Foods rabbits cannot eat: the complete toxic food list

Why a rabbit’s diet is so sensitive

The rabbit’s digestive system is both powerful and fragile. An imbalanced cecal flora can trigger gastrointestinal stasis, bloat or enterotoxemia within hours. Some foods act directly as poisons; others simply disrupt fermentation. Knowing both categories is essential.

To understand what a rabbit should eat, read our complete guide to rabbit feeding first.

Outright toxic foods: never give these

Alliums

• Onion, garlic, shallot, chives, leek
• Cause hemolytic anemia (destruction of red blood cells), potentially fatal even in small amounts.

Rhubarb

• Very high in oxalates. Toxic even at low doses.

Avocado

• Persin, present in the flesh, leaves and pit, is cardiotoxic for rabbits.

Potatoes and green tomatoes

• Solanine in the green parts of potatoes and in unripe tomatoes is toxic. Ripe tomato (pulp only) is acceptable in very small amounts.

Common ornamental plants

If your rabbit roams freely in an apartment, remove these plants from its area or place them out of reach.

Strongly inadvisable foods

These are not always immediately lethal but can cause serious digestive problems, nutritional deficiencies or obesity:

• Grains and grain products: bread, biscuits, pasta, rice, oat flakes, muesli, seed mixes. They ferment in the cecum and disrupt the gut flora.
• Legumes: beans, chickpeas, lentils, soy (too high in protein, prone to fermentation).
• Fruit in large amounts: sugars promote diarrhea and obesity. An occasional small bite is acceptable, nothing more.
• Dairy products: rabbits are strict herbivores; their digestive tract cannot tolerate dairy.
• Nuts and oily seeds: too fatty, poorly tolerated.
• Chocolate: theobromine is toxic to rabbits, just as it is to dogs and cats.
• Corn kernels: very sugary, poorly digestible, cause fermentation.
• Cabbage in large quantities: cabbage is not toxic but is highly fermentable; give in small amounts and never raw in large portions all at once.

Commonly misunderstood foods

Carrots

Carrots are not toxic but are very high in sugar. An occasional small slice is fine; making them a daily food increases the risk of obesity. Carrot tops, however, are excellent: fresh, fiber-rich, and very much enjoyed.

Alfalfa for adults

Alfalfa is not forbidden but is unsuitable for healthy adult rabbits: its high calcium and protein content promotes urinary stones and long-term obesity. It is recommended for kits (up to 6 months) and pregnant or nursing does.

Celery and rocket

Well tolerated and recommended in regular rotation. Not to be confused with risky foods.

What to do if your rabbit eats something toxic

1. Do not wait for symptoms: some toxins act with a delay.
2. Precisely identify what was ingested and estimate the amount.
3. Contact an exotic-pet veterinarian or animal poison control center immediately.
4. Do not try to induce vomiting: rabbits are physiologically unable to vomit; any attempt is counterproductive.

If you notice lethargy, seizures, heavy diarrhea, labored breathing or a distended abdomen, this is an emergency: seek veterinary care without delay.
