Can Rabbits Eat Zucchini?

Can rabbits feed on zucchini? Yes, they can!

Although zucchinis are not as essentially associated with rabbits as carrots or hay, people all over the world enhance their rabbits’ nutrition with them.

As part of a rabbit’s balanced diet, zucchini provides extra nutrition and variety to their mealtimes. Rabbits can eat zucchini, and some really like it! But unlike any fresh vegetable, zucchinis can’t be part of the rabbit’s main food source.

Wild rabbits survive mainly by grazing in their surroundings, and domesticated rabbits are no different! And an excellent way to feed your pet rabbit is with a hay-based diet that can be enhanced with fresh vegetables.

Reliable rabbit owners embrace the fact that feeding your rabbit with a wide variety of vegetables can help their pets live longer and have healthier lives. But with their delicate digestive systems, knowing what you can serve to your pet rabbit can be a tough one!

In this article, we’re going to clarify whether rabbits can eat zucchini. We’ll also talk about zucchini’s nutrition facts and health benefits, as well as some guidelines you can follow when feeding this vegetable to your rabbit and the right amount they should eat as well.

Rabbits Can Eat Zucchini

Zucchini squash, also known as courgette, is considered safe for rabbits to consume. It is a good addition to a rabbit’s typical diet of fresh hay and clean water.

Add some zucchinis to their diet to provide variety as well as extra vitamins and minerals for your rabbit’s health.

Is Zucchini Safe for Rabbits?

Introducing new foods to your pet rabbit can always be a cause for concern. The traps of rabbits’ intolerances to specific foods can make it a little scary.

The PDSA put zucchini as one of the safest foods to feed to a rabbit as part of its regular supplement of fresh vegetables. So at first look, it seems as though it could be an excellent new addition to your rabbit’s mealtimes!

Adding fresh vegetables to a rabbit’s diet can raise their meals to another level and make it more interesting and varied, as well as the nutritions they can benefit from.

Zucchinis carry a whole multitude of nutrients and a good amount of potassium (about 262 mg per 100g).

Potassium is a vital ingredient to your rabbit’s nervous system, and any addition of fresh vegetables can be helpful to your rabbit’s digestive system.

A small addition of fresh vegetables to your pet rabbit’s meal can go a long way, and zucchinis are no different. Just keep in mind to give your pet rabbits zucchini slowly for the best results.

But are there any cases when zucchini might be bad for your pet?

Can Zucchini Be Bad for Rabbits?

While most rabbits can easily digest zucchinis, some will find that it doesn’t sit well with them.

Zucchini carries a high amount of sugar which can upset a rabbit’s digestive stability. Diarrhea is a common symptom. So, if your rabbit produces a runny stool, it is a sign that you should remove zucchini from their diet.

As for adding new foods to your pet rabbit, they should be introduced gradually to enable your pet’s digestive system to adjust to it. That suggests adding anything new, such as zucchini, must be served in smaller quantities.

This is critical because it can trigger diarrhea which can be serious in rabbits, and an immediate shift in diet can upset your rabbit’s tummy.

Start from a small amount then gradually increase the serving over the period of several days. If you see any new issues, remove the zucchini completely and keep an eye to your rabbit’s condition. Always reach your vet if diarrhea still persists.

So, feeding your pet rabbit with zucchini sensibly won’t create any harm to your rabbit, does it actually do him any good?

Zucchini Facts

Being related to the squash family, zucchini is linked to pumpkins and butternut squash. It is labeled as a fruit by botanists but is more frequently used in cooking. Its name derives from the Italian term “Zucca”, meaning pumpkin or squash.

Zucchini’s nutritional value matches a fruit more than a vegetable. It also carries a high amount of sugar and is rich in vitamin C. Its calorie counts are 66% carbohydrates, 18% protein, and 16% fats – making it a fair alternative for a rabbit’s diet.

Health Benefits of Zucchini for Rabbits

Adding zucchini to your rabbit’s diet can help to compare the nutrient consumption from hay. Plus, rabbits always enjoy having a wider choice of foods to eat!

