Those who defend pig factory farms argue that the farrowing crate is necessary because sows can sometimes accidentally crush their piglets. In the same way that the risk of a forest fire can be reduced by preemptively clearing the forest of all its trees, there is a cockeyed logic to this claim. The farrowing crate, like the gestation crate, confines the mother in a space so small she cannot turn around. Sometimes she will also be strapped to the floor.
