Rabbit Health
Can Rabbits Eat Lettuce UK?
Quick answer
**Lettuce is not ideal rabbit food.** Iceberg lettuce is best avoided — low nutrition and diarrhoea risk. Darker leaves like romaine are acceptable in small amounts alongside better greens. **Unlimited hay must always come first.** Never let lettuce replace hay — that risks [gut stasis](/glossary/rabbit-gi-stasis).
Key takeaways
- Small amounts of darker lettuce varieties (romaine, lamb's lettuce) are usually fine as part of a varied green portion. Iceberg lettuce is best avoided — it is low in nutrients and can cause diarrhoea.
- Iceberg lettuce is not recommended. It contains mostly water with minimal nutritional value and can cause loose stools in rabbits. It must never replace hay.
- Safe daily greens include coriander, parsley, kale, spinach (in moderation), and romaine lettuce. Introduce new greens gradually. Unlimited hay remains the dietary foundation.
