Rabbit Feeding: Schedule, Diet, and Why They Stop Eating

A rabbit's gut depends on constant food throughput the same way a guinea pig's does, which is exactly why a skipped meal deserves same-day attention here, not a wait-and-see approach.

Feeding Schedule by Life Stage

• Nursing kits (birth to about 7 weeks): Mother's milk only at first, notably just once or rarely twice a day for 2 to 10 minutes per session, rabbit milk is unusually rich, so kits can go roughly a day between feedings. Weaned by around 8 weeks.
• Transition (3 to 7 weeks): Alfalfa hay and alfalfa-based pellets introduced with free-choice access alongside nursing. New greens typically start around 12 weeks in small amounts.
• Juveniles (7 weeks to about 6 months): Unlimited alfalfa hay and alfalfa-based pellets, the extra calories and calcium support growth. Vegetables added gradually from about 3 months, one new item at a time.
• Transition to adult (roughly 4 to 7 months, overlapping the end of the juvenile stage): Alfalfa is phased out in favor of grass hays, and pellet portions are gradually reduced over several weeks as unlimited grass hay takes over as the diet base.
• Adults (7 months to about 6 years): Unlimited grass hay as 80 to 85% of the diet. Measured pellets, roughly 1/8 to 1/4 cup of high-fiber, timothy-based pellets per 5 to 6 lbs of body weight daily, sources vary on the exact ratio. Vegetables, roughly 1 to 4 cups per several pounds of body weight depending on the source, at least 3 varieties of leafy greens. Fruit and treats stay capped low, roughly 1 to 2 tablespoons once or twice a week, not daily.
• Seniors (about 6 years and up): Unlimited grass hay continues, alfalfa may be reintroduced if the rabbit is underweight, with a higher treat allowance and more individualized, vet-guided feeding.

Fresh water needs to be available at all times, by bottle or bowl, at every stage.

Portions for Large and Giant Breeds

Pellets and vegetables are measured against body weight, which matters more than usual in a species that runs from about 2.5 pounds to over 20. At about 1/4 cup of pellets and at least 2 cups of chopped vegetables per 6 pounds a day, the numbers work out like this:

Giants such as the Flemish are prone to obesity, so hold them at the lower end of the pellet range and let hay make up the difference. Hay stays unlimited at every size, and a giant goes through it far faster, so buy it by the box. Water needs climb with body weight the same way, so a giant needs a big, heavy bowl that gets checked and refilled more than once a day.

What Rabbits Eat

Unlimited grass hay is the foundation of an adult rabbit's diet at every stage, available 24/7. Alfalfa hay is richer and reserved for babies, juveniles, pregnant or nursing does, and underweight seniors, not healthy adults, the extra calcium and calories can contribute to obesity and bladder sludge.

Pellets should be a fresh, high-fiber, plain timothy-based pellet, not colorful mixes with seeds, nuts, or dried fruit, which are linked to obesity and dental disease. Pellets are measured for adults, not free-fed the way hay is.

Vegetables should be fresh leafy greens as the bulk of the fresh portion, romaine, cilantro, parsley, basil, arugula, bok choy, and carrot tops, with at least 3 varieties offered daily and new items introduced one at a time to watch for soft stool. Non-leafy vegetables like bell pepper, cucumber, and carrots go in smaller, more limited amounts, they're higher in sugar and starch than their reputation suggests. Fruit is purely a treat, fed a couple times a week at most.

There's no gut-loading or calcium dusting here, that's a reptile practice. The closest equivalent is gradual diet transitions, sudden changes to hay, pellet brand, or vegetables can disrupt the cecal gut flora and trigger soft stool or GI stasis.

Water

A rabbit drinks about 120 mL per kilogram of body weight a day, roughly twice what a dog or cat of the same size drinks. A 6 lb (2.7 kg) rabbit takes about 11 fluid ounces (325 mL). Rabbits drink significantly more from an open bowl than from a sipper bottle, so a heavy, flat-bottomed bowl is the better default. A rabbit that gets a sore, damp chin from a bowl does better with a bottle, and since rabbits chew the valve of a bottle, a stainless steel one lasts longest. Whichever you use, change the water every day, and wash a bowl rather than topping it up.

