Are Grapes good for animals?

You might be surprised to know that grapes are toxic for many animals.

Dogs and cats cannot eat grapes, not only due to choking hazard, but also because grapes are toxic for them.

As per a the opinion of a few vets, there are some chemicals present in grapes, which are toxic to a dog’s health.

If a dog swallows some grapes, vet recommend to get it removed through vomit, else it may be fatal to dog.

Types of grapes

Grapes are found in most parts of the world.

There are almost 8000 different types of grapes.

All have equally health benefits.

Some types are considered good for wine making, some types are served as fresh fruit on table and some types are good for raisin making.

Most of us consider grapes only by colors, as specific colors have specific tastes.

Do different color grapes affect guinea pigs differently?

It’s somewhat difficult to explain which color grapes are more healthy to guinea pigs.

But according to scientific research sweet grapes are not harmful to guinea pig’s health.

They can enjoy any grape type like green, purple, or red, but in moderate amounts.

Purple is better than green grape, because it has lower content of sugar as compared to others.

Purple grapes have higher antioxidant content than green grapes.

Red grapes are better than any other type as they are enriched in antioxidants and also source of resveratrol (we will later discuss what these resveratrol are).

But don’t increase the serving amount to more than 1-2 per week.

If anything is highly nutritional it does not mean to eat it without any limit.

Overeating make them obese.

They will become lazy and less active.

Obesity is the root cause of many diseases.

To keep them fit serve them good quality food in an accurate quantity.

Benefits of grapes for guinea pigs

Little pigs will get a lot of nutrients from grapes.

You will be surprised how much this fruit is beneficial to their health.

Vitamin C

Vitamin C is an essential vitamin and antioxidant.

It improves their immune system and gives them strength to fight against common cold and other viruses.

This nutrient is important for guinea pigs because they love to live outside and more prone to viruses.

And can get ill easily.

If we discuss it in more detail than Vitamin C’s health benefits are too many.

This vitamin enhances production of a chemical in the pig’s body named serotonin, which is a happiness hormone that helps in boosting mood.

Vitamin C increases testosterone level and nitric acid too.

Which improves the body’s energy, maintains blood pressure and improves overall performance.

Vitamin C is a patent antioxidant, as mentioned earlier. It helps the body to fortify cells, if damaged, and stop the formation of cancerous tumors.

Vitamins are essential for proper functioning of the animal’s body.


Magnesium is helpful for your guinea pig to make strong bones, eventually it will protect against injury.

It is also helpful in boosting the mood of little pigs, encouraging them to learn about the environment, and giving them good sleep.

Sleep is so important in animal life.

Magnesium relaxes muscles, reduces tension, and lowers anxiety.

It is also helpful in increasing production of testosterone.


Calcium is good for bones and teeth.

Strong bones help guinea pigs run actively around.

Calcium also gives us muscle contraction.

Your pig remains happy and active for longer durations.


Iron is helpful in the creation of red blood cells.

It improves circulation of blood in the body.

And enhance energy level, Improve inhale exhale of oxygen in guinea pigs.

Potassium and phosphorus

Phosphorus and potassium are also found in grapes but only in adequate quantities.

Potassium is good for the kidney and bladder whereas phosphorus is good for teeth and bones health.


This is found in red grapes.

Resveratrol enhances efficiency of the mitochondria (energy factories for the cell).

It was not in the list but you should know that resveratrol is antioxidant, by increasing its production, it will not only work as an energy booster but also help us to increase lifespan of little creatures..

Antioxidants help us to remove toxins from the body.

They flush out harmful chemicals from the body.


Grapes are a good source of fiber.

If your guinea is constipated then this fruit helps him to pass stool.

While cleaning their cage you can get an idea how much this fruit affects their digestive system.

Serving Size of grapes for guinea pigs

1-2 medium size grapes per week is good for guinea pigs.

It should not be given daily.

And it should be considered a rare treat.

Amount of food given to pigs should strictly be monitored.

Serve the right grape.

Don’t choose unripe or rotten grapes.

Now wash it thoroughly so you can remove all pesticide spray from it.

How much food nutrition Guinea Pig needs in routine life?

All this information may seem silly !

And you may think blood pressure of guinea pig is important but an active mood may be what you want for guinea pig.

When you keep a pet, its health and happiness is important to you.

As they are wild animals.

And for wild animals, we are more concerned about whether a particular ingredient is right for them or not?

Sometimes we feed our pets similar meals as we eat.

But what if we come to know that particular food we are taking is not good for us.

Obviously we stop eating that food.

Similarly it goes for our pets.

Don’t give them over processed food.

Try to eat organic food for yourself also for your pet, as organic food is more healthy then processed food, which loses many nutrients while processing.

Processed food makes us overweight as well as ill.

Similarly guinea pigs get unwell if we feed them processed food.

It’s important for you to feed your pet with highly nutritional food that is natural and not processed.

Grapes can be given as they are not only natural but good for pig health.

This is why humans are increasingly becoming overweight, sluggish, and ill.

Can baby guinea pigs eat grapes?

Yes, small guinea pigs can eat grapes.But first give in small quantities and monitor carefully for any side effects.

If it causes any distress then stop giving grapes to small size babies.


