Rabbits are fascinating herbivores with specific dietary needs. Their digestive systems are designed for a near-constant intake of fiber, crucial for maintaining a healthy gut. While they primarily eat greens, veggies, and fruits, not all varieties are safe for them. Many human treats and even some commercially available rabbit foods can be harmful. This guide outlines what foods bunnies can’t eat to ensure your furry friend’s health and safety. Always consult with a rabbit-savvy veterinarian before introducing new foods to your rabbit’s diet. If your rabbit ingests any of the items listed below, contact your veterinarian immediately.
- Avocados
- Chocolate
- Fruit Seeds/Pits
- Raw Onions, Leeks, Garlic
- Meat, Eggs, Dairy
- Broad Beans and Kidney Beans
- Rhubarb
- Iceberg Lettuce
- Mushrooms
- House Plants
- Processed Foods (Bread, Pasta, Cookies, Crackers, Chips, etc.)
- Raw Potatoes
Avocados: A Toxic Treat
Avocados, while a healthy snack for humans, contain persin, a compound toxic to rabbits. Persin is present in all parts of the avocado – skin, pit, leaves, and flesh. Ingesting toxic levels of persin can cause behavioral abnormalities, breathing difficulties, and potentially lead to congestive heart failure, which can be fatal.

Chocolate: A Dangerous Indulgence
Chocolate is highly toxic to rabbits due to the presence of theobromine and caffeine. The darker the chocolate, the higher the risk. Signs of chocolate toxicity include diarrhea, restlessness, hyperactivity, trembling, panting, elevated heart rate (tachycardia), and elevated temperature (hyperthermia). Prompt treatment is crucial, as chocolate toxicity can be fatal.
Fruit Seeds/Pits: Hidden Cyanide Dangers
Always remove seeds and pits before feeding fruit to your bunny. While small amounts of fruit flesh are generally safe, the seeds and pits of many fruits contain trace amounts of cyanide. Apples, pears, apricots, peaches, plums, mangos, and cherries are common culprits. While the cyanide content is usually low, it’s best to avoid these seeds and pits altogether.

Raw Onions, Leeks, Garlic: Oxidative Damage
Raw allium vegetables like onions, leeks, and garlic contain n-propyl disulfide, an oxidant that can cause oxidative damage to red blood cells in rabbits. This can lead to hemolytic anemia, a potentially fatal condition. Symptoms include pale gums, ataxia (stumbling), weakness, loss of appetite, and lethargy.
Meat, Eggs, Dairy: Unsuitable for Herbivores
As herbivores, rabbits should never consume meat, eggs, or dairy products. Their digestive systems are specifically designed to break down low-fat, high-fiber vegetation, unlike carnivores or omnivores, which can digest animal protein. While some rabbits might find dairy products enticing, they can cause gastrointestinal upset and increase the risk of obesity or dysbiosis (microbiome disruption).

Broad Beans and Kidney Beans: Digestive Disruptors
Broad beans (fava beans) and kidney beans are high in carbohydrates, which can disrupt a rabbit’s delicate gastrointestinal system, leading to soft stools, diarrhea, abdominal discomfort, bloating, and dysbiosis. They also contain high levels of phosphorus and calcium and are acidic, making them unsuitable for rabbits.
Rhubarb: Oxalic Acid Concerns
Rhubarb contains a high concentration of oxalic acid in all parts of the plant. While small quantities of oxalic acid are not toxic, excessive consumption can interfere with calcium absorption and lead to toxic effects. Symptoms include a swollen, painful mouth, decreased appetite, bloating, abdominal discomfort, diarrhea, and lethargy.

Iceberg Lettuce: Low Nutritional Value and Potential Harm
While dark, leafy lettuces like romaine and green leaf are good for rabbits, iceberg lettuce contains lactucarium, which can be harmful in large quantities. Furthermore, iceberg lettuce offers minimal nutritional value.
Mushrooms: Mycotoxin Risks
Even store-bought mushrooms should not be fed to rabbits. They can contain mycotoxins that remain present whether raw or cooked, potentially causing diarrhea, gastrointestinal discomfort, organ damage, and neurological deficits.

Houseplants: Unknown Chemical Exposure
Treat all houseplants as potentially toxic to your rabbit, even if they are considered safe. It’s often difficult to know if a plant has been exposed to chemicals before you bring it home. Keep houseplants well-trimmed and out of reach.
Processed Foods: Unhealthy and Unsuitable
Avoid sharing processed foods like bread, pasta, cookies, crackers, and chips with your bunny. These foods are high in carbohydrates and sugar, leading to digestive upset, abnormal stools, abdominal discomfort, dysbiosis, obesity, and related health problems. Offer small amounts of appropriate fruits or commercially available rabbit treats instead.

Raw Potatoes: Solanine Toxicity
Raw potatoes contain solanine, a toxic alkaloid that can cause decreased appetite, digestive upset, abdominal pain, and lethargy in rabbits. Even if toxic quantities are not ingested, potatoes are calorically dense and high in starch, which can disrupt the gastrointestinal system.
It’s crucial to avoid feeding your rabbit the foods listed above to ensure their health and well-being. Plenty of rabbit-approved greens, fruits, and veggies can provide a nutritionally appropriate and interesting diet. If you suspect your rabbit has ingested a food from this list or exhibits any of the symptoms described, contact your veterinarian immediately.
