Fruit, carrots and commercial treats should not form a major part of everyday feeding.

This balance matters because rabbits are highly adapted herbivores. Fibre-rich food supports normal gastrointestinal function, while the prolonged chewing required for grass and hay contributes to normal dental wear.

Just as importantly, what a rabbit eats is valuable health information. A meaningful reduction in appetite, hay consumption or normal droppings can indicate illness and deserves prompt attention.

Ask someone to picture rabbit food and there is a good chance they will imagine:

a carrot.

Popular culture has been remarkably successful at creating that association.

Rabbit biology tells a different story.

A healthy rabbit’s diet is built primarily around something much less colourful:

grass and hay.

That is not simply because hay is low in calories or because rabbits happen to enjoy chewing it.

Rabbits have evolved around a diet of fibrous vegetation. Their digestive system, teeth and everyday feeding behaviour are all connected to that biology.

Understanding rabbit nutrition therefore requires moving away from the idea of:

“What should I put in my rabbit’s food bowl?”

towards a more useful question:

“How do I support the way a rabbit is designed to eat?”

Rabbits are not small dogs or cats

Rabbit nutrition should never be adapted from a dog or cat feeding model.

Dogs and cats commonly receive nutritionally complete food in measured meals.

Rabbits are herbivores with continuously growing teeth and a digestive system highly dependent on appropriate fibre intake.

They are also hindgut fermenters. Microorganisms in the caecum help process components of their plant-based diet, and rabbits produce specialised soft faecal material called caecotrophs, which they normally consume directly.

This process allows nutrients produced or released through caecal fermentation to be used by the rabbit.

You may rarely see normal caecotroph consumption because rabbits often eat them directly as they are produced.

That behaviour is:

normal.

It is not the rabbit eating ordinary faeces because something is wrong.

The digestive system is doing what it is designed to do.

Hay and grass should form the foundation of the diet

For most healthy adult rabbits, the central nutritional principle is straightforward:

Provide continuous access to appropriate grass or good-quality grass hay.

The UK's RSPCA describes the rabbit diet as being approximately 85% hay or grass, with roughly 10% leafy greens and herbs and around 5% pellets as a practical framework for healthy adult rabbits. These percentages are best understood as an illustrative feeding model rather than a mathematical prescription for every individual rabbit.

Hay supports two systems that are particularly important in rabbits:

the gastrointestinal tract and the teeth.

The fibre supports normal digestive function.

At the same time, eating fibrous grass and hay requires prolonged chewing movements that help wear the continuously growing teeth.

This means hay is not:

a snack.

And it is not:

bedding that the rabbit happens to eat.

It is the nutritional foundation.

What kind of hay should rabbits eat?

Healthy adult rabbits are commonly fed good-quality grass hays, such as timothy or other appropriate meadow and grass varieties.

The exact plants available vary geographically, so the Academy should avoid presenting one commercially familiar hay type as the only acceptable choice worldwide.

More important characteristics are that the hay is:

appropriate, clean, dry, palatable and free from obvious mould or contamination.

A rabbit should have enough available that they can browse throughout the day and night.

Hay should smell fresh rather than musty.

And because rabbits can be selective, guardians may need to experiment with appropriate varieties, cuts or presentation to encourage good hay consumption.

What matters most is not:

“Did I fill the hay rack?”

It is:

“Is my rabbit actually eating enough hay?”

Those are different questions.

Fresh grass can also be valuable

Appropriate fresh grass can form part of a healthy rabbit diet.

But fresh grass should be introduced sensibly if the rabbit is not accustomed to eating it.

And there is an important safety distinction:

Freshly cut or grazed grass is not the same thing as lawn-mower clippings.

The RSPCA advises against feeding lawn-mower clippings because chopped grass can ferment rapidly and become unsuitable to feed.

Grass also needs to come from an area where you are confident it has not been contaminated with:

unsafe chemicals, toxic plants or other hazards.

For rabbits with access to a garden or outdoor run, “natural” does not automatically mean:

safe to eat.

Why is fibre so important?

Rabbit digestion depends heavily on fibre.

Appropriate fibrous food helps maintain normal gastrointestinal motility and supports the complex microbial population within the hindgut.

But fibre also influences:

how long the rabbit spends eating.

A rabbit consuming grass and hay needs to:

select, bite and chew repeatedly.

That prolonged feeding behaviour is physiologically and behaviourally very different from rapidly consuming a bowl of concentrated food.

This is one reason why replacing large amounts of hay with pellets can create problems even when the rabbit still appears to be:

eating plenty.

The total volume of food disappearing is not enough information.

The type of food matters.

Rabbit teeth make diet particularly important

Rabbit teeth grow continuously.

Appropriate tooth wear depends heavily on normal chewing activity.

Fibrous grass and hay encourage prolonged side-to-side chewing and therefore play an important role in dental health.

This does not mean hay can prevent every dental problem. Tooth alignment, genetics, trauma and other factors can also contribute to dental disease.

But diet remains central.

A rabbit consuming mainly concentrated food may spend far less time performing the chewing behaviour associated with a natural fibrous diet.

So:

Rabbit dental care begins partly in the hay rack.

That does not replace veterinary dental assessment.

It helps support normal physiology between examinations.

What vegetables and leafy greens can rabbits eat?

A variety of appropriate leafy greens and herbs can complement the hay-based diet.

Suitable choices depend partly on availability and the individual rabbit, but commonly used examples can include leafy vegetables and culinary herbs such as certain lettuces, coriander/cilantro, basil, parsley and other rabbit-safe greens.

Variety can be useful because different plants provide different nutrients and sensory experiences.

But introducing a large amount of unfamiliar vegetation suddenly is not ideal.

New foods should generally be introduced:

gradually and individually enough that you can observe how the rabbit responds.

This is particularly useful when you are learning what a new rabbit normally eats.

The principle is:

variety within an appropriate diet — not unlimited variety for its own sake.

Are carrots good for rabbits?

Carrots are not poisonous to rabbits.

But they should not define the diet.

The root is relatively high in sugar compared with the leafy foods and fibrous grasses that should dominate rabbit nutrition.

That means carrot is better treated as:

a small occasional food

rather than:

the centre of the daily meal.

The leafy carrot tops may be used differently as an appropriate leafy green where safe and suitable.

The distinction matters because popular culture often teaches guardians precisely the opposite:

Rabbit = carrot.

A better nutritional association is:

Rabbit = hay and grass.

Can rabbits eat fruit?

Some fruits can be offered in small amounts, but they are generally higher in sugar and should be treated as:

occasional extras rather than dietary staples.

A piece of fruit does not become healthy simply because it is:

fresh and natural.

The same applies to many commercial rabbit treats containing ingredients such as:

honey, cereals, seeds, nuts or dried fruit.

A product being sold with a rabbit on the package does not automatically make it nutritionally appropriate as a regular part of the diet.

For most rabbits, the everyday diet should remain intentionally:

boring-looking compared with the treat aisle.

That is often a sign that it is closer to what their biology actually requires.

What role should pellets play?

Good-quality rabbit pellets can provide a convenient concentrated source of nutrients.

But for most healthy adult rabbits:

pellets should complement the fibrous diet, not replace it.

If a rabbit fills up on concentrated pellets, they may consume less hay.

That matters for:

digestive health, dental wear, calorie intake and feeding behaviour.

Pellet requirements vary with age, body condition, health, product formulation and other individual factors, so the amount should not be copied blindly from another rabbit.

Choose a product intended for rabbits and appropriate to the animal's life stage.

For many healthy adults, a plain, uniform pellet is preferable to colourful muesli-style mixtures that allow selective feeding.

Why can muesli-style rabbit foods be problematic?

Mixtures containing visibly different pieces allow rabbits to:

choose their favourite components and leave others behind.

That is known as selective feeding.

The rabbit may therefore consume a nutritional pattern quite different from the one the manufacturer intended.

Research supported by the UK's Rabbit Welfare Association & Fund and the University of Edinburgh has associated muesli-style diets with poorer outcomes including selective feeding and reduced hay consumption compared with more appropriate feeding patterns.

This illustrates an important principle:

What is offered is not necessarily what is eaten.

That applies across rabbit nutrition.

A bowl can contain an apparently balanced mixture while the rabbit systematically selects only certain components.

Rabbits need fresh water

Rabbits should have continuous access to fresh drinking water.

