How different would have brained animals evolved if there were mirrors everywhere in nature?

Many pets are very disturbed by the presence of mirrors or other reflecting surfaces where they see their own image. If there were many reflecting surfaces in nature I would think that it would represent a fitness cost to the individual that is constantly scared of its own reflection. So that made me wonder...
How different would have brained animals evolved if there were way more (and better) reflecting surfaces in nature?
