Is Iceberg Lettuce Toxic To Rabbits?


Let’s get this out of the way… iceberg lettuce is not toxic to your rabbit but it is just not recommended for your rabbit because of its high water content and less to no nutritional benefits. 

Like many lettuces, iceberg lettuce contains lactucarium, a milky fluid that is not good for your rabbit. Lactucarium can get to the leaves while the rabbits eat the lettuce and it is bad for them. 

Lactaturium is a chemical agent that causes both sleepiness and some pain relief (analgesia). It is also called rabbit opium because if your rabbit consumes lactucarium it gives the same symptoms as the actual opium. 

The consumption of iceberg lettuce causes agitation, nausea, dizziness, hallucinations, and blurred vision in your rabbit due to the presence of lactucarium. If you witness any of these symptoms then it is better to rush your bunny to the vet to be on the safe side. 

Wild iceberg lettuces are however different from cultivated iceberg lettuces. In both the lactucarium contents are different. It is greater in the wild lettuces which is why that’s more dangerous for the rabbits. 

Because of this, you have to be very careful if you are going to let your rabbit roam around wild areas or even in your garden. 

What Happens If My Rabbit Eat Iceberg Lettuce?


You don’t have to worry even if your rabbit eats iceberg lettuce. It will not necessarily kill your rabbit. But it still will cause a few health problems in your rabbit. 

Eating iceberg lettuce can cause dizziness, hallucination, nausea, and diarrhea in your rabbit. Most of the symptoms are harmless and will wear off in a couple of hours if given care. 

But if your rabbit eats too much lettuce, then it won’t be the lactucarium that will affect your rabbit, it is the water content of the lettuce. Iceberg lettuce contains the most amount of water content. 

Even though water will keep your rabbit hydrated, too much water with too few nutrients and fiber is not your rabbit’s best friend. Consuming too much lettuce will cause diarrhea in your rabbit and cause dehydration and fatigue. 

Diarrhea in rabbits could become a health risk as it will make your rabbit lose all the water content in its body which can cause dehydration. Rabbits and dehydration don’t go hand in hand. That’s why it’s important to make sure that your rabbit doesn’t consume too much lettuce.