Zucchini is an excellent food that carries a high amount of nutrients. It is high in water and fiber content but is low in calories. If your rabbit is encountering digestive problems, a slice of zucchini can provide relief. Let’s take a detailed look at the benefits:

High in Nutrients

Zucchini is loaded with potassium. This element is very beneficial to a rabbit’s digestive system. In fact, not having much of this has been linked to muscular dystrophy in rabbits, as stated in The Journal of Nutrition. Other nutrients in a zucchini incorporate:

  • Vitamin A
  • Magnesium
  • Manganese
  • Vitamin K
  • Vitamin B
  • Folate
  • Phosphorus
  • Thiamine

In smaller amounts, zucchinis also carry:

  • Iron
  • Zinc
  • Other B vitamins

High Water and Fiber Content

Rabbits require a fiber-rich diet to produce healthy digestion. Zucchini is an excellent source of fiber if given by a gram per one cup.

On top of its nutritional content, zucchini also carries plenty of water. A cup of this fruit consists of more than 90% water. If you want your pet rabbit to keep hydrated, a few slices of zucchini can easily balance its diet.

Low in Calories

Because of the high amount of water they carry, zucchinis are also low in calories. This is a piece of awesome news for rabbits, whose minimum caloric consumption should be at about 2.2 calories per gram or about 900 calories per pound. At a standard of 6 pounds, the domestic rabbit should consume about 5,500 calories per day.

It may appear like high numbers. Nonetheless, keep in mind that bunnies acquire the majority of their calories from other vital parts of their diet. 

One whole zucchini only carries 55 calories. That means you don’t have to worry about your rabbit gaining weight. As a reward or snack, your rabbit can surely munch on zucchini while receiving their health benefits, and not destroy its appetite.

Reduce Risk of Heart Disease

According to Food and Nutrition Sciences, zucchini can reduce the danger of atherosclerosis, or heart disease. This is mainly due to the high levels of good cholesterol found in zucchini, which have been connected with lower levels of heart disease.

As a bonus, heart disease has been related to high caloric consumption. Because zucchinis carry low calories, you can be sure they won’t harm your beloved buddy.

How Much Zucchini Should I Feed My Rabbit?

If you observe that your pet rabbit can properly digest zucchini, you can now start adding a handful once per day in addition to their normal diet of hay. Though zucchini contains a lot of water, it is a little sweet, so it is still important not to overfeed your rabbit with it. Always opt on the side of underfeeding your pet rabbit for everything except hay.

It’s all about giving them the right proportions rather than giving them the exact amount. Your rabbit’s diet should mainly be based on hay, and fresh vegetables should serve to be a supplement, not a mainstay.

Though fresh vegetables can and will help make your rabbit’s diet turn into a healthy and nutritious one, they should not make up the majority of their regular diet. For small rabbits, you can feed them with a slice or two, and for larger rabbits, they might enjoy three or four slices only.

Remember, serving them with too many vegetables can cause a digestive problem.

Rabbits are not good at stopping, so be careful not to overfeed them!

Adult or Fully Grown Rabbits

Your pet rabbit is considered adult or fully grown if it is more than 1 year old. Adult rabbits can start consuming zucchini but must still depend on their weight or breed.

You just have to make sure that you’re providing your rabbits other veggies to support variation when it comes to their diet to mimic what they consume in the wild.

If you are about to introduce zucchini to your bunnies for the first time, just give them 15 grams per day, then steadily increase it to 10 grams per week until your pet reaches the normal amount.

Young or Growing Rabbits

Bunnies or rabbits are still considered young or still growing if they are less than 12 weeks old and should not be given any veggies like zucchini.

Bunnies’ gut flora is not yet adapted to absorbing the new food source and could create digestive issues like diarrhea or GI stasis.

Pregnant or Lactating Rabbits

You should not change the diet of a pregnant or lactating rabbit.

After serving them the same amount and type of food for 3 weeks, you may start increasing the number of pellets gradually for the remaining 10 pregnancy days. This should keep on until the first week of lactation.

During pregnancy or lactation, you should only feed zucchini to your rabbit as a supplement to hay and pellet because pregnant rabbits require the most nutritious diet they can get.

How to Feed Zucchini to Your Rabbits

If you’re adding zucchini to your rabbit’s diet for the first time, it’s essential to do so gradually.

Begin with only a few small bites per day, then observe your rabbit closely for symptoms of indigestion. If they appear bloated, lethargic, or having difficulty going to the bathroom, it’s ideal to quit feeding them zucchini right away.

