In fact, they love to eat mint leaves in their diet. Leaves are the favorite parts of the plant for your guinea pigs. 

However, it is not a healthy habit to feed mint leaves to your pet guinea pigs every day. If you serve mint every day, make sure the portion size is very small.

While you serve mint leaves to your cavies, you need to wash the leaves thoroughly under running water to remove all dirt and pesticides.

Can Guinea Pigs Eat Mint Stalks?

Yes. It is absolutely safe for guinea pigs to eat mint stalks in their meals.  

Mint stalks are very soft. So, when you cut up small-sized pieces of the mint stalk and feed it to your cavies, there is no danger of choking. 

However, it is not healthy to feed mint stalks too often to your cavies. It is recommended to feed them mint stalks no more than once or twice a week.

Can Guinea Pigs Eat Mint Stems?

Yes. Mint stems are highly safe for guinea pigs to eat. 

The stems are as tasty and flavorful as the mint leaves and hence, one of the loved parts of the mint to guinea pigs. Stems are closest to the leaves and can be mixed with vegetable salad along with the leaves.

Furthermore, the mint stems are very soft. Just like the stalks, when you give bite-size pieces of mint stems to guinea pigs, they can eat it without the danger of choking.

You can chop a whole stem of the mint into small pieces while preparing the veggie salad for your cavies.

Can Guinea Pigs Eat Mint Roots?

Can Guinea Pigs Eat Mint Flowers?

Yes. Guinea pigs can eat mint flowers, but in moderation only. 

Guinea pigs love mint flowers because of their exotic smell and taste. No wonder the guinea pigs love to eat mint flowers along with the leaves in them.

Mint flowers are good for guinea pigs when you feed them in the flowers in moderation.

NOTE: It is also important to note here that guinea pigs can have allergies from eating flowers. So, before you serve them the mint flowers, make sure your cavy is not allergic to them. 

The best way to find out about the allergies is to feed a small bite of the mint flowers or leaves and check the reaction.

How Much Mint Can Guinea Pigs Eat?

Your cavies might love to eat mint leaves and flowers, but you should never feed them more than 3-5 leaves each time. 

Mint has a low nutritional content which is nowhere beneficial for our cavies. In fact, if cavies eat mint in large quantities on a regular basis, it can be harmful to them.

So, when you feed safe mint parts to your cavies, feed them in moderation (once or twice a week). You can also try mixing the mint leaves or flowers with other vegetables that are rich in nutrients. 

It is also possible to consider mint as a supplement or palate-changing food in our cavy’s diet.

No matter how much they ask for the mint, you must never make mint a staple in their diet.

What If My Guinea Pig Eats Too Much Mint?

Mint is safe for your cavies. But only as long as you are feeding it in moderation to the guinea pigs and avoid the roots in their diet. 

Feeding mint in excess to guinea pigs can give rise to allergic response and discomfort in them.

So, if your guinea pig has eaten too much mint, observe these reactions below:

  • Allergies
  • Constipation
  • Loss of appetite
  • Irregularity in defecation and bowel movement

Solution: If your guinea pig ate too much mint in their diet, don’t wait for them to show these symptoms or suffer the discomfort. Take your guinea pig to the vet immediately.

However, it is always best to avoid feeding mint in excess to guinea pigs.

You can instead try to feed them with veggies rich in Vitamin C and other micronutrients, like, broccoli, cilantro, parsley, spinach, bell peppers, etc.

How Often Can Guinea Pigs Eat Mint?

You can serve mint to guinea pigs twice a week to avoid health problems in them. 

It is clear from the above-mentioned points that overfeeding mint to cavies can lead to several serious health issues. Hence, when you prepare their meal, add no more than 2 leaves of mint each time.

It is your responsibility to control the mint intake of your cavies. They hardly know when to stop eating.

Nutritional Facts of Mint

Before you start feeding mint to your cavies, here we have some interesting facts about the nutrients present in the mint. 

There are TWO major types of mint available in the market for feeding cavies.

1. Spearmint:

Firstly, when you are out in the market to shop for mint in the grocery shop, the most common mint is the spearmint. The nutrients present in the spearmint are different from that of peppermint.

The spearmint has other names as the common mint, mackerel mint, garden mint, and lamb mint. 

