Hello everyone. Recently I have noticed that my green iguana has a hard lump on his left side. I am concerned. He is acting quite normal and eats like a champ. I have a dripper installed and a water dish for him to lay in as well as a fogger. So I believe he is well fed and hydrated. His behavior is normal doesn't mind being held. He even let's you touch the lump without a reaction. Does anyone have any experience with something like this?
