Is the mascot for the University of Colorado a real buffalo?

Indeed, Ralphie is a real buffalo. She is the fifth live Buffalo mascot for the University of Colorado in Boulder, CO. She lives in an undisclosed location and makes an appearance at every home football game, running a horseshoe shape from one side of the endzone around the perimeter of the field into a trailer on the other side of the same endzone. She is managed by a team of student handlers who go through a rigorous tryout program to join her team.
