Fallacy
Because wolves and other predators eat animals, and because humans are also animals, it's okay for humans to eat animals.
Response
Non-human animals do many things we find unethical; they steal, rape, eat their children and engage in other activities that do not and should not provide a logical foundation for our behavior. This means it is illogical to claim that we should eat the same diet certain non-human animals do. So it is probably not useful to consider the behavior of stoats, alligators and other predators when making decisions about our own behavior.
The argument for modeling human behavior on non-human behavior is unclear to begin with, but if we're going to make it, why shouldn't we choose to follow the example of the hippopotamus, ox or giraffe rather than the shark, cheetah or bear? Why not compare ourselves to crows and eat raw carrion by the side of the road? Why not compare ourselves to dung beetles and eat little balls of dried feces? Because it turns out humans really are a special case in the animal kingdom, that's why. So are vultures, goats, elephants and crickets. Each is an individual species with individual needs and capacities for choice. Of course, humans are capable of higher reasoning, but this should only make us more sensitive to the morality of our behavior toward non-human animals. And while we are capable of killing and eating them, it isn't necessary for our survival. We aren't lions, and we know that we cannot justify taking the life of a sentient being for no better reason than our personal dietary preferences.
