Hay vs Pellets: What a Rabbit Should Really Eat
Hay vs pellets for rabbits explained: why grass hay should be 80% of the diet, how much pellet to feed, and the gear that keeps it tidy.
If you are new to rabbits, the bag of pellets at the pet store can feel like the obvious main meal. It is tidy, it looks like food, and your bunny will happily gobble it up. Here is the gentle truth that surprises most new owners: pellets are the small supporting act, and grass hay is the star. A rabbit's whole digestive system is built to process big volumes of fibrous grass, slowly, all day long. Let us walk through how hay and pellets compare and how to give each the right role.

Why hay is the foundation, not the pellets
Rabbits are lagomorphs with a delicate, fast-moving digestive tract that depends on a constant supply of long fiber. That fiber keeps the gut contracting and pushing food along, which prevents a dangerous slowdown called GI stasis. Grass hay delivers exactly this: tough, stringy strands that a rabbit chews for hours. Veterinary nutritionists and the House Rabbit Society agree that grass hay should make up roughly 80 percent of what a rabbit eats every day.
There is a dental reason too. A rabbit's teeth grow continuously throughout its 8 to 12 year life. The only thing that keeps them properly worn down is the long, grinding, side-to-side chew that hay demands. Without enough hay, molars can develop painful spurs and the front teeth can overgrow, a problem called malocclusion that often needs veterinary correction.
So what are pellets actually for?
Pellets are a concentrated supplement that adds a reliable baseline of vitamins, minerals, and protein. Think of them as a daily multivitamin, not a meal. A good pellet is uniform and timothy-based, meaning every piece is the same balanced formula. Avoid colorful muesli mixes with seeds, dried fruit, and crunchy loops, because rabbits will pick out the sugary bits and leave the healthy ones, which causes imbalance and weight gain.
The portion matters enormously. A widely used guideline is about one quarter cup of pellets per five pounds of adult body weight per day. That is a small handful, not a full bowl. When pellets are overfed, a rabbit fills up and eats less hay, which undermines the whole diet.
Hay vs pellets at a glance
| Factor | Grass Hay | Pellets |
|---|---|---|
| Share of diet | About 80 percent | Small daily supplement |
| How much | Unlimited, refilled all day | About 1/4 cup per 5 lbs adult |
| Fiber content | High, long strands | Crushed and compressed |
| Dental benefit | Excellent, grinds molars | Minimal |
| Gut motility | Keeps gut moving | Limited support |
| Overfeeding risk | Very low | Obesity, soft stools, less hay eaten |
Building the everyday bowl and rack
A simple, vet-friendly daily routine looks like this. Keep a hay rack or feeder full of fresh grass hay at all times so your rabbit can graze whenever it likes. A wire rack such as a metal hay feeder keeps the strands clean and off the floor, which reduces waste and keeps soiled hay out of the mix. Each morning, measure out the pellet portion into a heavy bowl. Add a daily handful of safe leafy greens, and reserve treats for tiny, occasional rewards.
Watch the hay-to-pellet ratio by eye. If your rabbit is leaving hay but emptying the pellet bowl, you are likely feeding too many pellets. Cut back gradually and the hay appetite usually returns. Cecotropes, the soft clusters a rabbit re-ingests, are a normal sign of a healthy fiber-rich diet, so do not be alarmed by them.
Special cases: babies, seniors, and recovery
Young rabbits under about seven months and underweight or recovering rabbits have different needs and may be fed alfalfa-based hay and pellets for extra calcium, protein, and calories. Adults should transition to timothy or other grass hay. Any rabbit that stops eating, produces fewer or smaller droppings, or seems hunched and quiet needs same-day attention from a rabbit-savvy exotic vet, because appetite loss can escalate quickly.
Our Recommendation
The verdict is clear and reassuring: make unlimited grass hay the foundation of your rabbit's diet, and treat pellets as a small measured supplement of about one quarter cup per five pounds of adult weight. Hay drives the gut, protects the teeth, and satisfies the natural urge to forage, while quality timothy pellets fill in nutritional gaps. Keep a feeder rack stocked with fresh Oxbow Western Timothy Hay, portion out Oxbow Essentials Adult pellets once a day, and you will have the everyday diet most exotic vets recommend. Always confirm portions for your individual rabbit with a rabbit-savvy vet.

Frequently Asked Questions
Can a rabbit live on pellets alone?
No, and it can make a rabbit sick. Pellets are concentrated and low in the long fiber a rabbit's gut needs to keep moving. A pellet-only diet is linked to obesity, soft stools, dental disease, and GI stasis. Grass hay should make up about 80 percent of the diet so your rabbit chews for hours and wears down its constantly growing teeth. Pellets are a small daily supplement, never the main meal.
How much hay does a rabbit need each day?
Offer unlimited grass hay, all day, every day. A healthy adult rabbit should eat a pile of hay roughly equal to its own body size daily. Keep the hay rack full so fresh strands are always available, since rabbits graze in many small sittings. Hay supports dental health, gut motility, and natural foraging behavior. If your rabbit's hay intake drops, contact a rabbit-savvy exotic vet promptly, as reduced appetite can signal trouble.
How many pellets should I give my adult rabbit?
A common guideline is about one quarter cup of quality timothy-based pellets per five pounds of adult body weight per day. Measure it, do not free-feed from a full bowl. Overfeeding pellets fills a rabbit up so it eats less hay, which is exactly backward. If your rabbit is overweight or barely touching its hay, talk with your exotic vet about trimming the pellet portion further.
Are timothy pellets better than alfalfa pellets?
For most adult rabbits, yes. Timothy-based pellets are lower in calcium, protein, and calories, which suits a grown rabbit's needs. Alfalfa-based pellets are richer and are meant for babies under about seven months and for underweight or recovering rabbits. Feeding adults alfalfa pellets long term can contribute to weight gain and bladder sludge. When in doubt, choose a plain timothy pellet and confirm with your vet.
Do pellets help wear down a rabbit's teeth?
Not really. The long, tough strands of grass hay are what grind a rabbit's molars during the sideways chewing motion that prevents painful spurs and malocclusion. Pellets are crushed and compressed, so they are eaten quickly with little of that grinding action. This is one big reason hay must dominate the diet. If you notice drooling, dropped food, or weight loss, see your exotic vet to check for dental disease.
Should I worry about pellets with seeds, nuts, or colorful pieces?
Yes, skip those muesli-style mixes. The colorful loops, seeds, and dried bits encourage selective feeding, where a rabbit picks out the sugary pieces and leaves the healthy ones, leading to imbalance and dental problems. Choose a uniform, timothy-based pellet so every bite is the same balanced formula. Plain and a little boring is exactly what a rabbit's digestive system wants.
What about water and fresh greens alongside hay and pellets?
Fresh water should always be available, and a daily handful of leafy greens like romaine, cilantro, and parsley rounds out the diet. The simple formula most exotic vets recommend is unlimited grass hay first, a measured portion of pellets second, a cup or two of safe greens, and treats only in tiny amounts. This keeps the gut moving and your rabbit happy. Introduce any new food slowly.
