Sunday I saw a guinea pig in a pet store that was not well. I informed the people working there and they said they would "take care of it". When I askedexactly how, they said they wont sell sick guinea pigs and would "take it out back". It sounded omnious. I used to breed cavies and was in a cavy 4-H club. I just couldnt walk away. So I broke my own cardinal rule and I brought the sick piggie home. He seems very listless, but is eating, drinking and pooping normally. He is not coughing, or sneezing and an overall exam shows that there is nothing obviously wrong with him (I checked teeth etc). However, he has an eye problem that I suspect is making him very uncomfortable. One eye is very runny and keeps getting stuck shut. The lower inside of the lid is red and swollen. I couldn't see any debris in there and I flushed the eye with sterile saline. (The other eye is bright and clear). Then he got a prescription of Neomycin, Polymyxin B Sulphates and Dexamethasone Opthalmis Suspension (1 drop, three times a day). I started this last night. I have also been using a moist cloth a few times a day to clear around the eye. The eye is less red today, but otherwise unimproved. I have added vitamins to his water, am feeding him snacks of kale, parsley and carrots, keeping him warm and quiet. Does anyone have any thoughts on this? I think his eye is just making him miserable. Please help. please please.....
