I noticed yesterday that my eleven week old piggy Charlie had some crust around his eye and wouldn't stop squinting it. I wiped the crust off with a damp cloth but the problem was still there today. I read online that you can use some polysporin antibiotic eye drops to help clear it up. I bought some tonight but now I'm just wondering how much of it I should use. I figure about one drop but I don't want to over do it.
