Can Rabbits Eat Iceberg Lettuce: Surprising Foods That Aren’t Safe for Bunnies

No, iceberg lettuce is not safe for rabbits and should not be eaten by them. Iceberg lettuce contains lactucarium, which can be toxic in massive amounts, high in water content, and low in nutritional value. Thus this seemingly harmless vegetable can cause diarrhea, vomiting, and excessive thirst in rabbits. 

If you suspect your rabbit has eaten iceberg lettuce, monitor its symptoms closely and do not panic. Contact a veterinarian immediately if you notice any problems, such as diarrhea or excessive thirst.

Iceberg Lettuce Is Bad for Rabbits

Iceberg lettuce is a popular lettuce choice for feeding rabbits, especially in the summer. However, there may be better choices than iceberg lettuce. Other vegetables and fruits are a better option for feeding your bunny. 

Hay or fresh vegetables are enough to satisfy your pet’s hunger. As long as he’s not eating anything else that isn’t plant-based (including other types of lettuce), there’s nothing wrong with him!

If you choose to feed your rabbit iceberg lettuce, make sure it’s only a tiny part of their diet daily, as it is not a good source of nutrients. Additionally, if eaten, large quantities of iceberg lettuce can cause GI problems, so feed them to your bunnies sparingly.

Lactucarium Content

Some people believe lactucarium has health benefits, such as oral detoxification and improving moods and energy levels; however, lactucarium can be harmful if consumed in large quantities by rabbits.

What Can Happen if a Rabbit Eats Iceberg Lettuce

Several possible health problems can arise from feeding iceberg lettuce to your rabbits, such as diarrhea, weight loss, and even death. If you do happen to feed them some iceberg lettuce, monitor their symptoms closely and consult with a vet if there is any sign of illness.

Should I Worry if My Rabbit Eats Some Iceberg Lettuce?

Feeding your rabbit a small amount of iceberg lettuce is not harmful. When fed in moderation, iceberg lettuce is a healthy option for your rabbit. If you are concerned about your rabbit overeating iceberg lettuce, try cutting it out of their diet entirely for a day or two and see if there is an improvement in their behavior.

Iceberg lettuce can be a harmful food for rabbits, but if you notice your rabbit has eaten it, there is no need to panic. Instead, give your pet plenty of water and electrolytes to help them with digestion. If it becomes an issue or if you notice any change in behavior in your pet, you can take them to the vet for examination or switch to a different type of food altogether.

Surprising Foods You Shouldn’t Feed Your Rabbit

It is essential always to consult a vet if you have any doubts about what your bunny should or shouldn’t eat. Checking the ingredients label on food can help you avoid feeding your rabbit foods that could potentially kill them. 

There are a lot of foods (especially plant-based ones) that may seem harmless at first but could cause various issues when eaten by rabbits. Iceberg lettuce, for example, is unsuitable for bunnies and should be avoided! 

Other dangerous foods include chocolate, potatoes, grapes, raisins, and avocados – all of which are high in sugar or carbs content, might not be suitable for bunnies’ health, and can even cause weight and other health problems if eaten regularly.

Avoid giving them the said foods to avoid complications. For example, if you notice your rabbit becoming unwell or having problems after eating the mentioned foods, it is best to take him to the vet as soon as possible. 

Onions and Garlic

Your rabbit can tolerate onions and garlic but should consume only a few amounts at a time. Onion and garlic are toxic if ingested in large quantities, so keep them out of reach of pets!


If his diet includes avocados only occasionally (as a treat), there is no reason for concern. Avocados are healthy food for rabbits and can be used in their diet to provide them with the essential vitamins, minerals, and fatty acids they need. 

However, as this has a high sugar content, it is not advisable to feed it to your bunny in high amounts. Always keep an eye on your rabbit; contact your vet immediately if you have any concerns.


Try to feed your rabbit other vegetables, as potatoes are high in carbs and sugar. Only feed them sparingly as it can cause obesity problems down the line if eaten regularly.


Chocolate is one of the most popular food on earth. However, it is unsuitable for your rabbits as it contains high sugar levels that could cause them to gain weight, especially if eaten regularly.


Rhubarb is another hardy vegetable that can be toxic for your rabbits if consumed in large quantities due to its oxalic acid content. Make sure to keep these out of your pet’s reach.

Alternative Vegetables That Are Safe for Your Rabbits 

Chard, spinach, broccoli, cauliflower, brussels sprout, and kale are all high in fiber which helps with regularity and digestion. These vegetables are an excellent choice for rabbits instead of iceberg lettuce. 

They’re also a good source of vitamins A and C and minerals like calcium. However, as with all food for your bunnies, it is important to feed these to your pets in moderation, as giving them too much can cause obesity problems in the long run.
