Diet Portion Calculator For Rabbits

Use this tool to determine the proper amount and portion of food to give to your rabbits based on their age and weight.



Young Rabbits.

Starting at 7 weeks, rabbits can start eating solid foods like pellets and hay. But, you should wait until 12 weeks old before giving vegetables. Feed your rabbits high-quality alfalfa hay and pellets. You can let your rabbits decide how much pellets and hay they want to eat during this time period to maximize growth.

Finally, when feeding veggies to your rabbits at 12 weeks, start SLOWLY and ONE vegetable at a time to ensure that your rabbits wouldn’t develop digestive problems. Rabbits this young are more susceptible to digestive problems.


Teenage Rabbits

Starting at 7 months, you can start changing your rabbit’s diet SLOWLY. Introduce grass hay while slowly decreasing alfalfa hay. Increase the amount of vegetables from 15 grams per day up to 128 grams per day GRADUALLY. Pellets should be decreased from unlimited amounts to ½ cup per 6 lbs (2.7 kg) of body weight. Treats should be given 1-2 times per week in small amounts.


Adult Rabbits

You can choose between grass, oat, or straw hay to feed your rabbits. Let them decide how much hay they want to eat during this time. Just make sure that it’s not alfalfa because it’s too high in calcium. Pellets should be controlled to ½ cup per 6 lbs (2.7 kg) of BW. While vegetables should be fed 1-2 cups per 6 lbs (2.7kg) of BW. Treats should be kept to a minimum or 1-2 times per week in small amounts.


Senior Rabbits

Old rabbits can be fed alfalfa hay if they are frail and weak. The extra calcium in alfalfa can help. But, a safer move is to bring your rabbit to a veterinarian and let them decide your rabbit’s diet. Old rabbits needs to be monitored closely and a case-by-case basis.

All of the things I’ve written above assumes that your rabbit is healthy and normal. The portions of their diet would change depending on the situation. For example, rabbits that are pregnant would need to eat more. Always consult your veterinarian.
