A cow is not a wild animal but a domesticated animal - we use it for leather, tallow, food, fuel, pets, all sorts of things.
A lion is a wild animal - has absolutely no use to humans outside of a trophy - you don't milk a lion. These creatures are under God's dominion
* side note, there is a huge movement away from your "cheeseburger" theory - people want their cows and pigs and chickens treated well. People are demanding quality food and ethical sourcing more and more. McDonald's is going down the tubes - nothing they do is working, people are leaving in droves and the kids don't want to eat there.
I personally raise all my own animals. Cows, pigs, chickens, lamb, turkeys, and goat - and I love them all. But I eat the bulls, the pigs, the eggs, the lamb. It's basically backyard to table. The cool thing is when we sit down for dinner and give our thanks we always mention the name of the animal we are eating. So what I'm getting at is there are lots of us who are seeking a better way to live without denying ourselves a burger.
But there is no such thing as lion burgers - apples and oranges
