People who run animal sanctuaries for farmed animals often report that pigs, like humans, enjoy listening to music, playing with soccer balls, and getting massages. If given sufficient space, they will be careful not to soil the area where they sleep or eat. Pigs don’t “sweat like pigs”; they are actually unable to sweat. They like to bathe in water or mud to keep cool, and they actually prefer water to mud. One woman developed a shower for her pigs, and they learned to turn it on and off by themselves. Source: Peta2
