Rabbits are sensitive to a surprisingly long list of common foods, plants, and household materials. Some, like avocado and chocolate, can be fatal even in small amounts. Others, like raw potatoes and iceberg lettuce, cause harm only over time or in larger quantities. Knowing what to keep away from your rabbit is one of the most important parts of keeping them safe.
Foods That Are Toxic to Rabbits
Several everyday kitchen items are dangerous for rabbits. The most serious offenders include:
- Avocado: Every part of the avocado plant, including the flesh, skin, pit, and leaves, contains a compound called persin. In rabbits, persin damages the heart muscle directly. A documented case found that 14 rabbits died of congestive heart failure within 30 hours of eating fresh avocado leaves. Their hearts showed degeneration and death of muscle cells, along with fluid buildup around the heart and lungs. This is not a food to take chances with.
- Chocolate: Contains both theobromine and caffeine, which rabbits process far more slowly than humans. Darker chocolate carries a higher risk because theobromine concentrations increase with cocoa content.
- Onions, leeks, and garlic: These allium vegetables contain a compound that attaches to red blood cells. A rabbit’s body treats the altered cells as foreign and destroys them, leading to hemolytic anemia, a potentially fatal drop in red blood cells.
- Rhubarb: High in oxalic acid, which binds to calcium in the body and forms crystals that can deposit in the kidneys. This also drains calcium from the blood, creating a dangerous imbalance.
- Raw potatoes: Contain solanine, an alkaloid that causes loss of appetite, digestive upset, abdominal pain, and lethargy.
- Fruit seeds and pits: Apple seeds, pear seeds, and the pits of apricots, peaches, plums, mangos, and cherries all contain trace amounts of cyanide.
Two foods people sometimes assume are safe deserve special caution. Iceberg lettuce contains lactucarium, a chemical that can harm rabbits in large quantities. It also has almost no nutritional value, so there’s no reason to offer it. Mushrooms can contain various toxins that remain present whether raw or cooked.
Rabbits are strict herbivores. Meat, eggs, and dairy products should never be offered. Their digestive systems simply aren’t built to process animal proteins or fats, and these foods can cause serious gastrointestinal problems.
Dangerous Plants Indoors and Outdoors
The safest approach to houseplants is to treat every single one as toxic. The Rabbit Welfare Association recommends this blanket rule because the sheer variety of houseplants makes it impossible to maintain a reliable safe list. Keep all houseplants on high shelves or in rooms your rabbit never enters. If leaves are about to drop within your rabbit’s reach, clip them off and throw them away before they fall.
Outdoor gardens carry similar risks. Common garden plants known to be toxic to rabbits include foxglove, lily of the valley, nightshade, hemlock, ragwort, and buttercups. If your rabbit has access to a yard or garden run, inspect the area thoroughly and remove or fence off anything you can’t positively identify as safe. Wild plants that grow near fences and edges are easy to overlook but often the first thing a curious rabbit nibbles.
Unsafe Wood and Bedding
Rabbits chew constantly to wear down their teeth, so the type of wood they have access to matters. Pine and cedar shavings should be avoided as litter or bedding. These softwoods release volatile chemicals called phenols, which give them their distinctive smell but can irritate a rabbit’s respiratory system and liver over time. Ponderosa pine needles are especially dangerous and should never be used.
Safe alternatives for chewing include apple, willow, and aspen wood, as long as the branches haven’t been treated with pesticides. Kiln-dried pine, which has had most of its phenols removed through heat treatment, is generally considered acceptable for litter, but untreated softwood shavings are not.
Household Chemicals and Cleaning Products
Rabbits spend a lot of time on the floor, which means they’re in direct contact with whatever you clean it with. Most disinfectants are toxic while still wet but safe once fully dry. The practical rule is to keep your rabbit out of any room you’re actively cleaning and wait until all surfaces have dried completely before letting them back in. Never mix bleach with ammonia or other cleaners, as this produces toxic fumes that are dangerous to both you and your rabbit.
Store all cleaning products, detergents, and chemical containers where your rabbit can’t reach them. Rabbits chew through packaging easily, and even small exposures to concentrated cleaners can cause burns to the mouth, throat, and digestive tract.
Signs Your Rabbit May Have Been Poisoned
Rabbits hide illness instinctively, so changes can be subtle at first. The most common early warning signs involve their gut. A rabbit who has eaten something toxic will typically eat less over a period of two to seven days, produce fewer and smaller droppings that look dark and dry, and drink less water. Left untreated, they stop eating entirely and fecal production ceases.
Pain in rabbits looks different than in cats or dogs. A rabbit in pain becomes reluctant to move, sits hunched up, grinds their teeth, and may dig or scratch at the floor. They often become less social and withdraw to a corner. In more acute cases, such as after eating something that causes a sudden obstruction or severe toxicity, the rabbit refuses all food abruptly and becomes visibly depressed and weak.
Some toxins cause watery, brown diarrhea that may contain blood or mucus and soils the fur around the hindquarters. Neurological signs like loss of coordination, head tilting, or seizures are less common but indicate a serious emergency. Difficulty breathing can signal cardiac involvement, particularly with toxins like persin from avocado.
What to Do If Your Rabbit Eats Something Toxic
Do not try to make your rabbit vomit. Rabbits physically cannot vomit, so any home remedy aimed at inducing vomiting is pointless and potentially harmful. Your only real option is to get veterinary help fast.
Call your veterinarian or an emergency animal clinic immediately. If you know or suspect what your rabbit ate, note the substance, the approximate amount, and when it happened. This information helps the vet determine how urgently your rabbit needs treatment and what kind of intervention is appropriate. If you cannot reach a vet, the ASPCA Poison Control Hotline (888-426-4435) and the Pet Poison Helpline (855-764-7661) both operate around the clock and can guide you through first aid steps while you arrange transport to a clinic.
Speed matters with most rabbit toxins. Avocado can kill within hours. Hemolytic anemia from onions progresses quickly once red blood cells start breaking down. Even with less immediately lethal substances, a rabbit’s small body size means toxic concentrations build up faster than they would in a larger animal.
