Hello! I'm new here, and I'm really worried about my hedgehog. He's three years old and has always been very antisocial, never liked to be held and is the happiest when left alone in his house. A couple of weeks ago, during his bath time, I noticed that his left eye is considerably lighter than the right one, which is a dark black. It almost looks like a glass eye! It's even more noticeable when you look at it under the light, then it's obvious it's not the normal color. It doesn't protude at all and I haven't seen him scratch it or act any different, but I'm really worried he might be in pain. Do any of you know what might be wrong with it? I've been trying to find something online but nobody seems to know what it is. I would really appreciate the help, please!
