    A rabbit's daily menu, sized to its weight

    Type the weight of your rabbit, pick its age, and the rabbit food calculator lays out the whole day: pellets in tablespoons and cups, chopped vegetables, the cap on carrots and fruit, and how much water a rabbit that size drinks. Hay never gets a number, because it should never run out. Add the weight of one cup of your pellets and you also get the monthly amount in pounds.

    1/4 cup
    pellets per 6 lb of rabbit a day, adult
    2 cups
    chopped vegetables per 6 lb, at least
    120 mL
    water per kilogram of rabbit a day

    Six boxes, two of them optional

    1. Weight - from a kitchen scale is best. Hold the rabbit on a bathroom scale and subtract your own weight if it will not sit still on a small one.
    2. Unit - pounds or kilograms. Every result is still printed in cups, tablespoons and fluid ounces.
    3. Age - six stages from the House Rabbit Society schedule. Under 7 months pellets are free-fed, from 7 months they are measured.
    4. Body condition - optional. Overweight keeps the pellets at the low end, underweight widens the range upward. It only applies from 1 year.
    5. Number of rabbits - optional, for a bonded pair or a group of similar weight. The daily table stays per rabbit, the totals scale.
    6. Weight of one cup of pellets - optional, in ounces. Weigh one level cup of your brand once and the monthly supply comes out in pounds.

    The four food groups, mapped

    Rabbit diets in the US are built on a short set of rules from the House Rabbit Society, the rescue and education group whose diet page most rabbit vets point owners to, with the Merck Veterinary Manual giving a second figure for pellets and the reference value for water. Each food group has its own role and its own limit:

    Grass hay
    Unlimited, every day. Timothy, orchard and oat hay for adults. Keeps the gut moving and grinds down teeth that never stop growing.
    Leafy greens
    About 75% of the fresh food. At least three kinds a day, washed. Romaine, cilantro, dandelion greens, kale, bok choy.
    Non-leafy vegetables and fruit
    Non-leafy up to 1 tbsp per 2 lb (about 15%), fruit up to 1 tsp per 2 lb (no more than 10%). Carrots belong here.
    Pellets
    Measured from 7 months. 1/4 cup per 6 lb (House Rabbit Society) up to 1/4 cup per 5 lb (Merck). Plain, timothy-based, 18% fiber or more.

    Two things fall outside the map on purpose. Hay has no quantity, so the calculator never prints one. And treats beyond fruit, such as yogurt drops or pellet mixes with seeds and corn, are not part of the plan at all; the House Rabbit Society advises against pellets with those mixed in.

    How much to feed a rabbit by weight

    This is the adult column of the calculator for eight body weights, one rabbit, no body condition chosen. Pellets show the range from the House Rabbit Society figure to the Merck figure; vegetables are the minimum, non-leafy vegetables and fruit are caps.

    Rabbit weight Pellets a day Vegetables, at least Non-leafy, up to Fruit, up to Water
    2 lb (0.91 kg)1.3 to 1.6 tbsp0.67 cup1.0 tbsp1.0 tsp3.7 fl oz
    3 lb (1.36 kg)2.0 to 2.4 tbsp1.00 cup1.5 tbsp1.5 tsp5.5 fl oz
    4 lb (1.81 kg)2.7 to 3.2 tbsp1.33 cups2.0 tbsp2.0 tsp7.4 fl oz
    6 lb (2.72 kg)4.0 to 4.8 tbsp2.00 cups3.0 tbsp3.0 tsp11.0 fl oz
    8 lb (3.63 kg)5.3 to 6.4 tbsp2.67 cups4.0 tbsp4.0 tsp14.7 fl oz
    10 lb (4.54 kg)6.7 to 8.0 tbsp3.33 cups5.0 tbsp5.0 tsp18.4 fl oz
    12 lb (5.44 kg)8.0 to 9.6 tbsp4.00 cups6.0 tbsp6.0 tsp22.1 fl oz
    15 lb (6.80 kg)10.0 to 12.0 tbsp5.00 cups7.5 tbsp7.5 tsp27.6 fl oz

    A cup holds 16 tablespoons, so 4.0 to 4.8 tbsp for a 6 lb rabbit is 0.25 to 0.30 cup. Most owners find a tablespoon easier to level than a quarter cup, which is why the result leads with it.

