I noticed yesterday that Lily's eye was cloudy blue color. I looked up what it could be and the consensus seemed to be a scratch on the cornea. I called the vet and got an appt. Luckily it was just a scratch. We are now home with eye drops to administer 3 times a day. I was so worried she might be going blind, I'm so glad that wasn't the case. I love my piggies to pieces.
