Much like cats, moose apparently put their ears back when they are irritated with you. Unlike cats, a case of cat scratch fever is not what awaits you if you further anger them. Do not anger moose. They are flailing hooves of death.
I promise to do a real post soon. I was just looking through my pictures on my iTouch and found this and giggled. It is good info for folks who might be going hiking this weekend in moose country.
