Best Calcium-Rich Foods for Domestic Rabbits

Ranked by calcium content among foods safe for domestic rabbits in the Creature Feast catalog.

Timothy Hay per 100g: approximately 400-600mg calcium Timothy hay provides moderate calcium at 0.4-0.6%, which is the ideal baseline for adult rabbits. Because it is the bulk of the diet, it is actually the largest single source of calcium by volume.

Romaine Lettuce per 100g: approximately 33mg calcium Romaine lettuce is a low-calcium green (about 33mg per 100g) that makes an excellent daily staple. It contributes some calcium without overloading the system — perfect for the rabbit's unique absorption physiology.

Endive per 100g: approximately 52mg calcium Endive provides moderate calcium and is a great daily green. Its calcium content is moderate enough for regular feeding without the risks associated with high-calcium greens.

Cilantro per 100g: approximately 67mg calcium Cilantro offers moderate calcium and can be rotated into the daily greens mix. Most rabbits enjoy its distinctive flavor.

Watercress per 100g: approximately 120mg calcium Watercress provides moderate calcium alongside many other nutrients. A good rotation green that adds variety without excessive calcium.

Dandelion greens per 100g: approximately 187mg calcium Dandelion greens are moderately high in calcium (about 187mg per 100g). Excellent nutrition overall but should be rotated with lower-calcium greens rather than fed as the sole daily green.

Parsley per 100g: approximately 138mg calcium Parsley is high in calcium (about 138mg per 100g) and should be offered in small amounts as part of a rotation, not as a daily staple, to avoid calcium overload.

Kale per 100g: approximately 150mg calcium Kale is calcium-rich (about 150mg per 100g) and nutritious but should be fed in moderation due to your rabbit's total calcium absorption. Use as an occasional rotational green, not a daily staple.

Alfalfa Hay per 100g: approximately 1,500mg calcium Alfalfa hay is very high in calcium (about 1.5%) and should only be fed to growing kits and pregnant or nursing does. For adult rabbits, it contributes too much calcium for their absorb-everything physiology.

#10

Bok Choy per 100g: approximately 105mg calcium Bok choy provides moderate calcium (about 105mg per 100g) and is well tolerated. A good rotational green for variety.
