Pigs

It is more trouble physically to move a semi-wild pig against it's will than to kidnap a man.

Pigs are harder to get hold of than men and big ones are stronger than a man and they cannot be intimidated with a gun.

There are also the tusks to consider if you want to maintain the integrity of your abdomen and legs.

Tusked pigs instinctively disembowel when fighting the upright species, men and bears. They do not naturally hamstring, but can quickly learn the behaviour.

If you need to maintain the animal alive, you cannot haze it with electrical shock, as pigs are prone to fatal coronary fibrillation.