Water intake varies according to factors such as:

diet, temperature, body size, health and the amount of fresh vegetation consumed.

Both bowls and bottles are commonly used, but accessibility and cleanliness matter.

Many rabbits naturally drink well from a sturdy bowl, although individual circumstances and housing setup need to be considered.

The important outcome is:

reliable access to clean water that the rabbit can comfortably use.

And just like appetite:

a meaningful change in drinking behaviour can be health information.

What about young rabbits?

Young rabbits have different nutritional requirements from mature adults.

They are growing.

That means their diet cannot simply be copied from an adult rabbit feeding infographic.

The appropriate type and amount of hay, pellets and other foods may change as the rabbit develops, and recommendations can depend on age, growth, health and individual circumstances.

This is particularly relevant to more nutrient-dense forage such as alfalfa, which may have a role in growing rabbits but is generally not the default primary hay for healthy adult rabbits.

Rather than applying an arbitrary birthday-based switch, discuss your young rabbit's feeding plan with a rabbit-experienced veterinarian.

The principle is the same one we established for puppies and kittens:

Growth is a nutritional life stage.

But the diet must still be:

rabbit-specific.

Adult rabbits need a different balance

As growth slows, nutrition shifts towards maintaining:

healthy body condition, normal gastrointestinal function, dental health and appropriate activity.

For many healthy adults, this means the diet becomes strongly centred on:

grass and grass hay, with appropriate leafy greens and a comparatively small pellet component.

This is also the stage when excess concentrated food can contribute to:

unwanted weight gain.

An adult rabbit that eats pellets enthusiastically but largely ignores hay is not necessarily eating well simply because their appetite appears excellent.

What they choose to eat matters.

Senior rabbits should not automatically be put on a “senior diet”

Ageing does not produce one universal rabbit feeding prescription.

Some older rabbits remain healthy and maintain weight well.

Others may develop:

dental disease, arthritis, kidney disease, gastrointestinal problems or difficulty maintaining body condition.

An older rabbit losing weight should not simply be given more treats or concentrated food without asking:

Why is the weight changing?

The feeding plan should respond to:

the individual rabbit's health

rather than:

age alone.

Article 73, Senior Rabbit Care: Supporting Older Rabbits, will explore this in greater detail.

How do you know whether a rabbit is eating enough?

This is where rabbit nutrition becomes inseparable from rabbit health.

Guardians should learn what is normal for their individual rabbit.

That includes:

hay intake, interest in food, water intake, body weight and droppings.

A rabbit that normally attacks breakfast but suddenly leaves it untouched is communicating something.

A hay rack remaining unexpectedly full can matter.

So can:

smaller, fewer or absent droppings.

The combination is particularly important.

APPETITE + HAY INTAKE + DROPPINGS

should be treated as a connected rabbit health signal.

That is much more useful than a generic:

Food eaten ✓

Droppings are part of the nutrition record

Rabbit droppings can provide useful information about gastrointestinal function and food intake.

Guardians should become familiar with:

the normal size, quantity and appearance of their individual rabbit's faecal pellets.

A change does not automatically reveal the cause.

But a meaningful change can tell you:

something has changed.

This is especially important when droppings become:

significantly smaller, much less frequent or absent, particularly if the rabbit is also eating less or behaving differently.

Caecotrophs are different from ordinary faecal pellets and are normally re-ingested.

Finding excessive uneaten caecotrophs can sometimes indicate that the rabbit is unable or unwilling to consume them normally or that the diet or health status deserves review.

It should not simply be recorded as:

diarrhoea.

A rabbit that stops eating needs attention

Loss of appetite in a rabbit deserves a different response from:

“My dog skipped breakfast.”

Reduced food intake can be associated with gastrointestinal slowdown and may also be secondary to:

dental pain, other pain, illness, stress or an underlying obstruction.

A rabbit that stops eating or has a substantial reduction in appetite — particularly when accompanied by reduced or absent droppings, abdominal discomfort, lethargy or other changes — should receive prompt veterinary advice.

Do not simply wait:

until tomorrow to see whether they get hungry.

And do not assume the correct response is automatically:

syringe feeding.

If gastrointestinal obstruction is possible, professional assessment is important before blindly initiating assisted feeding.

