An Overview on Feeding Tomatoes to Rabbits

When it comes to feeding tomatoes to rabbits, there are a few key things to consider:

  • Nutritional value: Tomatoes contain vitamin C, vitamin A, and antioxidants like lycopene. But they are still relatively low in nutrients compared to leafy greens. They also contain solanine and other compounds that may be harmful in excess.
  • Acidity: Tomatoes have a higher acidity level which can upset some rabbits’ sensitive digestive systems. Their high water content can also cause diarrhea.
  • Safety: Both tomato plant leaves and stems contain poisonous compounds. The fruits themselves are generally safe though if introduced slowly and fed in moderation. Overfeeding may still cause adverse reactions.

So in short – tomatoes make an occasional treat for rabbits but should not become dietary staples. Read on for more details.

Nutritional Profile of Tomatoes for Rabbits

Here is a nutritional breakdown of raw tomatoes:

Nutrient Amount % Daily Value for Rabbits
Vitamin C 13.7 mg 34%
Vitamin A 42 μg 8%
Lycopene 2.63 mg N/A
Water 94% water content N/A
Calories 18 kcal per 100g Low
Protein 0.88g per 100g Low
Fat 0.2g per 100g Low
Carbs / Sugars 3.89g per 100g / 2.63g per 100g Low
Fiber 1.2g per 100g Low

As you can see, tomatoes contain beneficial vitamins A, C and lycopene. But they lag behind leafy greens in key macros like protein and fiber. Their high water and sugar content also make them lacking in nutrients by volume.

So by themselves, tomatoes cannot meet all nutritional requirements for healthy rabbits. Their pros and cons must be weighed as part of a balanced diet:

Potential Benefits

  • High moisture content keeps rabbits hydrated
  • Vitamin C prevents disease and keeps immune system strong
  • Lycopene acts as antioxidant for cell protection
  • Small amounts may aid digestive tract

Potential Drawbacks

  • High water content means low fiber and nutrients by volume
  • Acidity may upset sensitive rabbit stomachs
  • Sugars and carbs promote weight gain if overfed
  • Too much lycopene from tomatoes can be toxic over time

Now let’s look more at the specific compounds that may cause adverse reactions.

Potentially Harmful Compounds in Tomatoes

While tomatoes have some nutritional merit, they also contain the following compounds that can be problematic if rabbits eat too many tomatoes:


Tomatoes contain low levels of solanine, a toxin found in nightshade vegetables. Solanine protects tomato plants from pests and diseases. But excessive intake can be dangerous. Symptoms include:

  • Gastrointestinal upset
  • Abdominal pain
  • Nausea
  • Vomiting
  • Diarrhea

Luckily tomato solanine concentrates heavily in the leaves and stems. It occurs in very low doses within the tomato fruits themselves. But sensitive rabbits may still react poorly if they eat too many tomatoes.


Tomatoes also contain measurable amounts of oxalates. Oxalates bind to calcium in the body, blocking full nutrient absorption. Side effects may include:

  • Kidney stones
  • Calcium deficiency
  • Poor bone health

However, spinach, beet greens, and other leafy rabbit favorites also contain oxalates. So tomato oxalates generally pose low risk if properly balanced in the diet.


In addition, tomatoes are relatively acidic with a pH around 4.2-4.9. Their high acidity comes from citric acid and malic acid within the tomato flesh and juice.

Too much acidity can cause gastrointestinal issues in rabbits by irritating the stomach lining or altering gut flora balance. Diarrhea is a common symptom.

So while vitamins make tomatoes seem attractive for rabbits at first glance, overfeeding carries risks from solanine, oxalates, sugars and acids. Moderation is key.

Are Tomato Plant Leaves and Stems Safe for Rabbits?

No – rabbits should avoid tomato plant leaves and stems entirely.

The green parts of tomato plants contain high levels of solanine as a natural defense mechanism. Ingesting leaves or stems can cause tomato plant poisoning in rabbits.

Symptoms may include:

  • Loss of appetite
  • Gastrointestinal distress
  • Impaired movement
  • Dilated pupils
  • Respiratory paralysis
  • Potentially death

If you grow tomatoes, make sure rabbits cannot access the garden. Never offer them tomato plant parts tops or vines. The fruits themselves are the sole safe tomato-derived food.

Introducing Tomatoes Safely to Rabbits

When first feeding tomatoes to rabbits, take it slow to watch for any intolerances. Here are some tips:

Start with a Small Serving Size

Begin by offering just a tablespoon of ripe tomato flesh once or twice a week. Avoid seeds, juices and skins at first since these concentrated compounds can cause stomach upset.

Pay attention to stool and urine changes as well as behavior for the next 24 hours. Increase gradually while monitoring reactions before making tomatoes a regular treat.

Select Low-Acid Varieties

The level of acids varies greatly between tomato cultivars. Opt for milder, low-acid tomatoes like:

  • San Marzano
  • Cherry tomatoes
  • Roma tomatoes

Avoid heirloom varieties to minimize acid irritation, especially for young or sensitive rabbits.

Mix with Other Ingredients

Serve diced bits of tomato mixed into a rabbits’ usual greens. Add just a few pieces once or twice a week to minimize risks and balance the higher sugar content.

Avoid Giving Tomato Plants or Rotten Tomatoes

Only feed ripe, fresh tomato fruits. Never offer leaves, stems, vines or rotten tomatoes from gardens or kitchens. These contain concentrated plant toxins very dangerous to rabbits. Monitor any outdoor play to prevent unwanted foraging.

