What Rabbits Shouldn’t Eat: A Guide for Concerned Rabbit Owners
Rabbits are adorable and popular pets found in many households all around the world. Their fluffy fur and curious nature make them perfect companions. However, as harmless and innocent as they may appear, when it comes to their diet, there are certain precautions that rabbit owners should absolutely consider. Not everything that looks green and tasty is healthy for them. In this article, we delve into some foods that can be harmful or even toxic to rabbits.
Iceberg Lettuce
Many people assume that all types of lettuce are safe for rabbits, but this is a misconception. Specifically, iceberg lettuce contains lactucarium, a substance that can cause diarrhea in rabbits. Instead of iceberg lettuce, rabbit owners should opt for other green leafy vegetables like dandelion or arugula.

Beans and Peas
Though they are nutrient-rich, both green beans and peas can cause bloating in rabbits, which can be very uncomfortable for the animal. It’s best to exclude them from your rabbit’s diet.
Nightshade Vegetables
This category includes some of our favorite vegetables like potatoes, tomatoes, and eggplants. For rabbits, especially the green parts of these plants can be toxic. It’s advisable to completely avoid them.

Onions and Garlic
They contain sulfur compounds that can damage rabbit’s blood and lead to anemia. This condition can have severe health implications and should be taken seriously.
Grains and Bread
Some rabbit owners believe that bread and grains are fine because they appear in many rabbit feeds. However, when overfed, they can lead to digestive issues and should thus be given in moderation.
Chocolate and Sweets
These are an absolute no-go for rabbits. They contain theobromine, which is toxic to rabbits and can be fatal in large amounts.

Avocado
Some animal lovers might think this nutritious fruit is good for their bunnies, but that’s not the case. All parts of the avocado, including the skin and pit, contain persin, a substance toxic to rabbits.
Rhubarb
The leaves of rhubarb can cause kidney issues in rabbits. While the stalk is edible for humans, rabbits should avoid both stalks and leaves.

Frequently asked questions
Which foods are toxic to rabbits?
Dangerous foods include avocado in all its parts, chocolate and candy, onions and garlic, rhubarb and nightshade plants such as potatoes, tomatoes and eggplants, especially their green parts. This list isn’t complete. If you’re unsure about a food, it’s better to leave it out or ask your vet.
What should I do if my rabbit has eaten something toxic?
Remove any leftovers right away and note down what your rabbit ate and roughly how much. Then call a vet or an emergency vet service immediately, rather than waiting to see if symptoms appear. Don’t try home remedies on your own; follow your vet’s instructions instead.
Can my rabbit eat lettuce?
Not every type of lettuce is equally suitable. Iceberg lettuce contains lactucarium, which can cause diarrhea in rabbits, so it shouldn’t end up in the bowl. Other leafy greens such as dandelion or arugula are a better choice. Introduce new greens slowly so your rabbit’s sensitive digestive system can adjust.
Are bread and grains good for rabbits?
Bread and grains aren’t part of a rabbit’s staple diet and can cause digestive upsets if given in large amounts. If at all, they should only be offered rarely and in small quantities. The foundation should be hay, fresh vegetables and suitable rabbit food, which keeps your rabbit healthy.
