So this is how i'm going to rationalize the Grimm team creating two Jaguar Wesen: The Balam is a Black Jaguar (also known as a Black Panther) Whereas the Yaguarate is the regular golden-furred variant. As a side note, the golden furred cat that Nick guessed was a Balam in The Icy Touch may have actually been a Yaguarate. Feel free to post your thoughts on this.
