Share it with Your Friends!

Often, we see hamsters in some videos having fun eating sunflower seeds. We are aware that guinea pigs and hamsters are both rodents. With that being said, can guinea pigs eat sunflower seeds, too?

The quick answer is no and it is not recommended.

Though sunflower seeds contain many nutrients, the amount of fat, carbohydrate, and fiber does not match the proper diet of the guinea pigs. Therefore, it is better not to give them at all.

Now, you understand that you shouldn’t feed guinea pigs sunflower seeds. But, what if you accidentally give it to them? What would happen to your guinea pigs?

This article contains a lot of interesting facts that you should know about. So, we better get started now.

What Happens When Guinea Pigs Eat Sunflower Seeds?

There are two things that may possibly happen when guinea pigs eat sunflower seeds: choking and fattening

Let’s dig deeper into this question and find out how sunflower seeds can be harmful to the cavies.


Eating sunflower seeds can cause major choking danger among guinea pigs. If you give these seeds to guinea pigs, they will definitely enjoy eating them.

However, you should remember that sunflower seeds are hard to swallow especially for tiny pets like cavies.

The shells of sunflower seeds are dangerous, too. But, this is not the major problem because guinea pigs will not eat the shell.

The main cause of choking danger is the seed inside the shell as it is so hard and it can clog the throat of your tiny pet.

Surely, you don’t want to see them struggling to breathe just because of sunflower seeds, right? Therefore, keep in mind not to give these seeds to your guinea pigs.


Sunflower seeds are very rich in fats and they can cause fattening among cavies. It is good to know that guinea pigs require a strict low-fat diet, which is the complete opposite of sunflower seeds. Well, give them some veggies instead!

According to the University of Illinois’ College of Veterinary Medicine, sunflower seeds do not fit in the low-carbohydrate, low-fat, and high-fiber diet of the guinea pigs.

Needless to say, an unhealthy lifestyle of a guinea pig will cause its early death.

Take Note:

Most commercial foods for pets are meant to attract the pet owners (since they are the customers) and not the pets.

A good example is the sunflower seeds for guinea pigs. These seeds are dangerous for the cavies and better not be given at all.

However, the eye-catchy packaging of the commercial food and its neat and decent-looking food inside attracts the pet owners the most. Thus, these factors will trigger them to buy believing it’s the best for their pets.

Well, as pet owners we should be responsible enough to know what to feed our pets.

As people usually say, “Good pet owners treat their pets not as animals but as family members.” Surely, we don’t want to put our family members in danger, right?

Can Guinea Pigs Eat Sunflower Stalks?

Yes, they can eat sunflower stalks. The stalks of sunflowers are crunchy like celery that guinea pigs can eat too.

Moreover, these stalks have low-fat, low-carbohydrates, and high-fiber content that can pass the required diet of the guinea pigs.

However, these are not the usual safe food for guinea pigs and there are many other better options. So, if you want to feed this food to your guinea pig, better give it once every two weeks or once a month (just like a treat).

On the other hand, rabbits are fed with these stalks but not often.

This only shows that food should always be given in moderation.

Can Guinea Pigs Eat Sunflower Leaves?

Yes, they can eat sunflower leaves. Just like the sunflower stalks, the leaves and all the green parts of the sunflower contain low-fat, low-carbohydrate, and high-fiber.

Therefore, these parts are fine to feed to your guinea pigs.

Nonetheless, it is better to give these foods as treats (only given once or twice). It makes us better pet owners if we know what to feed our cavy. Healthy guinea pigs will live happier and longer.
