Many people consider getting a pet, but they are unsure if they will be allergic to the animal or if they will not. Before getting a pet, it’s a good idea to educate yourself on everything there is to know about the animal. When I was debating whether or not to get a Guinea pig a few years ago, the first thing that came to mind was whether or not I would be allergic to it. Is it true that guinea pigs are hypoallergenic? In order to better understand guinea pig allergy, I conducted some research. Here’s what I discovered!Guinea pigs do not have hypoallergenic properties. To be more specific, any warm-blooded animal with a coat of hair, fur, or feathers has the potential to cause an allergic reaction in humans. However, despite claims from many websites and individuals that there are special little breeds that are hypoallergenic, studies have found that even breeds with no fur or hair can cause an allergic reaction in some people.But what does the term “hypoallergenic” actually mean?

The term “hypoallergenic” refers to something that is either free of allergens or has a very low chance of causing an allergic reaction in humans when exposed to it. There are no government-mandated standards for what constitutes hypoallergenic food or clothing.

Because of this, there is no standard procedure that we can follow in order to determine whether something is hypoallergenic or not. That is why many people assert that a product is hypoallergenic or that a particular breed of pet is hypoallergenic, when this is simply not true in practice.

Does that mean you should be concerned about the allergic reaction?

No, guinea pig allergies should not be a major source of concern unless and until you are a highly sensitive individual like me. As you can see, any pet can cause an allergic reaction in any person, but that does not rule out owning a pet altogether.

Many people, including those who are allergic to pets, enjoy having pets in their homes. However, many people believe that once they are diagnosed with an allergy to a pet, they are unable to have any pets. Today, we’re going to dispel this urban legend.

Are guinea pig allergies common?

No, Guinea pigs are not the type of pet that typically causes allergies in a large number of people. Although most animals, including mice, cockroaches, guinea pigs, cats, dogs, and even horses, can cause allergic reactions in humans, there are some exceptions.

Horses and cats, out of all the animals listed above, are the ones that cause the most allergic reactions because they carry the most allergens. People who are allergic to cats are twice as likely as those who are allergic to dogs or any other animals when it comes to small animals.

Given that cats roam around the house, spreading the allergen all over the place, and that dogs are the ones who are closest to us, we should avoid cats. They pose a greater threat than a small animal such as a guinea pig that is present in its cage in a specific area of your home.

Can you be allergic to guinea pigs?

Yes, it is possible to develop an allergic reaction to guinea pigs. It has been observed that people who are sensitive or who have a family history of asthma, hypersensitivity, or other allergies to guinea pigs can develop an allergy to them. 90% of the population, on the other hand, does not share this view.

Many people believe that guinea pigs are the source of their allergy, but this may not always be the case, depending on the situation. It’s possible that when you brought them home, they had something attached to their skin or fur that was causing the allergic reaction to occur. It is preferable if you first consult with a doctor to determine what is causing the reaction before making a final decision.

Some people are also allergic to the smell of guinea pigs, which is understandable. In this article, you will learn everything you need to know about the smell of Guinea pigs and how to avoid it.

Why am I allergic to guinea pigs?

Guinea pigs are not always the source of an allergic reaction. Most of the time, when people claim to be allergic to guinea pigs, it is because they are allergic to one of the allergens carried by the animal. So, what exactly is an allergen, and how does it manifest itself?

Remember when I said that any warm-blooded animal with hair, fur, or feathers can cause an allergic reaction in a human being? Well, that is still true. To be precise, I meant that the protein that is attached to it is responsible for the allergy. In most cases, it is not the hairs or fur themselves that are the source of your allergy; rather, it is the protein that is attached to them.

What are these proteins in their most basic form? Cav P I and Cav P II are the two types of protein that are commonly found attached to the hair of guinea pigs. These proteins are generally carried and transmitted by the guinea pig’s dander, saliva, or urine, depending on the species. Allow me to explain in detail to you all how these are transmitted and how they cause allergic reactions in human beings to occur.


Humans are allergic to dander, which is the first and most fundamental cause of an allergic reaction. It consists primarily of the dead skin cells that animals shed on a regular basis from their bodies. It is one of the primary allergens responsible for the development of allergic reactions in humans.

It is inevitable that the dander produced by warm-blooded animals such as rabbits and guinea pigs, regardless of breed, size, or hair length, will spread throughout the surrounding area, eventually causing allergic reactions. Generally speaking, these allergies are caused by proteins found in the dander itself.


Cav P I and Cav P II are the most prevalent cavitation proteins in guinea pig saliva. The most common allergen in Guinea pigs, which causes a wide range of allergic reactions in humans, is this one. Guinea pigs are clean animals, and they groom themselves on a regular basis, if not constantly.

Guinea pigs groom their fur with the help of a white wax-like liquid that comes from the end of their eyes and their own saliva in the majority of cases. Their saliva protein is frequently deposited on the surface of their fur.

In this way, whenever we come into contact with fur, the protein allergen reacts with the individual, resulting in life-threatening allergic reactions.

Cav P I and Cav P II are found in the urine of guinea pigs, just as they are in the saliva of the animals. It has been discovered that the concentration of these proteins in urine is even higher than that in saliva.

Given that guinea pigs are caged animals, they typically have very limited space to move around in. Additionally, because they eat and pee in the same cage, it is not uncommon for urine to seep through their fur. Furthermore, if their cage is not cleaned on a daily basis, the likelihood of them becoming infected increases even further.

Small mammals, such as guinea pigs, are particularly sensitive to this allergen, which is one of the most common in the world. The grease glands are the most infected part of the body because they contain a high concentration of allergens.

Note: Aside from these instances, we have discovered that many people are actually allergic to guinea pig hay and bedding. As a result, it is extremely important to first identify the source of the allergy and then take the necessary steps to prevent it from recurring.

Are skinny pigs hypoallergenic?

No, just like regular guinea pigs, skinny guinea pigs can cause allergies in people.

Hair is not the source of allergy, but it is unquestionably a carrier of allergen in some instances.

As a result, the idea that a hairless guinea pig is hypoallergenic is a complete myth.