As per the U.S Department of Agriculture, 100 g of spearmint contains the below nutrients-

NutrientsContent in 100 g of Mint
Fiber6.8 g
Vitamin A2.7 g
Potassium 458 mg
Calcium199 mg
Folate70 mg
Vitamin C13.3 mg

2. Peppermint:

Peppermint is actually a crossbreed plant between the popular spearmint and lesser-known watermint. It is relatively new in the market and commonly found in Europe and the Middle East. 

The USDA observed the presence of the following nutrients in 100 g of peppermint

NutrientsContent in 100 g of Mint

Health Benefits of Feeding Mint to Guinea Pigs?

Like we mentioned before, mint doesn’t contain high quantities of healthy nutrients for guinea pigs. So, we can’t consider it as a staple for their meals. 

However, the small amount of Vitamin and mineral content in the plant has some health benefits.

1. Improves the Immunity System:

Mint is rich in Vitamin A, the nutrient that improves the immunity of guinea pigs. 

It works on different body organs like the lungs, heart, kidney, and even the reproductive parts and improves their functions by affecting the immune system.

Though present in a small quantity, Vitamin C also supports guinea pigs’ immunity. The immune support of Vitamin C protects cavies from different diseases.

However, the Vitamin C present in both peppermint and spearmint is not enough to support the immune system.

Therefore, we recommend serving mint with Vitamin C-rich veggies.

2. Improves Eyesight:

The high content of Vitamin A in mint is responsible for improved eyesight in cavies. Mint is the best source of Vitamin A for them.

Vitamin A not only improves the vision in guinea pigs but also protects the eyes from different infections.

3. Helps in Digestion and Bowel Movement:

Fiber is important for easy digestion and bowel movement. Mint, being rich in fibers, helps the digestive system of guinea pigs.

When our cavies eat mint along with other fruits and vegetables, they get enough supply of fibers in their bodies to prevent diseases like diarrhea, constipation, etc.

It helps in regular and smooth elimination and, thus, in maintaining good gastrointestinal health in cavies.

A healthy digestive system means better absorption of food in guinea pigs.

4. Prevention of Scurvy

Since guinea pigs don’t produce Vitamin C in their own bodies, they need an outside source of Vitamin C in their diet to prevent scurvy.

Mint might not be a rich source of Vitamin C for cavies, but when you add mint with other veggies, they help in preventing scurvy.

5. Delays Aging:

All the nutrients present in the mint, including Vitamin C, play important roles in delaying premature aging in guinea pigs.

As Vitamin A prevents diseases in cavies and improves their immunity system, their bodies become strong. Vitamin C prevents the free radicals from affecting the body cells.

Together the nutrients prevent early aging.

6. Protects Guinea Pigs from Bladder Stones:

Potassium is yet another helpful nutrient in the mint that helps in preventing painful bladder stones in guinea pigs.

Bladder stones are a common and painful ailment for cavies. To make sure that your pet doesn’t develop the stones, you can always feed mint in moderation. 

It helps your cavies to maintain a healthy level of potassium in their bodies.

7. Improves Brain Function:

Experts believe that mint contains the ability to improve brain function in cavies.

Some of the nutrients like Vitamin A increase the brain’s alertness and memory retention power.

As we know, the brain is responsible for most of the body functions in an animal. Plus, a healthy functioning brain indicates a healthy animal. 

So, by improving brain functions, the mint nutrients help guinea pigs maintain a healthy life when fed in moderation.

Health Risks of Feeding Mint to Guinea Pigs

Eating mint on a daily basis can be harmful to guinea pigs, leading to health issues.

Here are some of the risks associated with overfeeding of mint to guinea pigs:

1. Development of Bladder Stones and Urinary Troubles

The calcium content of mint is quite high. Though it is an essential nutrient, too much calcium can be harmful as well. 

When you feed mint in excess to your cavies, the calcium in it crystalizes and changes to bladder stones. It might not be life-threatening, but passing the stones can be very painful.

Mint is high in both sodium and calcium.

Excess nutrients like sodium and calcium can cause several health problems like bladder stones, urinary troubles and even harm the development of bladders in cavies.

2. Immunity Damage and Poisoning from Pesticides

Pesticides present in peppermint and spearmint can cause severe damage to cavies. It affects their immunity and digestive system. 

