Spoiler: milk cows get murdered as well. A milk cow is productive for about 5 years, after which they usually get slaughtered for pet food. In that time, they need to have about 3 calves, to continue producing “good returns” amount of milk daily. Two of those calves are not needed to replace the cow, so they get - guess what? - slaughtered and processed to pet food. Stupid me grew up next to a milk farm and didn’t realize that until way later than I care to admit. Also, I still eat cheese (reduced amounts) and that’s a moral dilemma for me.
