Today's new jigsaw puzzle features three cute Guinea Pigs eating. The scientific name of the common species is Cavia porcellus, with porcellus being Latin for "little pig". How the animals came to be called "pigs" is not clear. They are built somewhat like pigs, with large heads relative to their bodies, stout necks, and rounded rumps with no tail of any consequence; some of the sounds they emit are very similar to those made by pigs, and they also spend a large amount of time eating.They can survive for long periods in small quarters, like a 'pig pen'. There are two different types of guinea pig coats and they are self patterns and marked patterns. Self patterns are made up of just one color which could be white, cream, buff, gold, black, slate, lilac, chocolate, beige or reddish brown. The marked patterns are made up of two or more colors.
