Can Rabbits Eat Spinach?

As a rabbit owner, you might be wondering if your furry friend can safely enjoy spinach.

After all, these leafy greens are packed with vitamins and nutrients, making them a healthy choice for humans.

Can rabbits also benefit from spinach in their diet? Let’s find out.

Can Rabbits Eat Spinach?

Rabbits love spinach.

They will happily nibble away on spinach leaves, spinach stems, flower spikes of spinach that have been allowed to bolt, and maybe even the roots if they are hungry enough.

But spinach should only be a small part of your rabbit’s diet.

Spinach contains many essential vitamins and nutrients but is also high in oxalates, which can cause health issues if consumed in large quantities.

So, while your rabbit can enjoy this green treat, it’s important to moderate the serving size and mix it with other leafy greens to ensure a well-rounded diet.

When feeding spinach to your rabbit, always wash the leaves thoroughly to remove any dirt or pesticides.

Offering a variety of leafy greens can provide your pet with the nutrients they need to thrive, without relying solely on spinach. Remember, moderation is key, and a little spinach goes a long way in keeping your rabbit healthy and happy.

Despite its numerous health benefits, spinach should be fed in moderation. This is due to its high oxalate content, which can contribute to the formation of urinary stones and bladder sludge in rabbits. To avoid these health issues, it is recommended to limit the intake of spinach to 1-2 times a week, along with a variety of other leafy greens.

Spinach Is a Highly Nutritious Food (for Rabbits too)

There is a lot to like about spinach.

Spinach is a good source of calcium, iron, and magnesium. It packs a punch with some plant compounds that the rabbit’s body turns into vitamin A, riboflavin, vitamin B6, and folic acid.

The fresh portion of spinach is also low in sugar, making it an ideal vegetable for maintaining your rabbit’s weight.

Spinach is a Good Source of Nitrates

Nitrates are the building blocks of nitric oxide.

In rabbits, as in people, nitric oxide helps keep arteries flexible and open so the rabbit can hop away to safety when needed.

These are the same nitrates that are found in a product made from another plant in the spinach family, SuperBeets. Beet leaves are also a good food for your rabbit.

Spinach Contains Fiber

In human diets, it contains enough fiber to make a difference.

In a rabbit’s diet, spinach does not contain enough fiber to compete with hay or woody plants.

Rabbits need fiber to keep the hair they lick off themselves from accumulating at the pit of their stomachs.

Rabbits cannot cough up hairballs, so the accumulated hair can cause a potentially deadly condition known as woolblock or gastrointestinal stasis.

Rabbits also have a unique, if somewhat icky, two-step digestive process that involves eating their poops after they pass through their colons the first time.

Exposing soft poops to air activates bacteria that transform fiber into healthy fatty acids that don’t occur in plants.

But there is a reason you should not give your rabbit a lot of spinach. That is because spinach is high in oxalates.

Potential Risks of Feeding Spinach to Rabbits

While spinach provides essential nutrients for your rabbit’s health, it also has some potential risks.

One of the main concerns is its high content of oxalates, also known as oxalic acid.

These compounds can bind to calcium and other minerals like magnesium and iron, reducing their absorption in your rabbit’s body.

Over time, this may lead to bladder sludge or the formation of bladder stones and urinary stones in your rabbit’s urinary tract.

Additionally, feeding too much spinach to your rabbit can cause imbalances in its calcium to phosphorus ratio.

Spinach is high in calcium, and an improper ratio in your rabbit’s diet may contribute to health risks such as decreased bone density and dental issues.

You should be aware of the potential presence of pesticides in spinach, especially if it is conventionally grown.

Consuming excessive amounts of pesticide residues can be harmful to your rabbit. To minimize this risk, you may choose to feed your rabbit organic spinach or thoroughly wash the spinach before feeding.

Another concern with spinach is the possibility of overfeeding, which can be harmful to your rabbit. Following proper feeding guidelines and balancing spinach with other leafy greens like watercress is essential to provide your rabbit with a varied and balanced diet.