    Six life stages, six feeding rules

    The age box changes more than the numbers. Below 7 months the question is not how much pellet, but which foods are on the menu at all. This is the House Rabbit Society schedule the calculator follows:

    Age Pellets Hay Vegetables and fruit
    Under 7 weeksnibbles from 3 weeks, open access from 4 weeksalfalfa, same timingnone, mother's milk is the main food
    7 to 12 weeksunlimitedunlimitednone yet
    12 weeks to 7 monthsunlimitedunlimitedone new vegetable at a time, under 1/2 oz
    7 months to 1 year1/2 cup per 6 lbswitch to grass hays, less alfalfabuild up gradually
    1 to 5 years1/4 cup per 6 lb (to 1/4 cup per 5 lb)unlimited grass hayat least 2 cups per 6 lb
    6 years and olderadult amount while weight holds; frail rabbits may need moreunlimited grass hayas for adults

    The jump from unlimited pellets to a measured portion at 7 months is the single biggest change in a rabbit's diet. A 4 lb young adult drops to 5.3 tbsp a day, and a year later, at the adult rate, to 2.7 to 3.2 tbsp. Hay fills the gap.

    Five rabbits run through the calculator

    6 lb adult, condition not chosen
    Pellets 4.0 to 4.8 tbsp, vegetables at least 2.00 cups, non-leafy up to 3.0 tbsp, fruit up to 3.0 tsp, water about 11.0 fl oz. Pellets for 30 days: 8.3 cups.
    2.5 kg adult, overweight
    That is 5.51 lb. Pellets fixed at the low rate, 3.7 tbsp or 0.23 cup; hay and vegetables unchanged. A target weight is a job for the vet.
    4 lb, 9 months old
    Young adult rate, 5.3 tbsp or 0.33 cup of pellets, with a note to move from alfalfa to timothy over several weeks.
    Bonded pair, 6 lb each, 4.2 oz cup
    16.5 cups of pellets for 30 days, which at 4.2 oz per cup is 4.33 lb. A 5 lb bag lasts a little over a month.
    5 lb senior, underweight
    No measured portion: free-fed pellets under veterinary guidance, as House Rabbit Society suggests for frail older rabbits, and a dental check first.

    What the numbers say once they sit side by side

    Everything scales in a straight line with weight. A 12 lb rabbit gets exactly twice what a 6 lb rabbit gets, from pellets to water, so there is no special rule for dwarf or giant breeds; the scale does the work.

    The pellet range is narrow. The two published figures, 1/4 cup per 6 lb and 1/4 cup per 5 lb, differ by only 20%, less than one tablespoon for a 6 lb rabbit. Choosing a body condition matters more than which source you trust.

    Water is easy to underestimate. A 6 lb rabbit drinks about 327 mL a day at Merck's 120 mL per kg, close to 1.4 cups, which Merck notes is about double what a dog or cat of the same size is usually estimated to drink. Rabbits on lots of wet greens drink less from the bowl, so the figure is a reference, not a target to force.

    Rabbit feeding questions, answered with numbers

    How much should a rabbit eat a day?
    As much grass hay as it wants, plus a measured part of the rest. For a 6 lb adult that is 4.0 to 4.8 tbsp of pellets, at least 2.00 cups of chopped vegetables with up to 3.0 tbsp non-leafy, up to 3.0 tsp of fruit, and about 11.0 fl oz of water.
    How much pellets to feed a rabbit per pound?
    For adults, House Rabbit Society gives 1/4 cup per 6 lb, which is about 0.67 tbsp per pound; Merck gives 1/4 cup per 5 lb, 0.8 tbsp per pound. Young adults from 7 months to 1 year get 1/2 cup per 6 lb.
    How much hay does a rabbit need per day?
    There is no measured amount: hay should be available all the time, and a rabbit that stops eating hay needs a vet. That is why the calculator prints "unlimited" instead of a weight. Alfalfa hay is for young and nursing rabbits; adults get timothy, orchard or oat hay.
    How much pellets to feed a baby rabbit?
    From 7 weeks to 7 months, as much as it eats, along with unlimited hay. Measuring starts at 7 months, at 1/2 cup per 6 lb. Before 7 weeks a kit lives mainly on its mother's milk and only nibbles pellets and alfalfa.
    How many grams of food does a rabbit eat per day?
    It depends on the pellets, because a cup of one brand can weigh noticeably more than a cup of another. Weigh one level cup of yours and enter it in ounces; the calculator then gives the monthly total in pounds. Hay is not counted, because it is not rationed.
    How much lettuce should a rabbit eat?
    Romaine and red or green leaf lettuce count as leafy greens, part of the 2 cups per 6 lb. House Rabbit Society asks for at least three kinds of greens a day, so lettuce should share the bowl with others rather than fill it.
