Humans weren't originally omnivores in the garden of Eden and the Bible says in the end the wolf will live with the lamb so you better get used to not eating animals in eternity. It's only this relatively short period of time on Earth that you will be eating them. There are no slaughterhouses in heaven. It was only after the fall of man that humans were given permission to eat animals, and permission isn't the same as an ideal. I can give my kids permission to eat yummy food but that doesn't mean I'm recommending it as the ideal. I'm talking in terms of moral ideals here — I'm well aware the omnivore diet is the biological ideal in terms of bioavailability of nutrients due to probably evolutionary reasons to do with what our ancestors ate. But this doesn't entail it's the moral ideal.

I have no problem with you eating carnivores as they're going to inevitably kill a whole bunch of peaceful nonaggressive herbivores so the rule of self defence applies, it would be a righteous preemptive killing in self defence. Carnivorous cats and dogs shouldn't be exempt from this on the basis "they're our friends so they get special status" cause the vast majority of people are NOT pet owners and are NOT their friends, otherwise a minority could befriend cows and then we couldn't eat cows anymore, plus the whole thing is an appeal to population fallacy anyway. When I try to help stray cats I feed them artificial kibble which contains synthetic supplements. These haven't been proven broadly but it's better than killing them, I would rather be a bit malnourished than dead. You hate me cause I think animal lives matter, stop being so demonic please. Like I said you wouldn't get angry if an animal defended their own life so why care if I defend them. Just calm down bro.
