Use the free tool at the top of this page first, then read the guide below to understand the result and use it well. Rabbit feeding confuses new owners because hay, pellets, and vegetables follow different rules, and getting the balance wrong causes weight gain or dental problems. This calculator turns your rabbit weight into daily portions: unlimited hay, a measured amount of pellets, and a daily vegetable portion, so the plate is right every day.
How to use it
Start by entering the numbers the tool asks for, using real measurements where you can, then press the calculate button and read the result box carefully. Check the result against common sense for your own setup, adjust one input at a time if the answer surprises you, and use the result as a daily plan rather than a one-off number.
Worked example
For example, a two kilogram rabbit gets about 40 grams of pellets and 300 grams of fresh vegetables per day, plus unlimited hay. A smaller one kilogram rabbit gets roughly half those measured portions, which shows why weight, not age alone, drives the numbers.
How the calculation works
The tool uses a simple, transparent rule based on the numbers you enter, so you can check the answer by hand if you ever doubt it. It does not guess, hide its working, or pretend to know more than the inputs allow, and that honesty is deliberate, because a pet care plan you can follow matters more than a complicated formula you cannot trust. If you change one input, such as weight, fish count, or tank size, the result moves in the direction you would expect, which is a good quick check that you typed the numbers correctly.
Why this matters
Hay matters most because it wears teeth down and keeps digestion moving, which is why it is unlimited while pellets are measured. Too many pellets crowd out hay, and too few vegetables miss out on variety, so a single clear daily plan beats guessing at every meal.
Keep the routine going
The best plan is the one you actually repeat, so tie the result to something you already do every day, such as the morning feed, the evening tidy, or the weekly shop. Keep the tool result visible for the first two weeks, note any day you miss, and do not restart from scratch after a missed day, because one missed day matters far less than giving up the routine entirely and starting again next month.
Three tips that help
Introduce new vegetables one at a time over several days, because a sudden mix can upset a sensitive rabbit stomach. Weigh pellets on kitchen scales at first, since a scoop or handful is easy to overfill without noticing. Offer hay in a rack and on the floor, because rabbits eat more hay when it is always within easy reach.
Common mistake to avoid
Never feed unlimited pellets to an adult rabbit, because measured pellets protect weight and keep hay as the main food.
Frequently asked question
How much should I feed my rabbit per day? Unlimited hay, about 20 grams of pellets per kilogram of body weight, and about 150 grams of vegetables per kilogram, as calculated here for your rabbit.
Put the result into practice
Save or print your result, put it where the person who feeds or cares for your animals will see it, and review it whenever weight, fish count, or tank setup changes. Small steady routines beat perfect plans that nobody follows, so keep the plan simple, repeat it daily, and adjust slowly when the numbers tell you something has changed.
