Can Airborne (the super-vitamin tablet that dissolves in water) kill guinea pigs? My daughter has been giving a few drops of this to her guinea pig each day for about two days, because the guinea pig was sneezing and making a deep snorting sound. The guinea pig has shown improvements with her breathing, but someone told us a medication like Airborne could cause an animal's stomach to explode. Is this true? If so, are there any other natural vitamin remedies that would help build up the guinea pig's immune system?