Stop Feeding Immediately If Reactions Occur

Even low-acid tomato varieties can cause diarrhea, stomach upset or other issues in some rabbits. Often reactions occur 12-24 hours after eating. Discontinue tomatoes at first sign of any irritation and only reintroduce after symptoms resolve if desired.

How Often Can Rabbits Eat Tomatoes?

If rabbits show good tolerance, tomatoes make a fine occasional treat 2-3 times per week. But they do not deserve a daily place in a well-balanced rabbit diet. Here’s why:

High Water Content

With around 94% water composition, tomatoes are not very nutrient-dense. Their high moisture dilutes potential benefits from vitamins and antioxidants. Rabbits easily get the needed fluids from fresh greens and water. Flooding their diet with extra water from fruits can lead to diarrhea.

High Sugar Content

At 2-3 grams sugar per 100 grams, tomatoes are relatively high in natural sugars like fructose and glucose. This gives them a sweet flavor. But excess sugar gets stored as fat in rabbits while contributing minimal nutrition. Over time, obesity-related illness becomes a risk if rabbits eat too many high-sugar foods.

Low Fiber Content

Tomatoes only contain around 1 gram dietary fiber per 100 grams. Yet rabbits require a whopping 25-30% daily fiber intake for healthy digestion. Leafy greens like romaine, parsley, cilantro, kale and hay remain mandatory fiber sources. Tomatoes cannot substitute for these essentials.

Acidity and Toxins

While solanine and oxalates pose minor issues in moderation, tomatoes’ acidic nature remains a concern for ongoing tummy troubles. So limiting them preserves ideal digestive health.

Consider tomatoes more of a “candy” treat to enjoy once or twice a week after establishing tolerance. Rotate them with other snacks like cilantro, mint leaves, basil, strawberries and melon chunks over a weekly schedule for dietary variety. But keep the majority of diet focused on hay, leafy greens and limited pellets to meet all of rabbits’ nutritional requirements.

Can Baby Rabbits Eat Tomatoes?

No, baby rabbits under 12 weeks old should avoid tomatoes. Their digestive systems remain underdeveloped and overly sensitive during the first few months of life.

Maternal milk and hay meet all necessary nutrition requirements at this stage. Once hitting 3-4 months old, baby bunnies can start sampling limited greens and fruits. But wait until at least 12 weeks old before offering any tomato treats.

Key Takeaways: Can Rabbits Have Tomatoes?

Tomatoes make a fine periodic treat for most healthy adult rabbits. But consider them more of a snack than a dietary staple. Follow these tomato feeding guidelines for rabbits:

  • Only feed ripe, red tomato fruits – never leaves, stems or plants
  • Select low-acid tomato varieties and introduce slowly in small amounts
  • Mix with greens and limit tomatoes to 1-2 times per week for variety
  • Monitor stool and behavior, discontinuing tomatoes if any irritation
  • Avoid tomatoes completely for baby rabbits under 12 weeks old
  • Focus the majority of diet on hay, leafy greens and limited pellets for optimum nutrition

Following these tips allows enjoying tomatoes as part of a diverse rabbit diet without safety or health concerns. But hay and greens should still claim the biggest proportions on the daily menu.

Frequently Asked Questions

Can rabbits eat cherry tomatoes?

Yes. Small cherry tomato varieties tend to be less acidic than large slicing tomatoes. Their bite-size portions also make it easier to limit servings. Cherry tomatoes make great treats if fed sparingly 2-3 times per week once accustomed to tomatoes.

Can rabbits eat tomato sauce?

No. While cooked tomatoes themselves pose no harm, commercially prepared sauces often contain onions, garlic, herbs and excess oil or salt unsafe for rabbits. Stick to freshly chopped plain tomatoes to avoid digestive upset or more serious health impacts from these other ingredients.

Can rabbits eat tomatoes with salt?

It’s best to avoid feeding rabbits tomatoes with added salt, butter or oil. These extra ingredients provide no health benefits and pose risks of their own:

  • Added salt encourages fluid retention and can strain kidneys over time
  • Fats and oils lead to obesity, arteriosclerosis and related disorders
  • Herbs and seasonings frequently cause gastrointestinal irritation

For optimum safety and nutrition, give rabbits plain fresh tomato flesh and skip the add-ins. Provide plenty of fresh water to drink as well to dilute trace tomato acids.

What about rotten tomatoes – can rabbits eat those from gardens?

No! Never feed rabbits rotten, moldy produce from gardens or kitchens. Decomposing tomatoes harbor potentially pathogenic bacteria and fungi dangerous to rabbits, including salmonella and listeria. Extreme diarrhea or fatal illness can occur. Always supervise outdoor play and discard aging fruits to avoid accidental consumption and severe reactions.

Can rabbits eat tomatoes daily if they tolerate them well?

No. Regardless of stool consistency, feeding any single fruit or vegetable daily carries risks of malnutrition or toxicity. Daily tomato treats promote unhealthy weight gain, digestive upset, and potential oxalate accumulation. Maintaining a diverse diet with rotating treats leads to the healthiest outcomes. Limit tomatoes to 1-2 times weekly even without obvious sensitivity problems.

So in summary – tomatoes offer some nutritional value but pose risks if fed improperly or in excess. Follow guidelines on amounts, frequency and preparation for safe tomato treat inclusion. But emphasize hay, leafy greens, herbs and limited pellets as the core daily diet to maximize nutrition and health. By monitoring reactions and practicing moderation with these flavorful fruits, both you and your rabbit get to safely enjoy their sweet tomato goodness!
