Summerfly I wasn't talking specifically about foz hunting - and foxes, dogs and other animals getting into a field of sheep will often embark on a frenzy of killing, far more than they can ever consume, rather as if they just enjoy the act of killing.
Yes they do enjoy it - it is because they are programmed to do so, because without it they would simply not survive.
We know that many predatory animals apparently kill for pleasure. Cats of all sizes, dolphins, canines, bears and others and of course humans.
However, we are blessed (cursed) with a cognitive brain that allows adaptability which is simply not available to other species. We have therefore developed myriad cultures. Killing other sentient beings for pleasure is one that in many cultures is now thought no longer acceptable