This is one of the most important safety principles in the entire rabbit Academy cluster:

A rabbit that stops eating is not merely having a nutrition problem. They may be having a medical problem.

Should rabbits have their food changed gradually?

Yes, dietary changes should generally be introduced gradually.

The rabbit gastrointestinal system contains a complex microbial community adapted to the animal's existing diet.

Abruptly changing foods can disrupt digestive function.

This is particularly relevant when introducing:

new pellets, new greens or substantial changes in diet composition.

It does not mean guardians should avoid improving an inappropriate diet.

It means:

improve it thoughtfully.

If your rabbit currently eats a poor diet — for example, very little hay and a large quantity of concentrated food — a rabbit-experienced veterinarian can help you create a safer transition plan.

Can rabbits eat human food?

The fact that a rabbit willingly eats something does not mean they should.

Foods designed for humans such as:

biscuits, bread, chocolate, sweets and processed snacks

do not belong in a normal rabbit diet.

Some foods may be actively dangerous.

Others may simply displace the high-fibre nutrition rabbits actually need.

A rabbit begging for a piece of toast has demonstrated:

interest.

Not:

nutritional judgement.

That remains the guardian's responsibility.

Do rabbits need supplements?

Healthy rabbits eating an appropriate diet generally should not receive random vitamin or mineral supplements simply because:

“More nutrients must be healthier.”

As with every species, supplementation should have:

a specific reason.

That might be a veterinary recommendation related to a particular health or nutritional situation.

Routine supplementation should not be used as a substitute for correcting:

an inappropriate base diet.

No supplement can turn a low-hay, high-treat feeding pattern into good rabbit nutrition.

Body weight and body condition matter

Hay should be freely available, but that does not mean rabbits cannot become overweight.

Excess intake of energy-dense foods, limited activity and other factors can contribute to excessive body fat.

Weight alone also does not tell the complete story.

Breed and body size vary considerably, so an appropriate weight for one rabbit may be entirely inappropriate for another.

Monitoring should therefore combine:

weight trends + body condition + health + diet.

This is particularly valuable because thick fur can make gradual changes difficult to see.

A rabbit can look:

fluffy

without being:

appropriately conditioned.

Nutrition is also enrichment

Hay is food.

But hay can also support:

foraging, exploration and normal feeding behaviour.

Instead of providing every item in one bowl, suitable foods can sometimes be presented in ways that encourage rabbits to:

search, manipulate and forage.

Hay can be provided in multiple safe locations.

Appropriate herbs or greens can be distributed through the environment.

Pellets can sometimes be incorporated into safe enrichment rather than simply poured into a bowl.

This should never make it difficult to monitor whether the rabbit is eating.

But it recognises that:

feeding is something rabbits do — not merely something guardians administer.

Rabbits living together still need individual monitoring

Bonded rabbits often eat together.

That can make it difficult to know whether both animals are eating normally.

One rabbit may:

eat faster, dominate concentrated food or continue eating while their companion quietly reduces intake.

If:

the hay disappeared

you still do not necessarily know:

which rabbit ate it.

This becomes especially important if one rabbit:

loses weight, develops dental disease, becomes unwell or requires a modified diet.

The household may share feeding spaces.

The health record still belongs to:

the individual rabbit.

Key Facts

Grass and good-quality grass hay should form the foundation of the diet for most healthy adult rabbits and should generally be available freely.

The RSPCA uses an approximate adult feeding framework of 85% hay or grass, 10% appropriate leafy greens and herbs and 5% pellets.

Hay supports both normal gastrointestinal function and the prolonged chewing behaviour important for rabbit dental health.

Pellets complement the diet; they should not displace hay as the principal food for most healthy adult rabbits.

Fruit, carrots and many commercial treats should be limited rather than forming a major part of everyday nutrition.

Rabbits normally produce and consume caecotrophs as part of their digestive physiology.

Dietary changes should generally be introduced gradually.

Weight should be monitored as a trend and considered alongside body condition and food intake.

A significant reduction in appetite, hay intake or droppings can indicate illness and should not simply be treated as fussiness.

Rabbit nutrition should always be designed around rabbit biology — not adapted from dog or cat feeding.

