Guinea pigs are born with their eyes open (the guinea pig in the picture is only 8 hours old), which is uncommon for most offspring in the animal kingdom. They are also born with a great deal of fur (see picture (!)), which is also abnormal since most animals are bald at birth. It just keeps getting weirder, with the guinea pig being capable of eating solid food from day one. They don't skip milk altogether, but are well able to eat solid food on the very same day they are born.
Despite having such large, orb-like eyes, guinea pigs suffer from rather poor eyesight. Their hearing is very sensitive to make up for the lack of sight. Guinea pigs are really good at swimming despite their sausage shaped bodies. They like to hop, and do so quite frequently when they are happy, but they don't rise very far off the ground. Guinea pigs are unable to climb.
The guinea pig has a rich history of serving as a food source. The first known instance of guinea pig cultivation occurred in 5000 BC in what would be modernly known as Bolivia,
Guinea pigs are believed to be descended from various closely related species of cavy found living wild in South America. These wild cavies have a social structure similar to cattle, with the cavies living together in herds.
The ideal guinea pig diet is primarily grass, and like humans guinea pigs must get their vitamin C from their food.
