One carrot a day won’t improve your rabbit’s eyesight — it’ll make them sick. Thanks to Bugs Bunny, the entire world believes rabbits live on carrots. The reality is that carrots are sugary treats, not staples. When I first got a rabbit, I loaded up on carrots from the grocery store, only to learn they should be an occasional treat.
The foundation of a rabbit’s diet is Timothy hay — about 80% of what they eat. Carrots should only be given as rare treats due to high sugar. Safe daily veggies include romaine lettuce and herbs, while celery and broccoli need caution.
If you bring a new bunny home and fill their bowl with carrots, you’re setting them up for severe, potentially fatal digestive issues.
Hay makes up most of their diet
A rabbit’s digestive system relies on constant movement. If they stop eating, their gut stops moving (a deadly condition called GI Stasis). To keep things moving and to wear down their continuously growing teeth, 80% of their diet must be unlimited grass hay, such as Timothy or Orchard grass. Hay provides the crude fiber rabbits need, at least 20% fiber content, to keep their gut functioning properly.
Never use alfalfa hay for adult rabbits. Alfalfa is too high in calcium and protein and can cause bladder sludge, urinary tract infections, and obesity. Reserve alfalfa for baby rabbits under 6 months old.
Carrots: the treat Bugs Bunny lied about
Yes, but only as a dessert. Carrots are “root candy.” They’re packed with sugar and carbohydrates—a single medium carrot contains about 5 grams of sugar, which is a massive amount for a small rabbit’s system. Feeding a rabbit a whole carrot every day will lead to obesity, tooth decay, and digestive blockages. A baby carrot once or twice a week is plenty. Better yet, offer the carrot tops (the green leafy part) instead; they’re much lower in sugar and packed with nutrients.
Celery and broccoli: handle with care
-
Can rabbits eat celery? Yes, celery is crunchy and a great water source. However, you must chop it into small 1-inch pieces. The long, stringy fibers in celery stalks can wrap around a rabbit’s teeth or cause internal blockages if swallowed whole. Peeling the strings off before chopping is even safer.
-
Can rabbits eat broccoli? Technically yes, but proceed with caution. Broccoli is a cruciferous vegetable known to cause gas. Rabbits can’t pass gas easily, and severe bloating can be deadly. Feed only tiny florets rarely, once a week at most. If you notice your rabbit’s belly looking distended or hear gurgling sounds, skip broccoli altogether.
Can Rabbits Eat Cucumbers and Tomatoes?
-
Cucumbers: Yes! Cucumbers are very high in water and low in nutrients. They’re a safe, refreshing treat on a hot summer day, but feeding too much can cause runny stools. Two or three small slices per serving is ideal.
-
Tomatoes: Can rabbits eat tomatoes? The red, fleshy fruit of the tomato is safe in small amounts—a cherry tomato cut in half is a perfect serving. WARNING: Never let your rabbit eat the green leaves, vines, or stems of a tomato plant. They’re highly toxic and belong to the deadly nightshade family. Even a small amount of tomato plant material can cause severe digestive distress.
Safe Daily Vegetables
These veggies can be fed daily as part of a balanced diet:
- Romaine lettuce: Dark, leafy greens work well. Red leaf and green leaf lettuce are also good.
- Fresh herbs: Basil, cilantro, mint, parsley, and dill are all safe and loved by rabbits.
- Bell peppers: Any color, chopped into small pieces. High in Vitamin C.
- Zucchini: Soft, low-calorie, and hydrating.
Water and Hydration
Rabbits need constant access to fresh, clean water. A healthy adult rabbit drinks about 50-150 ml per kilogram of body weight per day—that’s 200-600 ml for an average 4 kg rabbit.
- Bowl vs Bottle: Many rabbits prefer drinking from a heavy ceramic bowl because it’s more natural than licking a metal sipper tube. Bowls also encourage higher water intake. However, bowls need daily washing and can be tipped over.
- Winter care: In cold weather, check that the water hasn’t frozen if the rabbit is housed outdoors (though I recommend indoor housing only).
Foods That Are Toxic to Rabbits
Some common garden and kitchen foods can kill a rabbit:
- Iceberg lettuce: Contains lactucarium, which can be toxic in large amounts, and has almost no nutritional value.
- Potatoes and potato peels: High in starch and contain solanine, a toxic compound.
- Rhubarb: Highly toxic, causes kidney failure and death.
- Chocolate and caffeine: Can cause heart failure.
- Meat, dairy, eggs: Rabbits are strict herbivores and can’t digest animal proteins.
- Bread, pasta, crackers, cereal: High in starch and sugar, causes severe GI upset.
My rabbit’s gut has never been happier since I switched to quality Timothy hay — it’s the one expense you should never cut corners on.
