I agree with you but think you miss that the common concern is with the farming process. The fact to eat another animal usually comes as

- a shortcut : “I don’t eat animals” instead of “I avoid encouraging the farming process by consuming the product of those farms: […]”

- and/or a following philosophic stance, that seems logical (debatable) when someone avoid encouraging the farming process.

Few are the vegans that claims that an animal eating another animal is not natural, or that they cats wouldn’t eat them in the condition you describe (which to be honest, rarely happens).

There are plenty of great moral arguments for why animals (or humans) shouldn't be eaten unless they died of purely natural causes. Factory farming is just the strongest to argue against and the main source of both suffering and death, so it's what people focus on. If factory farming were abolished overnight, vegans and vegetarians would (rightly) immediately move onto hunting and small farms.

(I personally think there's nothing wrong with home/farm egg laying as long as the animals are taken care of well and the male ones aren't killed. That's why I'm vegetarian rather than vegan.)