When to Contact a Veterinarian

Contact a rabbit-experienced veterinarian if your rabbit develops a significant or persistent change in appetite, begins eating substantially less hay, loses weight unexpectedly, has difficulty chewing, repeatedly drops food, develops persistent uneaten caecotrophs, or shows a sustained change in normal droppings.

Seek prompt veterinary advice if your rabbit:

stops eating, produces substantially fewer or no droppings, becomes markedly lethargic, appears painful, develops a swollen or tense abdomen, repeatedly presses the abdomen to the ground or deteriorates rapidly.

Do not automatically assume every episode of reduced appetite is:

“GI stasis.”

Reduced gastrointestinal movement can be secondary to another problem, including pain, dental disease or potentially obstruction.

And do not automatically begin force or syringe feeding before obtaining appropriate advice if obstruction is possible.

The safest principle is:

When appetite and droppings change together, take the change seriously.

Frequently Asked Questions

What should rabbits eat every day?

For most healthy adult rabbits, grass or good-quality grass hay should form the majority of the diet and be available freely, accompanied by fresh water, appropriate leafy greens and a relatively small quantity of suitable pellets.

How much hay should a rabbit eat?

Rather than restricting hay to a fixed portion, healthy adult rabbits should generally have continuous access to appropriate grass hay. A practical comparison sometimes used is to offer at least a bundle approximately as large as the rabbit's body each day, while ensuring hay remains available rather than allowing the supply to run out.

Is timothy hay the only good hay for rabbits?

No. Timothy is a widely used grass hay, but other appropriate grass and meadow hays can also be suitable. Availability differs geographically. Quality, suitability and whether the rabbit actually eats the hay are more important than one universal variety.

Can rabbits eat grass?

Yes, appropriate fresh grass can form part of a healthy rabbit diet. Introduce it gradually if the rabbit is not accustomed to it and ensure it comes from a safe, uncontaminated area. Do not feed lawn-mower clippings.

Can rabbits eat carrots every day?

Carrot root is relatively high in sugar and is better offered in small amounts rather than forming a major everyday part of the diet. Rabbits should primarily be associated nutritionally with grass and hay, not carrots.

Can rabbits eat fruit?

Rabbit-safe fruit can generally be offered in small quantities as an occasional treat rather than a dietary staple because of its sugar content.

Do rabbits need pellets?

Pellets can provide useful concentrated nutrition, but for most healthy adult rabbits they should form a relatively small part of a diet based primarily on hay or grass. Individual requirements vary with age and health.

Is muesli rabbit food healthy?

Muesli-style mixtures can encourage selective feeding, where rabbits choose preferred pieces and leave others. This can distort nutrient intake and has also been associated with reduced hay consumption.

Do rabbits need vegetables?

Appropriate leafy greens and herbs can form a useful part of the diet alongside hay or grass. Introduce unfamiliar foods gradually and make sure each plant is safe for rabbits.

Can rabbits eat lettuce?

Some leafy lettuces can be included as part of an appropriate variety of greens. “Lettuce” covers many varieties, however, so guardians should check the specific plant rather than treating every lettuce as nutritionally identical.

Do rabbits need salt or mineral blocks?

Healthy rabbits receiving an appropriate balanced diet generally do not require arbitrary salt or mineral blocks. Ask your veterinarian before adding supplements.

Why does my rabbit eat its own droppings?

Rabbits normally produce nutrient-rich soft caecotrophs and consume them directly as part of normal digestion. These are different from the dry faecal pellets guardians commonly see in the litter area.

My rabbit is eating pellets but not hay. Is that okay?

It deserves attention. A rabbit may preferentially eat concentrated food while consuming too little hay. Because hay is important for gastrointestinal and dental health, investigate why hay intake is low and discuss persistent changes with a rabbit-experienced veterinarian.

My rabbit has stopped eating. Should I wait until tomorrow?

No. A significant reduction or complete loss of appetite in a rabbit can become serious and warrants prompt veterinary advice, particularly when droppings are also reduced or absent or the rabbit appears painful or lethargic.

Should I syringe-feed a rabbit that is not eating?

Not automatically. Assisted feeding can be useful in appropriate circumstances, but reduced appetite may have different causes, and gastrointestinal obstruction needs consideration. Seek rabbit-experienced veterinary advice rather than assuming syringe feeding is always the correct first response.
