Quite remarkable and beautiful. Successful mutations get into the gene pool, and in this case it would seem that a darker coat and one that more mimics some of the large reptiles is successful for this (I assume) largely arboreal cat. Ears look smaller too. I would love to see more photos or video!

Edit: Perhaps I don't mean to say mimics reptilian patterns, but mimics large leaf patterns, which many reptilians do too.
