The situation is even odder when we consider that most cows - and other farmed animals - are typically treated far worse than most horses. Though their suffering is kept hidden away behind the closed doors of factory farms, animals raised for food are routinely treated as meat-, milk-, and egg-producing machines. The overwhelming majority of chickens, pigs, and turkeys, for example, spend nearly their entire lives crammed inside massive warehouses. Hundreds of millions of them are locked away inside tiny cages or crates, barely able to move.
