Have you spent any time watching nature? Predation? Animals fundamentally consider each other such. Cougars consider horses food and horses "prosecute" cougars if they come close enough by kicking them to death. Killing threats is what any animal capable of doing does.
Animals are fundamentally incapable of grasping the concepts of rights and would not respect them. Applying human standards to them is fundamentally anthropomorphic chauvinism and absurd hubris.
Under human standards we should start hunting or capturing more male lions because they would happily commit infanticide to make lionesses reproductively available. Naked mole rats are incestuous pedophiles. It is important to remember that nature does not care about you and cannot care about you.
