Also whoever said we only eat animals that can't fight back is an idiot.
We still hunt down and eat animals like bears, sharks, wolves, snakes, scorpions, warthogs, ect.
However it's pretty easy to bred animals into food. Let's say bears for example, demoralize them when they are young. De-claw them, de-fang them and beat them to death for months until ready for slaughter. This stuff can be done to any animal.