For rabbits that do enjoy eating zucchinis and can digest it very well, you can surely feed it to them raw in any shape. You can also make zucchini “pasta” by peeling off thin layers. This can also slow down your rabbit’s eating!

If you want to add zucchinis into your rabbit’s diet, where do you begin?

In Small Amounts

Due to the rabbit’s sensitive digestive system, all new food should be added slowly. If you change a rabbit’s diet abruptly, this can upset its fragile gut health. Should this fall, your pet may encounter discomfort, irregular bowel modes, changes in mood, or more serious health matters.

Instead, by providing your rabbit with small amounts, its body can easily adjust slowly. Likewise, this will supply your rabbit with some time to determine if it likes the taste of zucchini. If forced, it may reject the new treats altogether.

Slice Thinly

Food that can be eaten easily by your pet rabbit will be more welcomed. The chance of choking will be minimal and it will be easier for your pet rabbit to digest.

You can serve zucchini to your rabbit in thin slices or small cubes. However, this method may take more time for your rabbit to munch. If chewing on the new food is time-consuming, it may reject the zucchini in favor of foods that are easier to consume.

So when slicing zucchinis, make it 1/8 or ¼ of an inch.

Wash Beforehand

Washing zucchini guarantees that there are no bacteria, fertilizers, or chemicals still lingering on its surface. Whether cultivated in your garden or purchased in the store, just like humans, all veggies must be washed before feeding them to your rabbit.

This is due to the toxins found on the surface. While a healthy human body can easily treat most things that are located in commercial foods, a rabbit’s sensitive chemistry may not.

Avoid Giving Zucchini To Juveniles

Raw veggies, such as zucchini, should not be fed to baby rabbits. Particularly, this involves rabbits younger than 2 to 4 months.

All rabbits possess a delicate digestive system. Younger rabbits, however, have more sensitive guts. This is because the gut flora, which is necessary to regulate their diet, is still developing.

Any changes done to their normal diet can create an imbalance in their gut. This will surely lead to a series of health difficulties.

Instead, it’s ideal to wait until your rabbit reaches its maturity. Then, you can provide these treats safely.

As a Treat

Hay and grass should still make the majority of your rabbit’s diet. Serving too much zucchini can leave your rabbit overly stuffed and will be unable to eat the timothy hay and orchard grass it requires. This leads to a low-calorie intake, as well as fiber, and essential nutrients not found in zucchini.

Don’t be deceived by the “awesome” health advantages of zucchini and make it the main element in your rabbit’s diet. Instead, only serve this fruit as a wonderful treat. When served occasionally, it can be a health improvement that can support your bunny’s regular diet.

With Supervision

All rabbits are different and will surely react to foods in different ways. After serving them with zucchini for a week, try to observe them closely for any health and behavior shifts. If it doesn’t display any changes, feel free to continue feeding them with zucchini.

However, common signs of digestive problems include loss of appetite, weakness, and runny stool. If you notice these behaviors, return them to their original diet, and consult your vet as soon as possible. It may appear that you are overfeeding your bunny with zucchini.

Raw vs. Cooked

Zucchinis must always be served raw to your bunny. Rabbits are not able to consume butter, oil, or other ingredients typically applied to prepare zucchini. If accidentally ingested, these additions will surely produce digestive problems.

Even if a rabbit could consume cooked zucchini, its raw equivalent is still excellent. Compared to cooked ones, raw zucchini will provide more vitamins and minerals.

The cooking method destroys or lessens the nutrients found in vegetables and fruits. Roasting, baking, frying, or boiling zucchini will remove the healthy components of your rabbit requirements.

Rabbits are very picky with what they eat, and a raw zucchini is less likely to be appealing than cooked ones. After all, you won’t encounter any wild rabbits that cook anything over a fire. Because of this, it’s wise to serve your rabbit fruits picked straight from the garden or fridge.


Freezing can break down the nutrients found in food the same way that cooking does. It also changes the taste and texture of zucchinis.

For these reasons, don’t ever feed your rabbit with frozen zucchinis. Not only will it damage your bunny’s stomach, but it also carries less nutrition. Even your bunny will surely reject this because of the taste.

Parts of Zucchini to Feed Your Rabbit

Want to know why zucchini is an excellent treat to serve your rabbit? Because all of its parts can be fed to bunnies! The skin, leaves, flesh, flowers, as well as seeds, are all safe for your pet rabbit to consume, making it a handy vegetable indeed.

