Calories are the amount of energy that a rabbit’s body releases.

This process occurs when they digest food.

Diets that are high in calories aren’t what your rabbit needs.

Their body will only store the rest of them as fat.

As a result, cucumbers can be an ideal snack for your bunnies

You may give cucumber slices to your bunnies as treats.

#2: Refreshes your bunny

Rabbits are prone to heat stress.

Temperatures exceeding 60-65°F (15-18°C) aren’t good for them.

They provide great hydration to your bunnies.

And munching it gives a cooling effect to their senses.

Especially in summer or during warm weather.

A rabbit’s diet relies on fiber.

They need lots of it.

And great amounts of fiber are present in cucumber skin.

The skin contains at least 60% more fiber than the flesh.

Plus, it’s an insoluble type of fiber.

Rabbits need fiber that water can’t dissolve.

This is essential in maintaining smooth and healthy gut movement.

It prevents your bunnies from digestive issues like constipation.

Trivia: Rabbits like to lick their fur. And indigestible fiber helps reduce hair buildup in the stomach.

#4: Seeds are safe to eat

Unlike apples, cucumber seeds are non-toxic.

It’s another part of the fruit that is rich in nutrients like:

  • Iron.
  • Zinc.
  • Sodium.

Silica also strengthens connective tissues in the following:

  • Bones.
  • Muscle.
  • Tendons.
  • Cartilages.
  • Ligaments.

#9: Contains 0 cholesterol

Rabbits Are Prone To Obesity

Unfortunately, rabbits are prone to obesity.

This may arise when you feed them treats that are high in:

  • Fat.
  • Sugar.
  • Cholesterol.

Moreover, an unhealthy diet speeds up the development of rabbit diseases like:

  • Hypertension or high blood pressure.
  • Hypercholesterolemia or high levels of bad cholesterol.
  • Cardiovascular diseases such as arrhythmia (irregular heartbeat).

Cucumbers have anti-inflammatory properties like antioxidants.

Antioxidants protect your rabbit’s cells and tissues against damage.

This prevents their body from inflammation responses.

Moreover, antioxidants can help treat bladder dysfunctions in rabbits.

#11: Helps prevent overgrown teeth

A rabbit’s teeth grow day by day. 

And it’s non-stop.

Your bunny’s incisors grow up to 0.07-0.09 in (2 – 2.4 mm) every week.

These are their 4 front teeth in the upper and lower jaw.

A rabbit’s teeth are perfect for grinding coarse or hard food.

And cucumber skins are crunchy.

They help trim those bunny teeth down.

Since cucumber skins are fiber-rich…

Rabbit eating cucumber – 7 dangers

#1: Causes diarrhea

Constant cucumber feeding may cause diarrhea in rabbits.

But contrary to popular belief…

The cucumber’s high water content isn’t the culprit.

According to a study, the causes of diarrhea in rabbits are the following:

  • Stress.
  • Antibiotics.
  • Bacterial infections.
  • High-carbohydrate and low-fiber diet.
  • Toxin ingestion from poisonous plants.
  • Metabolic disorders like true diarrhea (liquid poop).

Furthermore, rabbits have higher water intake than other mammals.

Thus, diarrhea associated with cucumber intake may happen due to:

  • Substituting cucumber for hay.
  • Stomach reactions due to first-time feeding.
  • Toxins (i.e. pesticides) in the cucumber skin.

As a general rule, a rabbit’s diet must consist of at least 80-90% good-quality hay.

#2: Contain insufficient nutrients for a rabbit’s diet

Cucumbers contain lots of nutrients.

But, they may not be able to fulfill the nutritional requirements of rabbits.

Here’s a comparison of a cucumber’s nutritional contents vs a rabbit’s dietary requirements:

ContentValue per 3.5 oz (100 g)Minimum dietary requirements for rabbits per 3.5 oz (100 g)
Iron0.28 mg3 mg
Magnesium13 mg30 mg
Potassium147 mg600 mg
Vitamin A105 IU1000 IU

Thus, it’s best not to rely on your rabbit’s diet entirely on cucumbers.

#3: May lead to weight loss

Cucumbers may supplement the nutrients in your rabbit’s daily intake…

But they aren’t the second-best alternative to hay.

Cucumber substitution may result in weight loss and malnutrition.

Furthermore, be cautious of these signs of malnutrition in your rabbits:

  • Rough or dull coat.
  • Lethargy or lack of energy.
  • Prominent ribs, backbone, and pelvis.
  • Hollowness between the ribs and the abdomen.

Note: Check your rabbit’s weight from time to time.

This helps you keep good track of their health.

#4: High amounts of vitamin C

Vitamin C is an important nutrient for your bunnies.

It helps repair and maintain the connective tissues in the body.

And feeding cucumbers may benefit them.

However, rabbits can already produce vitamin C in their liver.

That said, rabbits may still need vitamin C supplements.

Especially when they’re suffering from heat stress and other diseases.

But too much cucumber intake may result in kidney damage in rabbits.

#5: Affects rabbit poop quality

Cucumber flesh is low in fiber.

Even with the skin on, your rabbit gets 3% of fiber from eating it.

In comparison, rabbits need at least 30-35% of high fiber from hay alone.

According to a study, a low-fiber diet affects the nutrient contents of rabbit poop.

Dietary fiber in rabbits is crucial in their digestive system.

It has a direct effect on the particle separation in a rabbit’s gut.

Meanwhile, fiber nourishes your rabbit’s cecotropes.

Cecotropes are rabbit poop that contains vitamins that the body needs.

Bunnies munch on them straight from their anus.

So, it’s important to know what nutritional value your bunny gets from what they eat.

Or what you feed them even as a treat. 

#6: May cause allergic reactions


Rabbits can get food allergies, too.

It may be difficult to assess this matter on your own.

Because most of the time, food allergy points to your rabbit’s genetics.

When rabbits inherit this trait…

Their body may develop reactions to certain food they eat.

Some previous health records from your bunny’s ancestors are a huge help.

However, you can also watch out for these common allergy symptoms:

  • Diarrhea.
  • Dull coat.
  • Constant feet licking.
  • Itching and scratching.

Fur loss is also another symptom of food allergy.

But it takes a while to notice this.

Moreover, cucumbers may cause allergies in them. 

But it’s vital to know that food allergies are unique in every bunny.

It’s tricky which food is good for them or not. 

However, you may request a blood test at your vet.


“Prevention is better than cure.”

#7: Causes gastric dilation

Or in other terms, bloating.

Unfortunately, this is a serious condition that most rabbits suffer from.

Gastric dilation occurs if something blocks your bunny’s gut.

It could be hair buildup or foods that aren’t tummy-friendly.

If you feed cucumbers in large amounts…

Chances are, your rabbit’s stomach will have a hard time digesting it.

Since they can’t vomit, these low-fiber foods stay in their gut.

Plus, their digestive tract produces gas and fluids.

So, your bunny processes a lot of contents in their belly other than food. 

This causes their abdomen to bloat and looks enlarged.

Sometimes, it looks like a balloon inside their tummy.

But, this may get painful for them as time goes by.

In severe cases, bloating messes up their blood flow.

BONUS: Cucumber skin contains chemical residue

Cucumbers have natural wax on their skin.

But commercial markets add another layer of synthetic wax to them.

This is to ensure that they’re in good shape before hitting the shelves.

However, this poses a threat to you and your rabbits if eaten.

Cucumbers have high levels of pesticide residue.

According to EWG, this fruit ranked 18th spot in 2022.

The Environmental Working Group refers to this list as the Dirty Dozen.

This is another vital thing to consider for your bunny.
