My experience has suggested that just about any live animal will resist being plucked of feathers or fur for fly tying purposes. Smaller animals will often demonstrate an amazing foot speed and broken field running ability. Larger animals may flee if you're lucky but more than likely will stand their ground and demonstrate their ability to use claws, beaks, wings and/or teeth. Above all do not try to dry shave a badger, a wolverine or a bear cub (even a small patch). 8T