Lastly, it’s worth noting that some greens, like rhubarb, should not be fed to your rabbit due to their high oxalic acid levels. However, spinach can still be fed in moderation as long as you take these precautions into consideration.

Unlikely (but Possible) Problems of Feeding Your Rabbit Too Much Spinach

It is possible for rabbits to eat too much spinach.

The most likely source of problems would be too much oxalate. Symptoms could include any or all of the following.


Calcium oxalate crystals are sharp. Rabbits that eat dry spinach could experience irritation of their mouths and lips, which causes drooling.

Redness Inside the Mouth

Oxalate crystals can bruise and scrape the soft tissues of a rabbit’s mouth and palate. They can even get inside the rabbit’s nose.

This can result in redness in the mouth.

Tummy Tenderness

If a rabbit had nothing to eat except spinach, it could get a serious tummy ache.

This would be the result of irritation to the lining of the stomach.

You are highly unlikely to witness this problem unless you fed your rabbit a bag of spinach. A few leaves will not do this.

Reduced Urination

Kidney stones cause painful urination or reduced urination.

A rabbit that has kidney stones may urinate outside its litter box. This is a problem that is not related to urinating to mark territory or exerting dominance over other rabbits.

Oxalate-caused kidney stones take weeks or months to develop. This problem only comes up when rabbits are given a combination of high-oxalate foods such as spinach and alfalfa, spinach and beet greens, or spinach and green beans.

And they would need to be getting these combinations of foods every day.

In some ways, spinach is a bigger problem than nibbling on houseplants.

Some houseplants, such as dieffenbachias, dumbcane, philodendrons, and begonias, are much higher in oxalates than spinach.

But they are so high in oxalates that they cause immediate discomfort in rabbits.

Rabbits will only eat toxic houseplants if they are very hungry. But they will eat tasty fresh spinach without any immediate pain.

Safe Way to Feed Spinach to Your Rabbit

The safest way to feed your rabbit spinach is also a way to have fun feeding your pet.

Pick out some small, tender, juicy leaves of spinach from the bunch or from the bag. Feed them to your rabbit by hand, one at a time.

Three or four leaves at a time is enough. Ten or so should be the upper limit.

Special Considerations for Different Rabbits

When it comes to feeding spinach to your rabbits, it’s crucial to understand that different types of rabbits might have specific dietary needs.

Spinach can be fed to rabbits, but as previously mentioned, it should be given in small amounts due to its high oxalate content.

Baby Bunnies

Baby rabbits have delicate digestive systems. Introducing spinach to their diet might upset their digestion.

Ensure that you first establish a healthy diet for bunnies, mainly consisting of alfalfa hay and pellets, before introducing small amounts of spinach when they reach around 12 weeks old.

Pet Adult Rabbits

For your pet rabbits, variety is key. Along with other leafy greens and vegetables, you can include spinach in their diet, strictly limiting the frequency to 1-2 times a week.

Providing a mix of other leafy greens ensures that your pet rabbit gets the necessary nutrients without an excessive intake of oxalates.

Wild Rabbits

Wild rabbits typically have a different foraging pattern than pet rabbits. They eat various plants, including some spinach, if it’s available in their environment.

However, their diet is primarily composed of grasses and other natural vegetation. As such, spinach intake is less of a concern for them.

Seasonal Considerations

Besides the type of rabbit, the season also plays a role in feeding spinach.

For example, feeding your rabbit spinach in the fall instead of spring or summer helps avoid high oxalate content. Winter is generally unfavorable for spinach consumption.

What About Protecting Spinach In Your Garden?

When I was raising rabbits, my mother also had a big bed of spinach and Swiss chard (in the Commonwealth, this vegetable is called silverbeet).

My rabbits only got into it once, and I got them back inside their hutch before my mother even found out.

But you don’t want your rabbits to get into your spinach patch and eat down all the spinach you are raising for yourself.

