I got a new baby guinea pig three days ago. He is about eight weeks. Last night, I noticed both his eyes were really crusty. I showed my roommate and told him that it said online to wipe the eyes. My roommate told me not to. It looked like it was healing that way and if I gently cleaned it, I would forcibly rip them open. I thought that was silly, but I listened to him because I didn't want to freak him out. Well, this morning one of the eyes got a lot worse and it was completely swollen shut with the crust. I had a guinea pig with a similar issue before. They told me it was only pink eye and gave her eyedrips at the vet, but this worries me more just because he is so young and I don't know how stong his immune system is. I have no idea what went wrong because I only just got him. I will edit my post to include a picture soon.