You should always opt for fresh, organic vegetables that you can feed to your rabbit. Don’t choose anything that’s been treated with pesticides or waxes, as these can quickly upset their delicate digestive system. It’s also ideal to avoid frozen and cooked zucchinis, as both will be hard for your pet rabbit to digest.


You surely don’t have to go through the trouble of peeling this fruit as it’s safe.

In fact, it would be better to leave the skin on a zucchini. The same with most fruits and vegetables, the skin carries several nutrients that are great for your rabbit’s health.


The leaves of zucchinis are large, with sharp edges, so be sure to shred or cut the leaves into smaller, more edible sizes.

If your rabbit loves eating zucchini, the leaves can be a perfect addition to its diet. Just be sure to wash the leaves thoroughly before serving them to your beloved bun.


Zucchini flowers are also safe to feed to your rabbit. The flowers are golden, with a bell pattern and petals that look like a star.

You may see that there are two types of flowers found on a zucchini. One is a bit bigger and placed at the end of the plant, while the other one is smaller and grows directly on the stem. These indicate if a flower is a female and male, respectively. And both types are safe for your rabbit.

Zucchini flowers are an exceptional treat that you can give to your rabbit. The only caveat is that they can be expensive.

The flowers of zucchinis are very delicate, making them difficult to store and transport. However, if you have access to a zucchini plant where you can harvest flowers, then feel free to feed it to your rabbit. 

Same with the leaves, just be sure the flowers are fresh and washed thoroughly.

Risk of overfeeding zucchini to rabbits.

Uneaten Caecotrophs

Uneaten caecotrophs occur if a rabbit is fed that carries a low amount of fiber or in contrast, overfeeding them with foods that carry an excessive amount of water.

Feeding zucchini alone to your pet rabbit could not meet their daily fiber requirement, zucchini should only be served in small amounts as an addition to a hay-based diet.


Overfeeding your pet rabbits with zucchini could also direct to diarrhea due to fiber deficiency.

Your rabbit’s diet should consist majorly of hay and pellets, vegetables like zucchini should only be served in small amounts because it doesn’t provide enough fiber.

If your rabbit is experiencing diarrhea, bring your rabbit to a veterinarian as soon as possible because it is fatal for them.

Gastrointestinal Stasis

Gastrointestinal stasis is also produced by a diet that is low on fiber and consuming too many carbohydrates.

If you accidentally overfed your pet rabbit with zucchini, it could lead to an irregularity in your rabbit’s gut flora and slow down the flow of food through the GI tract.

If you speculate that your rabbit might be experiencing GI stasis, promptly bring your rabbit to a veterinarian before it leads to an organ failure and death if not treated immediately.

When to Stop Feeding Zucchinis to Rabbits?

Young rabbits possess a delicate stomach so it’s a better idea not to feed them any other food except hay. But after 12 weeks, you can begin serving them veggies in small amounts(about 15 grams).

If you see any digestive discomfort or shifts in your rabbit’s stool, the advised action is to always exclude any other food except hay.

Your rabbit might be consuming too many veggies and other useless stuff and is requiring fiber in its diet. Turning their diet to hay will surely make their problems fixed.

But as always, it’s still ideal to consult your veterinarian as soon as possible when you see any odd turns in your rabbit’s behavior or if your rabbit has any alterations in its eating habit.

Keep in mind that most digestive discomfort could drive to GI stasis, which is fatal to rabbits.

Final Thoughts

Rabbits can eat zucchini and several rabbits will surely enjoy eating small quantities of this vegetable as part of their well-balanced diet.

When your pet bunny is still in the earlier stages of its life, you’ll naturally be worried about how its young stomach will adjust to different foods. As prescribed, introduce any vegetables very slowly at 2-4 months of age.

If your pet bunny finds it hard to adjust to a new food, it’s always best to leave it until their later life. Add it gradually and carefully to your bun’s diet.

As we discussed earlier, you should observe your rabbit for any shifts in behavior following a dietary modification.

Zucchini is an exceptional addition to your rabbit’s diet and is totally safe for them to eat, but introduce it to their diet slowly. If you have access to organic ones then give it to them, if none, try planting some in your garden this year to provide to your bunnies!
