Why am I allergic to guinea pigs?

Guinea pigs are not always the cause of your allergy. In general, when people say they are allergic to guinea pigs then that means they are allergic to one of the allergens the guinea pig carries. Now, what actually is an allergen?

Remember when I said any warm-blooded animal which has hair, fur or feather can cause an allergy to a human being. What I actually meant was the protein that is attached to it causes the allergy. In most cases, hairs or fur is not the actual reason for your allergy; its the protein attached to it.

What exactly are these proteins? in general there are 2 types of protein attached to guinea pigs hair i.e. Cav P I and Cav P II. These proteins generally are carried and transmitted either by dander, Saliva or urine of the guinea pig. Let me explain to you all in detail how these are transmitted and causes allergic reactions in human beings.


Dander is the first and most basic cause of an allergic reaction to human beings. It is basically the dead skin cells which animals shed on a regular interval. It is one of the root allergen triggering allergies in human beings.

Most warm-blooded animals including guinea pigs regardless of their breed, size or hair length is going to produce dander which will spread in the surrounding eventually leading to allergies. These allergies are mostly the result of protein from the dander itself.


Guinea pigs saliva primarily contains Cav P I and Cav P II. These are the major Guinea pigs allergen, which causes various allergies in individuals. Guinea pigs are clean animals; they usually groom themselves all the time.

In general, Guinea pigs use a white wax-like liquid that comes from the end of their eyes and their own saliva to groom their fur. Often time this results in their saliva protein getting all over their fur.

Thus whenever we come in contact with the fur the protein allergen reacts with the individual and causes severe allergies.


Just like guinea pigs saliva the urine of guinea pigs also contains Cav P I and Cav P II. The concentration of these proteins in the urine is even higher than that of saliva.

Since guinea pigs are caged animals usually they have very limited space and when they move around, eat and pee at the same cage it is a normal phenomenon for the urine to get over their fur. Also, If their cage is not maintained on a daily basis the chances of getting infected further rises high.

This is one of the major allergens in small mammals like guinea pigs. The grease glands are the most infected area with a large number of allergens present in it.

Note: Except these many times we find that people are actually allergic to hay and bedding of guinea pigs. So, it is really important first to find the cause of the allergy and then take the necessary action to prevent the same.