Though serving grapes to pigs is a good idea, keep in mind the following:

  • Grapes have a high amount of sugar, and due to the small size of guinea pig this amount of sugar is not good for them
  • You should limit their sugar intake
  • Everything should be given in a small portion in moderate amounts
  • Feed them perfectly ripe fruit
  • Don’t serve them the remains of any of your meals
  • Guinea pigs food should be hay
  • Don’t give them fruit or vegetables as a main course
  • Wash their feeding bowl daily
  • Keeping a pet makes you happy, at the same time makes you responsible for your pet’s health
  • Always have a pet only if you have time to deal with them

Can pigs have grapes everyday?

A big no, if you think grape is so small in size how it may cause distress to guinea pigs than check the size of guinea pigs.

Grapes may be equal to watermelon for them.

Imagine how you feel if you eat a huge watermelon daily.

Of course you will get stomach upset, food poisoning or start to gain weight.

Serving method

Food always be served in a good manner to get more from food.

Because food looks more tempting when served in the right manner.

Guinea pigs have small sharp teeth, which help them to cut food in small parts and lower the risk of choking.

If you are still concerned then cut the grapes in two parts then serve it.

Means cut them in two halves.

If you love feeding them from your hands, cut the grapes and hold it into your palm.

Guinea pigs love to lick it and then chew it slowly.

In this way you can create a friendly bond with these creatures.

They are lovely and adorable.

Still concerned!

Ok, you can peel the grape then serve, peeling will decrease risk of choking to almost 0%.

Now you can feed without any guilt.

But in this way, you will decrease the amount of fiber that pig will get from grapes.

You can’t ignore the health benefits of fiber.

It improves blood pressure as well as is good for the digestive system.

It is also good for cleaning teeth.

You can serve them in a small food bowl, but get a sturdy bowl so it may not flip over, and create mess.

It should be tip-proof and made with good quality material.

Before serving a new meal wash or clean the bowl.

Any residue of food may build up bacteria.

Guinea pigs can eat grapes with seed or stone?

Animals are not sensible enough they can’t remove seeds, they just swallow them, it may cause choking issues.

Many animals died due to choking hazards.

Any small seed may look tiny to you but it will be big for a tiny pig, it will be a huge stone for them.

So it’s necessary for you to remove the stone or seed before serving it them, or you can choose seedless grapes that will be the better option of all.

How to know whether guinea pigs like grapes or not?

Guinea pigs are of different types just like human beings, some like to eat grapes but not all like this fruit.

Now the question is how to check their likeness.

To check their liking, offer them few pieces of grapes and see their reaction, if they only nibble at grapes and then leave it.

It’s an indication, they did not like it.

Don’t force them to eat it might cause serious discomfort.

You can serve them other fruits as well like apples, strawberry, apricot and watermelon etc.

But keep in mind before offering any food first check whether it’s good for them or not.

Before serving them any food, always keep in mind their tiny size.

Animals need food according to their body size.

Small animals only need food in small quantities.

So it’s better not to waste food.

What guinea pigs should have in their diet?

They need vitamins in abundance in their diet.

Although grapes are enriched with vitamins but unable to fulfill the required amount.

But at the same time they contribute in changing taste in diet.

We can say grapes are source of vitamin but don’t fulfill their whole requirement.

You need to add something else too for vitamin intake other than grapes.

Do they eat leaves of grapes?

There is no research evidence that helps us to conclude whether leaves will be good for them or not.

All types of grass or leaves are not necessarily good for tiny guinea pigs.

Grapes leaves are not poisonous but not good at same time so better to avoid grape vines.

Some people feed them leaves and their guinea pigs are perfectly fine.

You can check whether your pig loves it or not.

Can we serve raisins(dried grapes) to guinea pigs ?

A big no, raisins are not good for them.

Some people suggest that their guinea pigs like to eat it.

But kindly check raisins nutritional value.

It contains 59 grams sugar in a serving of 100gm.

You can say almost 60% in one serving that’s too much for a little pig.

So it’s better to avoid it.

Don’t give them any other dry fruit/ nuts.

As they are so hard to chew.

Guinea pigs may experience tooth decay.

Which will create a lot of discomfort.

Can we give vegetables to guinea pigs?

Yes we can offer vegetables to guinea pigs but not all vegetables are good for them.

You can give them lettuce, red tomatoes and pepper.

Vegetables are more healthy than fruits.

You can offer these vegetables and fruit as treats to make little pigs’ lives a little bit colorful.

Offer them vegetables more often as vegetables don’t have a high content of sugar.

Things you should avoid

Don’t feed them any type of chocolate, potatoes, nuts, mushrooms, onions, garlic, avocado etc.

These things are poisonous to your guinea pig.

So kindly avoid these foods as much as you can.

Try to keep these things away from guinea pigs.

So they do not eat them accidently.

Vet’s suggestions for guinea pig

Mostly, vets don’t recommend high sugar food (grapes, carrots) to tiny creatures as it may harm your lovely pets lifespan and also lead them to obesity, which makes life more miserable.

There are many foods available which you can use as an alternative to grapes.

Consider giving them other options which contain less sugar.

Alternative fruits for guinea pigs other than grapes

If you think that guinea pig should avoid the grapes due to high sugar content.

Then there are many other fruits that pigs can enjoy: apples, kiwi and blueberries as they have lower sugar content.

You can also serve fruits with rotation.

In this way you can give grapes in moderation and at the same moment the pig will not get bored with similar food daily.

Grapes can be a reward food.

Grapes are not refreshing for only humans but also for guinea pigs.

They love eating grapes.

Some pig owners say that once pigs get taste buds of grapes, they can do anything for grapes.

So keep grapes as a reward while guinea pigs train.

You should offer grapes only when guinea pigs listen to you.

You should offer them seedless variety.
