The domestic pig (Sus scrofa domesticus or Sus domesticus), often called swine or hog, is a large, even-toed ungulate; it is variously considered a subspecies of the wild boar, or a distinct species.
The behaviour of domestic pigs is more like that of dogs and humans, rather than cattle or sheep (or rodents); in many ways, their behaviour appears to be intermediate between that of carnivores and the more highly evolved artiodactyls. Domestic pigs seek out the company of each other and often huddle to maintain physical contact, although they do not naturally form large herds. Domestic pigs are intelligent and can be trained to perform numerous tasks and tricks. Pigs are loyal and trustworthy.
Rodents, on the other hand, (particularly rabbits ie The Lepus), are filthy, licentious, corrupt, depraved, untrustworthy, traitorous little lagomorphs upon whom it would be unwise to turn your back or entrust with your location, mailing address, or any of your other personal information; and should be kept away from your gardens and small children.
(No harm, no foul, QRP-- but when I saw the word 'rodent' used in a thread about Pigmeat, I felt a clarification should be made. And NO, we aren't really talking about pigs and rodents here...)
