In my experience I need to kill 1 large cow every 2 years to personally survive. That's good, because that's about my personal limit for how long I'm happy to have a cow in my freezer without charging it rent.

I need to kill an absolutely obscene number of avocados, tomatoes and other fruits and vegetable too otherwise that cow will not last me 2 years. Those are the screams that truly bother me. The daily cries of my vegetables going to slaughter.
