Nonhuman animals are integrated with human "monkey spheres" - e.g. people live with their pets, bond with them and give them names.

Oh yeah, absolutely. I trust my friend's judgment how much members of her monkeysphere are worth to her, and utility to my friend is weighed against utility to others in my monkeysphere proportional to how close they are to me.

My monkeysphere has long tails extending by default to all members of my species whose interests are not at odds with my own or those closer to me in the monkeysphere. Since I would be willing to use force against a human to defend myself or others at the core of my monkeysphere, it seems that I should be even more willing to use force against such a human and save the lives of several cattle in the process.

Obviously, there are people whose preferences include the welfare of cows and pigs, hence this discussion and the well-funded existence of PETA etc.

Cults are well-funded too. I don't dispute that people care about both them and animal rights. What I dispute is whether supporting either of them offers enough benefits to the supporter that I would consider it a rational choice to make.
