single most important thing to understand about rabbit nutrition: hay should make up 80-85% of your rabbit's diet. Not pellets. Not vegetables. Hay. Specifically, grass hays like Timothy hay, orchard grass, oat hay, or meadow hay.
Why is hay so critical? Two reasons. First, the long fiber strands keep your rabbit's gut moving properly. Rabbits have a specialized digestive system called hindgut fermentation, and without constant fiber intake, things can go very wrong very fast — we're talking GI stasis, which is a genuine emergency. Second, the chewing motion required to grind down hay wears down your rabbit's teeth, which grow continuously throughout their life. Without enough hay, teeth can overgrow and cause painful abscesses and difficulty eating.
A good rule of thumb: your rabbit should eat a body-sized pile of hay every single day. That sounds like a lot, and it is. I go through a large bag of Timothy hay every couple of weeks with two rabbits. It's the biggest ongoing expense, but it's non-negotiable.
What About Alfalfa Hay?
Alfalfa is higher in calcium and calories than grass hays. It's appropriate for baby rabbits under 6 months who need the extra nutrients for growth, and for pregnant or nursing does. For adult rabbits, though, stick with Timothy or other grass hays. Too much alfalfa in adults can contribute to bladder sludge and obesity.
Fresh Vegetables: The Daily Salad
After hay, fresh vegetables are the next most important part of your rabbit's diet. Aim for about 1-2 packed cups of fresh greens per day for every 2 pounds of body weight. Variety is key here — rotate through different options to provide a range of nutrients.
Great Daily Greens
These leafy greens can be offered daily and should form the base of the veggie portion:
- Romaine lettuce — a staple in our house, never iceberg though
- Cilantro — my rabbits go absolutely wild for this
- Parsley — both flat-leaf and curly varieties work
- Spring mix — convenient and usually a good blend
- Bok choy — a great option with nice crunch
- Watercress — packed with nutrients
- Endive and escarole — excellent variety options
Greens to Rotate (Higher in Oxalates)
These are perfectly safe but should be rotated rather than given daily due to higher oxalic acid content:
- Kale
- Spinach
- Swiss chard
- Mustard greens
- Beet greens
I typically pick 3-4 different greens each shopping trip and mix them together for each meal. My rabbits seem to appreciate the variety, and it keeps things nutritionally balanced.
Pellets: A Supplement, Not the Main Course
Here's where a lot of new owners get confused. Pellets are fine as a small supplement, but they shouldn't be the star of the show. For adult rabbits, the general recommendation is about 1/4 cup of plain Timothy-based pellets per 5 pounds of body weight per day.
When choosing pellets, look for:
- Timothy hay as the first ingredient
- No colorful bits, seeds, dried fruit, or yogurt drops mixed in
- At least 18% fiber content
- Around 14-16% protein for adults
- Low calcium (under 1%)
Those fancy "gourmet" mixes with dried banana chips and corn pieces? Skip them. They're the rabbit equivalent of junk food, and rabbits will pick out the sugary bits and ignore the nutritious pellets. Plain, boring pellets are what you want.
Fruits and Treats: Keep It Minimal
Rabbits have a serious sweet tooth, and they'll happily devour fruit if you let them. But fruit is high in sugar, and rabbit digestive systems aren't built to handle much of it. Think of fruit as an occasional treat — no more than 1-2 tablespoons per day for a medium-sized rabbit.
Safe fruit options include:
- Apple slices (remove seeds — they contain cyanide compounds)
- Blueberries
- Strawberries (mine love the leafy tops too)
- Banana (very small amounts — this is basically candy to rabbits)
- Raspberry
- Pear
- Papaya (some owners swear it helps with hairballs)
I use tiny fruit pieces as training rewards. A single blueberry is enough to get my rabbit's attention during clicker training sessions. There's no need to be generous with sugar.
Water: Often Overlooked but Vital
Fresh, clean water must be available 24/7. Some rabbits prefer water bottles, others prefer bowls. I've found that most rabbits actually drink more from a heavy ceramic bowl than a bottle, and staying hydrated is crucial for digestive health. Just make sure the bowl is heavy enough that it won't tip over — rabbits can be surprisingly destructive.
Change the water daily and wash the container regularly. In hot weather, I sometimes drop an ice cube in the bowl, which my rabbits seem to enjoy.
Foods That Are Dangerous for Rabbits
This is critical. Some foods that seem harmless can be genuinely dangerous:
- Iceberg lettuce — very low nutrition and contains lactucarium, which can cause digestive issues
- Potatoes and potato leaves — toxic to rabbits
- Rhubarb — all parts are toxic
- Onions, garlic, leeks, chives — can damage red blood cells
- Avocado — contains persin, which is toxic
- Chocolate — toxic, just like for dogs
- Bread, pasta, crackers, cereal — starchy foods that can cause dangerous bloating
- Nuts and seeds — too high in fat, can cause digestive blockages
- Yogurt drops and commercial treats — most are loaded with sugar and artificial ingredients
If your rabbit accidentally eats something from this list, contact your rabbit-savvy veterinarian immediately. Don't wait to see if symptoms develop.
Feeding Schedule: How I Structure Meals
Here's what a typical day looks like in our house:
- Morning: Refresh hay supply (unlimited), serve fresh greens
- Evening: Measured pellet portion, more fresh greens, top off hay
- Throughout the day: Make sure hay rack never runs empty, fresh water always available
Rabbits are naturally crepuscular — most active at dawn and dusk — so this schedule aligns with when they're most eager to eat. Consistency matters. Try to feed at roughly the same times each day.
Special Considerations for Baby Rabbits
Baby rabbits (under 6 months) have slightly different dietary needs:
- Unlimited alfalfa hay is appropriate for growing bunnies
- Unlimited alfalfa-based pellets until about 3 months, then gradually introduce measured portions
- Start introducing vegetables slowly around 12 weeks — one new veggie at a time, in small amounts
- Watch for any soft stool when introducing new foods and pull back if you see it
The transition from baby to adult diet should happen gradually between 6-12 months. Slowly swap alfalfa for Timothy hay and reduce pellet quantities to adult levels.
Signs Your Rabbit's Diet Needs Adjustment
Watch for these red flags that might indicate nutritional issues:
- Soft or mushy droppings — often means too many pellets or vegetables, not enough hay
- Small, dry, or irregular droppings — could indicate dehydration or insufficient fiber
- Weight gain — reduce pellets and treats, increase hay
- Overgrown teeth — usually means not enough hay to wear them down
- Uneaten cecotropes — those soft, grape-like clusters rabbits normally re-eat; if left uneaten, the diet may be too rich
When in doubt, consult a rabbit-savvy veterinarian. Regular vet check-ups should always include a discussion about diet.
