Pigs

Pigs, Swines, Hogs . . . Whatever you call them they are thought of as either cute and pink (Wilbur, Babe) or ugly and dirty. Why do pigs get such a bad rep as being dirty animals though? Pigs actually like to be clean. If they are given enough room they will make sure to keep their sleeping and eating spaces clean. Sure they like to roll around in mud, but don't you get muddy sometimes? Plus their mud rolling has a very practical purpose. Pigs can't sweat (there goes the "sweating like a pig" thing) and roll around in the mud to keep cool. Think of it like a day at the spa. Pigs are also quite smart. Young pigs learn their names very quickly and will even learn tricks like a dog, but much faster. One fun fact about pigs is that mother pigs will grunt (or sing) to her piglets while nursing.
