Foods Rabbits Cannot Eat

Introduction

Rabbits have a sensitive digestive system, and many common foods that are safe for humans or other pets can be dangerous — even fatal — for rabbits. Knowing what foods rabbits cannot eat is just as important as knowing what they should eat. Here's a comprehensive list of foods to keep away from your bunny.

Toxic Foods That Can Be Fatal

These foods should never be given to rabbits under any circumstances:

• Avocado — Contains persin, a fungicidal toxin that can cause respiratory distress and heart failure in rabbits.
• Onions, garlic, leeks, and chives — Contain compounds that damage red blood cells and can cause life-threatening anemia.
• Rhubarb — Contains oxalic acid in toxic concentrations; can cause kidney failure.
• Chocolate — Contains theobromine, which is toxic to rabbits and many other animals.
• Caffeine (coffee, tea, energy drinks) — Highly toxic to rabbits.
• Alcohol — Even tiny amounts can be fatal.
• Xylitol (found in sugar-free gum, candy, and some peanut butters) — Extremely toxic.

Foods That Cause Digestive Problems

• Iceberg lettuce — Contains lactucarium, which can cause diarrhea. Very low in nutrition.
• Corn — The hard outer shell of corn kernels cannot be digested and can cause dangerous blockages.
• Beans and legumes — Cause excessive gas, which can be life-threatening for rabbits (GI stasis).
• Potatoes and sweet potatoes — Too high in starch; can disrupt gut bacteria balance.
• Bread, crackers, and pasta — High in simple carbohydrates that ferment in the gut.
• Nuts and seeds — Too high in fat; can cause obesity and digestive issues.
• Dairy products — Rabbits are lactose intolerant.
• Meat — Rabbits are herbivores; meat can cause serious illness.

High-Sugar Foods to Severely Limit

• Fruit — Safe in very small amounts (1–2 tbsp), but too much causes obesity and dental disease.
• Carrots — Contrary to popular belief, carrots are high in sugar and should only be given as an occasional treat.
• Commercial rabbit treats with added sugar, honey, or yogurt drops — Avoid these entirely.

Plants and Houseplants That Are Toxic

• Lilies
• Foxglove
• Nightshade
• Ivy
• Philodendron
• Pothos
• Aloe vera
• Tulips and daffodils

Keep all houseplants out of reach of free-roaming rabbits.

What to Feed Instead

Stick to the safe rabbit diet: unlimited Oxbow Orchard Grass Hay, measured high-quality pellets, fresh leafy greens, and clean water. For treats, offer natural timothy grass chew sticks instead of sugary commercial treats.

What to Do If Your Rabbit Eats Something Toxic

If you suspect your rabbit has eaten something toxic, contact a rabbit-savvy vet immediately. Signs of poisoning include lethargy, loss of appetite, difficulty breathing, seizures, or sudden behavioral changes. Keep a pet thermometer on hand and monitor your rabbit's temperature if you suspect illness.

Conclusion

When in doubt, leave it out. Rabbits thrive on a simple, consistent diet of hay, pellets, and fresh greens. Avoid the temptation to share human food with your bunny — what's harmless to you can be deadly to them.