Safe Treats and Foods to Avoid

Safe in small amounts: fresh parsley, cilantro, basil, and mint, small pieces of apple, banana, strawberry, or blueberry, and limited bell pepper, cucumber, or carrot.

Toxic, never feed: avocado (can cause respiratory distress and fatal heart failure), chocolate, onions, garlic, and chives (can cause hemolytic anemia), and rhubarb (high oxalic acid, linked to kidney damage). Iceberg lettuce isn't toxic but has near-empty nutritional value and can cause digestive upset in quantity. Skip processed human foods sometimes mistaken for treats too, bread, crackers, cereal, and especially yogurt drops, which are explicitly flagged as inappropriate despite being sold commercially as rabbit treats.

Growth, Weight, and Body Condition

Rabbits reach sexual maturity at about 3.5 to 4 months in small breeds such as the Polish Dwarf and the Dutch, 4 to 4.5 months in medium breeds, and 6 to 9 months in giants, so the timing of a spay or neuter follows breed size more than the calendar. Rabbits pick the richest parts of a meal and leave the fiber, which is why they gain weight easily on pellets, fruit, and treats.

Weigh a rabbit once a week on a kitchen scale that reads in grams, and write the number down. A change in weight is often the first sign of illness, and a slow drift is easy to miss by eye. Once a month, feel the body as well, because a thick coat hides fat. Body condition is scored on a 9-point scale, and 4 to 5 is the usual ideal for an adult.

A home score is an estimate. Anything outside 4 to 5, or any doubt, is a question for a rabbit-experienced vet before the diet changes, and weight alone cannot show whether a change is fat or muscle. Make any weight change gradual, and never cut food to the point a rabbit stops eating: that is the stasis emergency described in the GI stasis guide.

Why Rabbits Stop Eating

1. GI stasis. A slowdown or stoppage of normal gut motility, one of the most common life-threatening emergencies in pet rabbits. Often the downstream result of low fiber, dehydration, pain, or stress, and self-perpetuating once it starts.
2. Dental disease. Rabbit teeth grow continuously, and overgrown teeth or spurs can cut the mouth or make chewing painful, one of the most frequent underlying causes of appetite loss, and one that can develop silently. Our guide on why rabbits need unlimited hay covers how quickly those teeth overgrow once the fiber runs short.
3. Stress. New housing, a new pet in the household, loud noises, or handling changes are real triggers, even when the cause seems minor to an owner.
4. An abrupt diet change. Switching hay, pellet brand, or vegetables too quickly can disrupt cecal bacteria balance and cause reduced eating or soft stool.
5. Pain from an unrelated illness. Urinary tract disease, gas, respiratory infection, or reproductive disease can all cause secondary appetite loss.
6. Fur ingestion during a heavy molt. Swallowed fur combined with dehydrated gut contents can form a hard-to-pass mass. Regular brushing during molts helps prevent it.
7. Certain medications. Some drugs used to treat other conditions can themselves slow gut motility as a side effect.

When to Worry

Because rabbits are obligate continuous grazers, any noticeable drop in eating or fecal output is treated as urgent, not something to wait out. The alarm point is 8 to 12 hours without food or droppings. Past eight hours it is abnormal and a vet should see the rabbit, and at twelve it is an emergency, so eight is when you make the call and twelve is when you are already late. Fasting beyond about 24 hours risks fatty liver disease. Don't wait through a full day hoping it resolves, same-day vet contact is the safe default the moment a rabbit skips a meal or stops producing normal droppings.

Warning signs that make it more urgent regardless of the exact hour count: no fecal pellets at all, or pellets that are small, misshapen, or strung together with mucus, a hunched or tense posture, audible tooth grinding, a bloated or tense abdomen, lethargy, drooling, and reduced water intake. About 70% of rabbits survive GI stasis, and most uncomplicated cases resolve with veterinary treatment over three to five days, but delayed cases can require days of hospitalization, so early intervention matters here.
