Well to answer your question YES you can be allergic. You might be allergic to the guinea pig itself or if you are like me you are allergic to something little like their hay. To try to help with you allergies with them try brushing them every day. Most people are just allergic to their hair so I also suggest that when you are holding them that you put a towel or a blanket under them (I also do this because mine have a tiny bladder). The last way that I can think of is that you vacuum around where your guinea pigs stay so there is not to much spreading around the house.
