Your guinea pig more than likely had an
upper respiratory infection, and at the stage of discharge around the eyes, they usually will not respond to medication. Sterilize the cage if you are going to keep your other pig in it with a 10% bleach solution, rinse well, air dry, and rinse again. Discard all bedding, food, shelters and toys (if wooden or chewed on). Keep your other pig warm at all times. Weigh him everyday to make sure he is keeping his body weight. If not take him to a vet that specializes in exotics- a dog and cat vet will not know what they are doing. If your other pig is sneezing, coughing, has a runny nose, or feels like he isn't as warm as he should be, take him to the vet immediately. These are some of the early stages of a URI. Give your other pig vitamin drops everyday, and provide fresh greens and carrots. Do not leave fresh food in the cage for more than 4 hours. Switch your bedding to an all natural paper bedding- pine,aspen, cedar, etc can lead to the development of URIs. The bedding is called CareFresh, and it can be found at most
pet stores and at PetsMart.
