Like what Old Rabbit said, I'm a hunter and if we get an deer we mostly eat all of it, and I ask for the antlers as a keep sake for that one trip to remember it as a fun time and that we actually got a deer. So same with a tail if you went Fox hunting(usually Fox hunting is for mostly hunting clubs) and you actually got a Fox you could keep that to remind you had fun and you actually got your target (and a tasty meal).
