The short answer
Iceberg lettuce is not a useful staple because it is mostly water and provides less nutrition than darker leafy varieties.
Recommended amount
Prefer romaine, green leaf, red leaf or other established leafy greens. If a small amount is eaten, monitor normally unless symptoms occur.
Suitable rabbit age
Introduce fresh foods gradually only after a young rabbit is established on hay and appropriate pellets—commonly around 12 weeks. Ask a rabbit-experienced veterinarian about younger, elderly, ill, pregnant or nursing rabbits.
Preparation
Identify the plant correctly. Wash thoroughly, remove soil and chemical residue, drain, and serve raw and plain. Introduce only one new food at a time.
Parts or forms to avoid
Avoid large servings, especially for a rabbit not accustomed to fresh greens.
Nutritional and feeding notes
This classification reflects poor dietary value rather than treating a small bite as a poison.
This guide is general educational information, not a diagnosis or individual feeding prescription. Plant composition, contamination and a rabbit’s health vary. If your rabbit has eaten something questionable, stops eating, produces fewer droppings, appears painful or becomes unwell, contact a rabbit-experienced veterinarian promptly.
