How much food does a rabbit need?
A healthy adult rabbit's diet is built around one simple ratio: the large majority should be good-quality hay or fresh grass, available essentially all the time, with a small measured portion of nuggets and a daily helping of fresh leafy greens making up the rest. Getting this balance right matters more for a rabbit's health than almost any other aspect of their care.
Hay is the foundation, not a side item
Rabbits are grazing animals, and their digestive system is built to process a near-constant supply of fibrous plant material. Hay or fresh grass should be available essentially all day, every day, and should make up the large majority of what a rabbit eats — far more than the nuggets, which are easy to over-focus on simply because they look like the main meal.
A rabbit that is not eating enough hay is at real risk of dental problems, since their teeth grow continuously and rely on the chewing action of fibrous food to wear down naturally, as well as digestive issues from too little fibre.
Nuggets: a small, measured amount
The Rabbit Welfare Association recommends a small, measured portion of nuggets — commonly described as roughly an egg-cup sized amount per kilogram of your rabbit's bodyweight — rather than free access, since nuggets are more calorie-dense than hay and rabbits will readily overeat them if left available all day. Measuring the portion, rather than judging it by eye, is the more reliable way to keep this in check.
Muesli-style mixes are generally discouraged compared with a uniform nugget, because rabbits can selectively eat the tastier pieces and leave the rest, leading to an unbalanced diet even when the bag itself is nutritionally complete.
Fresh greens, and getting the balance right
A daily portion of fresh, rabbit-safe leafy greens adds variety and additional nutrients, introduced gradually if your rabbit is not used to them, since a sudden large amount of new fresh food can upset their digestion. The exact amount that suits your individual rabbit depends on their size, age and health, so this is a general guide rather than a fixed feeding plan, and your vet is the right person to advise if you are concerned about your rabbit's weight or diet.
Fresh water should always be available alongside all of this, checked and changed daily whether it comes from a bottle or a bowl.

Common questions
- How much hay should a rabbit eat each day?
- Hay or fresh grass should make up the large majority of a rabbit's daily diet and be available essentially all the time, rather than being measured out as a fixed amount, since rabbits need near-constant access to fibrous food.
- Can rabbits eat too many nuggets?
- Yes, nuggets are more calorie-dense than hay, and rabbits will readily overeat them if given free access. A small, measured daily portion rather than an unlimited bowl is the recommended approach.
- Is muesli-style rabbit food bad?
- It is generally discouraged compared with a uniform nugget, because rabbits can pick out the tastier pieces and leave the rest, which can lead to an unbalanced diet even from a nutritionally complete bag.
- What fresh vegetables can rabbits eat daily?
- A range of rabbit-safe leafy greens can be offered daily in modest amounts, introduced gradually to avoid digestive upset. Your vet or a rabbit welfare organisation can advise on specific safe options for your rabbit.
