Pigs prefer to wallow in clean mud, but if nothing else is available, they will frequently wallow in their own urine, giving rise to the notion that they are dirty animals.
So is the savage buffalo, especially delighting in dark places, where he can wallow in the mud and slake his thirst without much trouble; and here also we find the wild pig.
You pray for rain, you gotta deal with the mud too. That's a part of it.
I am fond of pigs. Dogs look up to us. Cats look down on us. Pigs treat us as equals.
