How much hay should the rabbit eat each day?

Grass hay should be available at all times and make up the largest part of the diet, with no imposed limit: a healthy rabbit eats it continuously. The practical reference is not a precise dose but a behaviour, that the rabbit always has fresh hay in front of it and chews it for much of the day. If it eats little, the first suspicion is that it is too full of pellets, and it is worth reducing those.

Can I give fruit and carrots every day?

Better not to. Fruit and sweet roots like carrots are rich in sugar and starch and are not part of the daily ration, but a rare treat in small portions. They are not poisonous, but given often they shift the balance towards sugars the rabbit does not handle well, encouraging gut imbalances and weight gain. The everyday diet is hay and leafy greens, not fruit.

Are colourful pellets with seeds and flakes fine?

That is the type to avoid. In mixes with seeds, cereals and coloured pieces the rabbit picks the sweeter, more palatable parts and leaves the rest, and this selective feeding creates deficiencies and excesses at the same time. A uniform high fibre pellet, the same in every piece, is preferable because it leaves no room to choose and keeps the ration consistent. The amount should still be kept controlled.

How do I introduce a new vegetable safely?

One at a time and in small amount. Add a single new food, in a small portion, and wait a few days watching the stools and appetite before introducing another. That way, if something upsets digestion, you can identify it for certain. An abrupt change or too many new foods together can alter the gut flora and trigger a slowdown, which in a rabbit should always be taken seriously.

Build a hay and vegetable diet for your rabbit

How to build a rabbit's daily diet: hay always available, leafy greens, limited pellets, and the digestive signals that call for an exotics vet.

Audience: Pet owners
Species: Rabbit
Scope: Valid everywhere

What you need before you start

Fieno di erba di buona qualità sempre disponibile, verde, profumato e non polveroso o ammuffito

Most of a pet rabbit's health problems start at the food bowl. It is a herbivore with teeth that grow for life and a gut that needs fibre moving through it constantly, and when the diet tips towards pellets or sugary snacks the consequences arrive on two fronts: teeth that do not wear down enough and a digestive system that slows until it stops. The basic rule is easy to state and hard to respect, because it goes against the common idea that pellets are the meal and hay a side dish: in a rabbit it is exactly the reverse. Hay is the base of the diet, leafy greens are the daily addition, pellets are a small controlled share, and sugary snacks are a rare exception. This guide covers how to build the ration, which greens to choose and introduce gradually, and which digestive signals mean you should contact an exotics vet at once.

Hay is the base, not a side dish

Grass hay must be available at all times, day and night, and makes up the largest part of what the rabbit eats. It does two things together: fibre keeps the gut moving and prolonged chewing wears down the teeth, which otherwise grow abnormally. A rabbit that eats little hay because it is full of pellets is a rabbit at risk, even if it looks well.

Quality matters as much as quantity. Good hay is green, smells of grass, is dry and free of dust and mould. Keep it in an airy place and change it often, because a rabbit refuses stale hay and eating less of it means chewing less. Placing it in several spots in the enclosure, including near the litter tray where the rabbit likes to sit, increases how much it eats on its own.

Leafy greens: which and how much

Fresh leafy greens are the daily addition to hay and bring water, variety and micronutrients. They should be offered every day, washed and dry, favouring a mix of several types rather than a single vegetable in large amount. Variety lowers the risk of excesses and makes the ration more like what a herbivore finds in nature.

How to place fresh foods in the rabbit's day
Group	Role in the diet	Practical caution
Suitable herbs and garden leaves	Base of the daily greens, mixed	Introduce one type at a time and watch the stools
Watery, less nutritious vegetables	In small part, for variety	Not the only fresh food, they bring little fibre
Starchy or sugary parts	Only occasional, in tiny portions	Roots and sweet fruit must be limited heavily
Unidentified or uncertain wild plants	Avoid until they are certain	Some common plants are toxic to the rabbit

Fruit and vegetables rich in sugar or starch, such as sweet roots and fruits, are not a daily food but a rare treat in small portions. Not because they are poisonous, but because they shift the balance towards sugars the rabbit is not built to receive in quantity, encouraging imbalances of the gut flora. Plants gathered outdoors are offered only if their species and origin are known for certain, because several ornamental and wild plants are toxic.

Pellets and what to limit

Pellets are not the main meal but a supplement in controlled amount. A common mistake is to leave them available without limit: the rabbit, finding them more palatable than hay, tends to fill up on pellets and neglect the hay, with the consequences already seen on teeth and gut. The right share depends on the individual animal's weight, age and condition, and is one of the points where it is worth getting a reference from the vet.

Prefer a uniform high fibre pellet over colourful mixes with seeds, cereals and sweet parts.
Mixes where the rabbit can pick out pieces encourage selective and unbalanced feeding.
Shop bought sugary snacks, biscuits and honey sticks are a rare exception, not a daily treat.
Bread, puffed cereals, dairy and foods for other species are not part of a rabbit's diet.
If the rabbit gains weight or snubs the hay, the first move is to reduce pellets, not increase them.

Building the daily ration step by step

Always start from available hay
Make sure there is fresh, clean hay at all times, in several spots in the enclosure. It is the base that must stay constant regardless of the rest.
Offer leafy greens every day
Prepare a mix of several suitable types, washed and dried. Variety matters more than the amount of any single vegetable, and lowers the risk of excesses.
Measure the pellets rather than leaving them free
Give a controlled share based on the rabbit's weight and condition, without topping up the bowl when it empties. If you need a reference, ask the vet.
Introduce each new food one at a time
Add a single new food at a time and in small amount, waiting a few days before the next. That way, if something upsets digestion, you know what it was.
Always ensure clean water
Fresh water must be available at all times and checked every day, because a fibre rich diet needs plenty of it and a drop in intake is a signal.
Watch the stools and the appetite
Check every day that the droppings are plentiful and regular and that the rabbit eats steadily. A drop in droppings or appetite is an early alarm not to ignore.
Record intake and changes
Note how much hay it eats, what it eats and how the stools look. The log makes visible a gradual change that memory would miss.

Changes, digestive signals and when to worry

The rabbit's digestive system does not tolerate abrupt changes. Every switch, from the type of hay to the pellets to a new vegetable, should be made gradually over days, watching the stools at each step. A sudden change can alter the gut flora and trigger a dangerous slowdown, which in a rabbit worsens quickly.

A drop in or absence of droppings, or droppings much smaller than usual: an early sign of gut slowdown.
Refusal of food and hay for some hours: in a rabbit loss of appetite is always an emergency, not a whim.
A hunched posture, stillness, teeth grinding from pain, a tense abdomen.
Soft stools, diarrhoea, or many uneaten cecotropes stuck to the fur.
Drooling, difficulty chewing or weight loss, which can point to a dental problem.

What to do next

Build the diet from grass hay always available, add a mix of leafy greens every day, and keep pellets to a measured share rather than free, avoiding colourful mixes and sugary snacks. Introduce each new food one at a time while watching the stools, always ensure clean water, and record intake and appetite. Remember that a rabbit which stops eating or passing droppings for some hours is an emergency to take to an exotics vet at once.
