Sloveladypowell, I understand your concern if you are allergic the something in the guinea pig's urine. However, as others have stated, your guinea pigs' health is at risk outdoors. Cold, heat, predators, insects... you get the general idea. I honestly believe it would be in your best interest to find your guinea pigs a new home where they can be kept indoors out of harm's way. I know that can be difficult, but sometimes it is necessary to sacrifice your personal happiness for the health and safety of another living creature.
