I have a lavender guinea that appears to have something in it's eye. It wasn't apparent until we were applying ointment to it's eye. We had noticed that he was keeping his eye shut most of the time and like I said when we were applying some eye ointment to it we noticed that it looks like there's something in it. Not physically poking the eye from what we can see but under the lid. A quick attempt at removing it was useless. Any suggestions?
