Can Rabbits Have Romaine Lettuce?

Romaine lettuce, as mentioned, is also called as cos lettuce. Even though they may not really be as nutritious as other varieties, such as leaf lettuce, they are ideal for rabbits. Your rabbit will most likely love the taste, and even enjoy the benefits of the nutrients that are included within.

This variety of lettuce needs to be fed with extra caution compared with other varieties. It has more water content. True, it does not diminish the nutrition, but it may result in watery stools. As a helpful tip, you may want to feed your rabbits with romaine lettuce, along with other varieties of crunchy veggies.

Rabbits love eating romaine lettuce because of its unique crunch. Avoid feeding your rabbit with entire lettuce, or it will cause some tummy pains. It may be best to shred the leaves first into smaller bits and pieces.

It would also be best to take into consideration knowing about the origin of the romaine lettuce that you are feeding your rabbit. A few years back, there was an outbreak of e.Coli in certain places, and they were mostly associated with romaine lettuce, which was grown in the central part of California. Of course, the threat has already passed off, but taking some caution would do you no harm.

Aside from romaine lettuce, lamb’s lettuce is also considered safe. Experts agree that the darker the leaves are, the healthier they are. Choose varieties that do not contain too much amount of lactucarium, which is a substance that is highly toxic for your pets, when given in high doses.

Even varieties that are considered as safe need to be given in moderation. There may be other healthier and fresher veggie options that they would really love eating. Balance is the key to moderation, as well.

Rule of Thumb

As a general rule of thumb that you can follow when unsure, experts warn against varieties that are light-colored. Generally, these types are high in water content, with little nutritional value. Choose darker ones, as they are generally more fibrous. This includes romaine lettuce. They can be fed to your bunnies in moderation as they have higher fiber content level, as well as other valuable nutrients.

Moderation means that your rabbits should not be fed with lettuce every day, even with romaine lettuce. The reason? Lettuce is not the main part of their diet. Rabbits are generally herbivores, which means that their diet primarily includes hay, some leafy greens, and little amounts of pellets. There are also some fruits permitted and certain non-leafy vegetables, along with some commercially available options.

Romaine lettuce need not be considered as the cornerstone of the diet of your rabbit. In fact, it is even best to leave it as a treat to your pets.  Twice a week is enough, even more than that. Make sure that when you feed your rabbit with romaine lettuce, it should be thoroughly washed.

Make sure to shred the leaves well, and if possible, having them with other vegetables, such as chopped bell peppers. Avoid serving other vegetables, especially those with high calcium content, together with lettuce. Good options would include broccoli or spinach.

If your rabbit is a newbie to romaine lettuce, you may want to start with smaller quantities. Too much of anything that is new for them can upset their stomach. The recommended daily amount for fresh veggies for your pets is two cups per 6 pounds of their body weight.


Yes, your beloved rabbits can consume romaine lettuce as part of their meal. Lettuce is filled with nutrients and fiber. The best part? Low calories. However, moderation is very important. It is filled with vitamins and minerals that will prove to be beneficial to the health of your rabbit. Moderation is a critical factor. Think about this – your rabbit can get too much of these vitamins, which is actually as harmful as having too few vitamins.
