What's a Zoo Cougar? It's a maniacal big cat screeching at the top of its lungs and trying to escape a cage. Oh, and its also a really cool streamer pattern. White is one of the top producing streamer colors and the famous Zoo Cougar in this fishy color does not disappoint. The Zoo Cougar has enticed large fish in a variety of waters around the world. Fish it and see for yourself: The combination of the white head, a natural speckled flank wing, a flashy pearl body and several other attractive materials gives this fly a profile and swimming action that is hard for any fish to refuse.
