Porc de guineea

The guinea pig (Cavia porcellus) is an animal that was used until the 20th century as an examination or laboratory test animal. It belongs to the family Caviidae and is probably related to 'Cavia tschudii'. In Europe and Asia the guinea pig is commonly kept as a pet, with the name guinea pig. It originated in South America, where it was domesticated between 5000-2000 BC. In Europe it was imported as a pet by the 16th century, and from Europe it was taken by humans to North America. The South American guinea pig is larger than European and North American guinea pigs and is consumed by humans. By the 20th century it was also consumed in Europe.

Guinea pigs are not very agile, but they can jump over small objects. They are not very good climbers. When guinea pigs are excited they will start to jump (in English: popcorning). They are also very good swimmers.

A guinea pig's eyesight is not as good as a human's, but it can see objects that are relatively close very well. The sounds they make are their way of communicating.

Guinea pigs can learn complex paths to food, and can accurately remember a learned path for months. Their strongest problem-solving strategy is motion.
