How do animals react to mirrors?

Animals sometimes do the strangest things when they look in the mirror.

Have you ever noticed an animal's reaction to a mirror at home, on a farm, at a zoo, or somewhere else? I'm science writer Chelsea Wald (http://chelseawald.com), and I'm collecting people's stories, photos, and videos about animals and mirrors. Tell me here! Nothing's too crazy or too dull.
