Otter: in addition to the great ideas already mentioned, one can make a stormy kromer style cap with ear flaps and a thick leather brim. Very HC. Warm and pretty water resistant. Line it as an option.
Bobcat: I have seen several original pommel holsters for one’s horse pistol lined with leopard skin. You might try bobcat. You can google for pics. You might use the belly if it’s got some nice spots.
