Why
Dark leaf lettuces are standard rabbit greens. The House Rabbit Society lists romaine and red or green leaf lettuce among its leafy greens, the RSPCA names romaine among good greens to feed daily, and Pasadena Humane lists romaine, green leaf and red leaf lettuce among vegetables that can be fed daily.
Iceberg lettuce is the exception. The Royal Veterinary College lists romaine lettuce but not iceberg or light colored leaves, and the RSPCA, VCA Animal Hospitals and Pasadena Humane all put iceberg on their avoid lists. Rabbit.org explains that iceberg is not toxic, but it is low in nutrients and higher in water than darker lettuces, and large amounts can cause diarrhea.
What to watch out for
- Iceberg and other pale head lettuces
- Lettuce as the only green, instead of one of several
- Wilted, slimy or spoiled leaves
- Bagged salad mixes that include onion, unknown leaves or dressing
- Soft droppings after a new type of lettuce
How to serve it
- Wash the leaves well, then serve them still damp.
- Tear a few leaves of romaine or leaf lettuce into the bowl.
- Mix the lettuce with at least two other leafy greens or herbs.
- Rotate lettuces and other greens through the week for variety.
- Introduce a new lettuce on its own and check the droppings over the next 24 hours.
How much?
Rabbit.org and the Merck Veterinary Manual put fresh vegetables at about 1 cup per 2 pounds (about 1 kg) of body weight per day, mostly leafy greens. Lettuce can be one of the at least three leafy greens the House Rabbit Society recommends each day.
Romaine versus iceberg
Romaine is darker, leafier and on every rabbit-safe list used here. Iceberg is pale, crisp and mostly water, which is why the Royal Veterinary College specifically excludes iceberg and light colored leaves.
Rabbit.org takes a measured view: iceberg is safe to eat but low in nutrients, and large amounts can cause diarrhea. A shred that falls into the bowl is not an emergency, but iceberg should not be part of the salad plan.
Building a daily salad around lettuce
Lettuce works best as one ingredient among several. The House Rabbit Society recommends at least three different leafy greens a day, and PDSA suggests five or six different types of fresh plants, grass or vegetables daily.
Some greens need rotating. The House Rabbit Society marks greens high in oxalic acid and suggests that only one of the three daily greens come from that group:
- Not marked for rotation: romaine, red and green leaf lettuce, cilantro, basil, arugula, bok choy, carrot tops
- Marked for rotation because of oxalic acid: parsley, spinach, Swiss chard, mustard greens, beet greens, radish tops, sprouts
Bagged salads and washing
Bagged salad mixes save time but need a closer look. PDSA advises never feeding a rabbit anything you cannot identify, and some mixes contain onion family greens or dressing packets.
Wash lettuce even when the bag says ready to eat. Because of rabbit hemorrhagic disease virus type 2 (RHDV2), the House Rabbit Society recommends washing all vegetables for at least two minutes in a bowl, changing the water several times.
Common questions
Is lettuce good for rabbits?
Yes, as part of a hay-based diet. Dark leaf lettuces are standard rabbit greens. The House Rabbit Society lists romaine and red or green leaf lettuce among its leafy greens, the RSPCA names romaine among good greens to feed daily, and Pasadena Humane lists romaine, green leaf and red leaf lettuce among vegetables that can be fed daily.
Are rabbits allowed to have lettuce?
Yes. Wash the leaves well, then serve them still damp.
Is lettuce bad for rabbits?
Lettuce is not bad for rabbits as long as it is a dark leaf type such as romaine, red leaf or green leaf. Iceberg lettuce is the one to avoid, because it is mostly water, low in nutrients and can cause diarrhea in large amounts.
Can rabbits eat lettuce every day?
Romaine and other dark leaf lettuces can be part of a rabbit's daily greens. The RSPCA lists romaine among greens to feed daily, and Pasadena Humane lists romaine, green leaf and red leaf lettuce among vegetables that can be fed daily.

If your rabbit has eaten something harmful, or stops eating or passing droppings, contact a veterinarian who treats rabbits right away, even if your rabbit seems fine. Rabbits cannot vomit, so do not try to make your rabbit throw up.