Here are three ways to prevent this problem:

  • Place a rabbit-proof fence around your garden. Chicken wire keeps even baby bunnies out, if your fence is at least 3 feet (about a meter) tall.
  • Sprinkle a non-toxic powder around your spinach patch that rabbits don’t like. Bloodmeal, garden lime (the soil additive, not the citrus fruit), and sulfur work. So does mountain lion urine, but you might like that odor.
  • Grow spinach indoors, or in a greenhouse or cold frame.

Frequently Asked Questions About Feeding Spinach to Rabbits

Q. How often can rabbits eat spinach?

A. Rabbits can eat up to handful (an ounce, or about 30 grams) of dark leafy greens, including spinach, every day. Most of their diet should be hay.

Can rabbits eat spinach every day?

No, rabbits shouldn’t eat spinach every day. Limit spinach consumption to 1-2 times a week to prevent potential health issues caused by excessive calcium and oxalates.

Q. Which vegetables can rabbits eat with spinach?

A. Kale, turnip greens, mustard greens, cabbage leaves, radish leaves, celery leaves, and Romaine lettuce are good choices for rabbits.

Remember, they should get about an adult handful (1 ounce, or 30 grams) of all of these vegetables together every day, not a serving of each of these vegetables every day.

We can’t say it too often: Most of your rabbit’s diet should be hay.

Q. Can rabbits eat cooked spinach?

A. Cooked spinach is not toxic to rabbits, but fresh spinach tastes better for them.

You should never give a rabbit any vegetable with oil, bitter, cheese, eggs, or bacon bits added to it. Fresh, tender veggies are ideal.

Q. Don’t rabbits swallow dirt when they eat spinach fresh from the garden?

A. You wash the spinach you harvest from your garden. Your rabbit can’t. Your rabbit swallows anything that is on the spinach plant along with the spinach itself.

That includes dirt and insects.

Q. Will my rabbit get sick from eating bugs on spinach from my garden?

A. Some bugs on spinach are not harmful. Aphids that are stuck to the underside of spinach leaves, for example, are even an important source of vitamin B12.

Slugs, on the other hand, can be very toxic for rabbits. Some varieties of slugs can make people very sick if eaten and can kill rabbits that eat them.

Q. What should I do if my rabbit gets into my spinach plants and eats a lot of them?

A. If your rabbit does not seem sick, then all you really need to do is to make sure it does not get into your spinach patch again!

You also should withhold any other leafy green vegetables for two or three days.

For rabbits, the best natural food is dry, clean, fresh timothy hay and timothy hay pellets. Make sure your rabbit has unlimited access to clean, fresh water.

Together, hay and water support rabbit health.

If your rabbit has eaten spinach that has been sprayed with pesticides, veterinarians recommend you take the following steps.

  • Stay calm. Make sure your rabbit does not eat even more of the plants you have sprayed.
  • Identify the pesticide. Find the bag or container, so you can take it with you when you take your rabbit to the vet. This way, your vet will quickly know what to do.
  • Take your rabbit to the veterinarian as quickly as possible.

If your rabbit gets pesticide on its fur, wipe it off with a clean, moist cloth and throw the cloth into the garbage. Do not give your rabbit a bath.

Baths are a scary experience for rabbits and can cause them to go into shock.

Keep any rabbit that has been exposed to pesticides separate from your other rabbits until you know they are not contaminated with dust that can affect the rest of your pets.

Don’t watch and wait if you think your rabbit may have been poisoned. Seek help immediately. If you wait, treatment may not be possible.

Q. What are the best ways to prevent problems with rabbits and their food supply?

A. Take control of your rabbit’s food supply.

Make sure your rabbit has an unlimited supply of hay. Placing hay in a feeder from which it grabs one stem or leaf at a time is ideal.

This is a fun activity for your rabbit, and it also keeps your rabbit from getting into trouble with eating too much or eating the wrong plants.
