Can Rabbits Eat Lettuce?

Can Rabbits Eat Lettuce?

What can you feed your rabbit? When you have a pet rabbit, this question will make up most of your days. It sounds like a bit much, but we’re not kidding!

The list of foods that your bunny shouldn’t eat is not a short one. If your little buddy gets his hands on some chocolate, for instance, it could suffer severe health problems, and the famous sweet could even lead to death!

Same with avocados, onions (pretty much all onions), and fruit seeds. These are just some examples, but we do have a point, don’t worry. These foods are really unlikely to be found in your rabbit’s tiny hands. It’s not going to go to the store and accidentally get some avocado oil for its cooking. 

But if you’ve been researching these sorts of lists, you may have come across an interesting food – Iceberg Lettuce. But how can this be? Lettuce is one of the first foods that come to mind when you imagine a bunny nibbling on something. Carrots hold the first spot, sure, but lettuce is definitely up there. 

After finding this out, you may be wondering – Can rabbits eat lettuce? It does seem as if the Iceberg is entirely off the table, but it’s a bit more complicated than that. Don’t worry, though; we’ll explain everything. So let’s put on our detective hats and figure this out. Heads up, we’ll cover a few more nutritional subjects along the way. You can never get too informed, right?

Can Rabbits Eat Lettuce?

So can rabbits eat the green stuff – YES, they absolutely can. But as with all foods that our sensitive little friends consume, there are a few things you need to know. Rabbits have a sensitive digestive tract.

The only thing that they should be eating on a regular basis is hay. But hey, they deserve a little treat now and again!

Basically, the first rule for any sort of treat you give to your rabbit is this – try it and see. Not all rabbits are equals, and some might munch up a bunch of lettuce without any negative side effects, while others have serious problems digesting it. So whatever food you might want to give to your rabbit, start with small portions and monitor the situation.

Small portions don’t mean that you should have a little piece of lettuce and stare at your rabbit all day long. But you do need to know how your bunny’s body is reacting to the new food. The best way to monitor for possible negative changes is to always keep an eye on your pet’s stool samples.

This rule can pretty much be applied to any pet, rabbits, cats, dogs, parrots, etc. The stool can tell you everything you need to know about your pet’s health! 

There are always other symptoms that certain toxic foods produce, but the most common problem that rabbits have with foods is the inability to process them. If food can’t be processed, the rabbit will develop diarrhea, which can be fatal for our sensitive little rabbits. 

So alright, you know that you need to keep an eye out and play it safe with new foods. But let’s get back to the lettuce. Which one should you get? Why are some toxic but others not? There are so many questions!

Don’t worry; we’ll answer all of them. Firstly we must mention that all lettuce is toxic if your rabbit consumes too much of it. This may sound dangerous, but don’t worry. Everything is toxic if you consume too much. The same rules apply to humans. Rabbits just have incredibly small digestive tracts. This means that they go overboard without trying too hard. 

With that said, let’s take a look at the lettuce list!

Good Lettuce Vs. Bad Lettuce

So there are two kinds of lettuce as far as your rabbit’s diet is concerned – Iceberg and non-Iceberg. It seems simple enough. Well, as we mentioned, all lettuce needs to be fed to rabbits in moderation. 

There are certain substances that are found in all kinds of lettuce that could be toxic to your bunny. Iceberg Lettuce just has too much of them! But more on that in a minute:

Romaine Lettuce

Romaine lettuce, also known as Cos lettuce, is completely safe to feed to your rabbit. While it does contain relatively high water levels, it’s nothing compared to something like an Iceberg. 

Why is water a problem? Well, rabbits don’t need too much water, and by eating too much of any lettuce, they kind of drink too much. This results in a runny stool, which could have a negative effect on digestion. On the other hand, Romaine lettuce contains calcium, magnesium, potassium, phosphorus, and a good number of healthy vitamins. Add this all up, and you have a tasty, crunchy treat!

Green/Red Leaf Lettuce

Green leaf lettuce is pretty much the perfect lettuce for your bunny. It has a well-balanced nutritional chart, which means that it doesn’t go overboard with any of its healthy substances.

Red leaf Lettuce is pretty much the same as its green counterpart, but just better looking. Not that we’re trying to say anything bad about the green leaf, but red leaf lettuce adds a bit of color to your rabbit’s treats. And it’s not only color; red leaf lettuce packs more vitamins than its brother does – especially vitamins A and K. 

But no matter how well balanced it is, we still advise you to give it to your rabbit in moderation!

Butter Lettuce

Butter lettuce may not be as famous as its brothers, but it’s still a great vegetable, especially for your rabbit! The name Butter Lettuce is actually a group rather than just a single vegetable. The difference between Butter Lettuce and its brothers is the tender, soft leaves that are always colored with a rich green color. Boston and Bibb Lettuce are the most famous of the group. 

Like all the others so far, it’s a well-balanced treat that should be given in moderation. 


This may not be the most well-known lettuce, but we just had to put it on the list! Arugula is a staple of many Mediterranean salads. This makes sense since it comes from the, you guessed it, the Mediterranean! It’s not your usual lettuce, once it has a kind of spicy taste to it. But don’t worry, it’s still a healthy veggie for your bunny. It has calcium, potassium, vitamin C, etc. 

Basically, it’s a healthy treat – no surprise here!

Iceberg Lettuce 

Last but not least, the infamous Iceberg! The only real threat for your bunny on this list, the Iceberg, is just a bit too much for our pet’s digestive tract. There are two main problems with Iceberg lettuce. First of all, it contains too much water. 

We know that all lettuce contains water, but as we mentioned earlier, too much of any substance is not good. Your bunny doesn’t need a lot of water and eating Iceberg lettuce, it basically gets water drunk. This causes diarrhea and other problems.

The second problem is a substance called lactucariumwhich basically means milk in Latin. THat’s the white liquid that comes out of the Iceberg when you cut it. Lactucarium is opium for your rabbit. It has a sedative effect on rabbits, and while it can’t harm them in very small amounts – it’s easy to go overboard. A high amount can be deadly. 

Health And Nutrition

So what are the health benefits of lettuce? 

Well, while it’s easy to go overboard, lettuce still has some great benefits if given to your rabbit in moderate amounts. It will keep your pet well hydrated. The high amount of fiber and low amount of carbs and proteins means that it is great for your friend’s digestive tract.

And that’s not all. The array of vitamins in all these types of Lettuces makes sure your bunnies’ skin, eyesight, and blood stay healthy and sharp! The famous veggie also lowers the chances of certain cancers and heart diseases. 

Let’s take a look at the nutritional values of these bunny salads, just to get a feel for what we’re dealing with:
