But that doesn’t mean you can give your guinea pigs as much basil as they want. You have to control the amount you give your guinea pigs. Otherwise, it’ll seriously mess up their health in the long run.

Let’s dive into the details and see how much basil is safe for guinea pigs and how you can give it to them without any problem.

Is Basil Good for Guinea Pigs? 

Yes, for the most part, basil is good for guinea pigs. This herb is a rich source of many essential nutrients. For instance, its high in vitamin C, vitamin A, antioxidants, zinc, and magnesium. All these nutrients are vital for guinea pigs’ health.

So yes, basil is a tasty AND healthy snack for piggies.

Here’s why:

1. Packed With Phytochemical and Antioxidants

Basil is a rich source of antioxidants and phytochemicals. These two nutrients are very beneficial for guinea pigs.

This herb contains quercetin, apigenin, caffeic acid, and luteolin. (Fancy, names right?) Well, they’re antioxidants. And they’re important because they help protect your fur babies’ cells from damage. Free radicals can damage cells. They make them weaker and less effective. Antioxidants help to stop this from happening.

Antioxidants scavenge these free radicals and make sure they don’t damage the cells. This process is called “oxidative stress.” It’s important for guinea pigs because it helps them stay healthy and avoid diseases.

2. Can Help With Digestion

Basil can also help with digestion. This herb is a good source of fiber, which is awesome for guinea pigs. Fiber adds bulk to the stool and makes it easier to pass. It also prevents constipation, which is a common problem in guinea pigs.

3. Calming Effect

Basil has a calming effect on guinea pigs. This herb contains linalool, which is a compound that has a calming effect on animals. This compound can help to reduce stress and anxiety in guinea pigs.

So yes, if you’ve noticed that your guinea pig is feeling stressed, you can give them some basil to calm them down.

4. Improves Eyesight

Your guinea pig needs good eyesight as much as you do, and basil can help with that too. This herb is a good source of vitamin A, which is essential for vision. Vitamin A helps to prevent night blindness and protect the eyes from damage. And yes, you can also expect improved vision in your guinea pigs.

5. Scurvy Protection

One of the top reasons for giving guinea pigs basil is that it helps to prevent scurvy. Scurvy arises from the deficiency of vitamin C, a nutrient piggies don’t make of their own. 

So they have to get it from their diet. And basil is a good source of this nutrient. Vitamin C is essential for guinea pigs as it boosts the immune system. It also helps to protect the cells from damage.

6. Low Calorie and Low Fat

Basil is also low in calories and fat. This herb contains only 23 calories per 100 grams. It’s also poor in fat, with only 0.64 grams of fat per the same quantity size.

That makes basil a thoughtful choice for all guinea pigs, including overweight ones. Actually, basil can help obese cavies lose weight without compromising their nutrient intake.

Risks to Consider When Feeding Basil To Guinea Pigs

a decision tree about guinea pigs eating basil
Use this to help you figure out if you should feed basil to your little friends.

Even with all the above benefits, there’s also some risks when feeding your guinea pigs basil. That includes overfeeding, pesticides, and digestion issues. But if you follow the feeding guidelines, basil should be entirely safe for your pet. 

Let’s look at these risk factors;

1. Overfeeding

It’s easy to overfeed herbs to your piggies. Like who can keep track , right? But you really need to.


Because guinea pigs are prone to bladder and kidney stones. They’re caused by a buildup of minerals, including calcium. And too much calcium in their diet can cause these stones to form.

And guess what basil has a lot of…yep, calcium.

You see, guinea pigs need a balanced diet.

Too much of one nutrient can cause health problems for your fur babies. So you really need to watch how much basil you’re feeding your piggies. A good rule of thumb is to offer no more than one leaf (or half a leaf) once or twice a week.

(Or once a month…or none at all, if your piggies are prone to bladder and kidney stones.)

Plus, too much of this herb for your guinea pigs can lead to digestive problems like bloating, gas, and diarrhea. So only give your guinea pigs basil in moderation.

2. Pesticides

It’s possible that pesticides have been sprayed on the basil to protect them from pests and diseases. And these farm chemicals can be harmful to your guinea pigs if ingested.

To avoid all that, only give your guinea pigs organic variety. This will ensure that they’re not ingesting any harmful chemicals.

You can even plant a small herb garden in your kitchen or backyard and grow your own organic basil.

3. Digestion Issues

Digestion issues is another reason to be careful when feeding your guinea pigs basil. The fiber in this herb can cause more harm than good to your pet’s gastrointestinal. That’s why you always have to stick to the “rules of the game” when offering your piggy basil.

Is It Common For Pet Parents To Feed Basil To Their Guinea Pigs? 

Yes, it’s actually quite common for pet parents to give their guinea pigs basil. This herb has so many benefits that it’s hard to resist giving it to your beloved pet.

Even so, you should always be careful when feeding any new food to your guinea pig. Some foods can cause some serious digestive issues. Always best to start with a small amount and see how your guinea pig reacts to it.

All these flowers are edible and will not harm your pig. But before you offer any of them to your pet, do the necessary. In other words, only offer well-washed fresh petals and in moderation.

You’re going to need patience to build up your piggies’ love for a new treat. So, if they don’t like basil at first, try again later. With time, they may start enjoying it.

Are Guinea Pigs Allergic To Basil?

But be careful not to use too much. Always wash the herb before you give it to your piggies. Also, try to give them organic basil leaves. That way you know for sure that there’s no harmful chemicals or pesticides on the leaves.

Can Baby Guinea Pigs Eat Basil?

Baby guinea pigs can eat basil. Basil is a good food for them because it has a lot of calcium. This will help their bones and teeth grow strong. Unlike adults, baby piggies (less than six months old) thrive on high calcium hay (like alfalfa) and treats like basil.

How Often Can Guinea Pigs Eat Basil?

If your guinea pig has had stones in the past, it would be best to avoid giving them any foods that are high in calcium (including basil).

How To Forage For Basil

You can find basil in your backyard, at the park, or even in the wild. If you’re foraging for basil, make sure you only pick leaves that look fresh and green. Avoid any that are yellowing or browning as these could be poisonous.

It’s also important to avoid basil that has residues of pesticides. If you’re not sure if the basil has chemical traces, it’s best to avoid it.

Once you’ve gathered the herb, take it home for thorough washing. That will remove any dirt, bugs, or chemicals present.

How To Prepare Basil For Guinea Pigs

After you’ve foraged and washed the leaves, it’s time to prepare them for your guinea pigs. The best way to do this is to chop the leaves – or the part you are offering – into smaller pieces.

This’ll make it easier for your guinea pigs to eat. It will also reduce the chances of your pig choking on them. That’s especially when offering the stems or the stalks of the plant.

How Often Can Guinea Pigs Eat Basil?

Guinea pigs should eat basil at most twice a week. And only feed a leaf or two per guinea pig. As said, too much of this herb can lead to urinary stones in the long term. As for the short-term, you can expect digestion problems.

Instead, alternate it with other healthy vegetables and fruits. That will ensure that your pet is getting a well-rounded diet.

What Flowers and Herbs Can Guinea Pigs Eat

Your guinea pig can eat basil, yarrow, clover, fennel, dill, parsley, and other herbs and flowers. Make sure they’re pesticide-free and that you offer them in moderation.

Guinea pigs are natural herbivores, which means that they eat a variety of fruits, vegetables, hay, and other plants. This includes some herbs and flowers.

Let’s take a keen look at some of the herbs and flowers;

  • Yarrow: This herb is safe for guinea pigs to eat. It packs lots of nutrients for them. Even so, much isn’t known about how much is safe. Hence, it’s best to operate at the lower end of the spectrum and offer only a tiny amount.
  • Clover: Red, green, purple, and other clover varieties are safe for guinea pigs. Your pig can eat the leaves, flowers, and stems of this herbaceous plant of the pea family. But keep the quantity at 1/4 teaspoon for average adult pigs to avoid any digestive problems.
  • Fennel: Fennel is OK for guinea pigs in moderation. This herb can offer your pig a wide range of nutrients, including vitamin C. Only keep it twice or thrice a week.
  • Parsley: Parsley is a good food for guinea pigs. It has a lot of vitamin C and other good things for them. But you should not give it to them every day because it has a lot of calcium.
  • Chamomile: Chamomile is a good herb for guinea pigs. It has a calming effect and can soothe an upset stomach. Only give your fresh herbs to guinea pigs in small amounts.
  • Rose petals and leaves: These items are safe for guinea pigs to eat. In fact, they make a good treat for your pig. Just make sure they’re free of pesticides and other harmful chemicals.
  • Rosemary: This sweet-scented option is high in Vitamin A, Vitamin C, iron, and calcium. So, it’s a healthy treat for guinea pigs. But like anything else containing calcium, don’t make it a regular treat. 
  • Sage: Sage also makes a healthy option for guinea pigs. This herb can even help with indigestion. But again, only give a small amount at a time as too much sage can lead to kidney damage.