The best way to avoid pesticides in mint is to either buy organic mints from the market or grow fresh mints in your garden. 

Pesticides and excess calcium can also affect the digestive system of our cavies. It often leads to constipation, diarrhea, and similar problems alongside poisoning.

3. Toxicity from Vitamin:

The high Vitamin A content of mint might be useful for developing immunity, but excess Vitamin A can be toxic for guinea pigs.

Hence, it is best to provide them with mint in moderation for a healthy diet.

Toxicity from Vitamin A or Hypervitaminosis is an uncommon yet severe health condition in cavies.

Cavies with Hypervitaminosis show symptoms like dry and scaly skin, lethargy, and rough and brittle fur.

If your cavies are showing any of these symptoms, you should take them to a vet immediately and remove them completely from their diet.

4. Allergic Reactions:

As mentioned earlier, guinea pigs can show symptoms of serious allergic reactions when they eat mint. 

It doesn’t mean that your guinea pig will be allergic to mint. But if they show allergic reactions, you must take them to the vet immediately.

Rosemary is well known as a cooking herb with an exotic aroma among us, humans, 

The presence of antioxidants in rosemary helps in immunity improvement in cavies.

This species of plant has other benefits as well. It helps in scurvy prevention and purifies the guinea pig blood.

What Kinds of Mint are Toxic to Guinea Pigs?

Pennyroyal is a toxic mint plant for our cavies. Though most of the locally available species under the mint family are more or less safe for feeding guinea pigs, you can’t feed pennyroyal.

Two categories of Pennyroyal plants are available around us-

Both the plants are equally harmful to guinea pigs. You must avoid feeding both to your cavies.

Since they both have similar uses, it is easy to get confused while buying mint from the market. 

To distinguish between the two, the American Pennyroyal is commonly called the mock or false pennyroyal, and the European is known as squaw mint, mosquito plant, or simply pudding grass.

If you are still unsure, here is a piece of brief information for Pennyroyal identification.

Identifying Pennyroyals

You can distinguish between the American and European Pennyroyal by their flowers.

While the European pennyroyals have lilac-colored flowers with a strong spearmint fragrance, the American Pennyroyals have blue flowers. 

They even have different types of leaves. The leaves of European Pennyroyals are orbicular or round-shaped. The American Pennyroyals, however, have erect and slender leaves.

Suggestion: Don’t try to identify them by crushing the flower or leaves. Both the plants have a strong minty smell.

How to Feed Guinea Pigs Mint?

When you feed mint to your guinea pigs, remember the below points before buying and preparing the meal:

  • Always serve them fresh mint,
  • Purchase either spearmint or peppermint only, and 
  • Avoid feeding wild mint

Once you have purchased fresh mint for your cavies, follow the below steps to prepare a healthy meal with mint in it.

Step 1: Thoroughly Wash the Mint Under Running Water

Washing the mint thoroughly under running water is important to remove all the dirt and chemicals from it. 

The fresh mint you buy from the market is likely to have dirt and pesticides. Washing it makes the mint safer for cavies.

Step 2: Chop Mint into Medium-Sized Pieces

When you prepare a meal for your cavies with mint in it, make sure you are not adding too many mint leaves.

Pluck 1-2 leaves at a time and chop them up into medium-sized pieces.

Sprinkling medium-sized pieces of mint over the veggies salad improves the smell of the meal.

While it makes the food flavorful, the small quantity ensures that it is never harmful to your cavies.

Step 3: Mix Mint Leave Pieces With Veggie Salad

Your cavies might love mint in their meal, but it is not healthy to serve the mint leaves alone. It is always best to sprinkle small pieces of chopped mint leaves over their veggie salad.

Timothy hay is a staple for cavies. You can also try adding chopped mint with the hay to increase the flavor.

Step 4: Serve in Clean Plate

The final step of feeding mint to your cavies is serving. After you have prepared their veggie salad with mint, serve the salad on a thoroughly washed, clean plate.

It helps in avoiding germs.

Warning: Your duty as a cavy owner doesn’t end with feeding a healthy meal to your pet. Once they finish their meal, you need to clean their cages thoroughly.

Make sure there are no leftovers in the cage. An unclean cage with food leftover often attracts flies, bacteria, and even rats. It is harmful to the guinea pigs.
