I'm doing this for a friend so I can't say much as far as the chameleons care unfortunately. The chameleons name is Rin, again, I don't know much. But the last time I saw him, I noticed this strange bump on his eye and when I pointed it out, my friend said that it has been there for a while. It worries me and I don't know much about chameleons as I don't own one myself. What can I tell my friend to do for him? She doesn't have internet so that's why I'm doing this. I doubt that she has the money to take him to the vet :/ what I do know: he is in a mesh/wire cage? I think that's what it's called. He has a water bowl and eats a mix of cricket and mealworms. Only one eye is like this.
