An introduction to Guinea Pigs

The guinea pig (or domestic guinea pig) is a member  of the rodent family, specifically the Cavildae family (Cavia genus). They are also knows as cavy or domestic cavy. They actually originate from the Andes in South America despite their common name suggesting they are from Guinea in Africa.

Spanish sailors travelling from South America in the 16th century brought guinea pigs to Europe and they were really expensive to purchase. This meant that only the wealthy could afford them. Thankfully guinea pigs are much more affordable now and can be purchased from a wide range of pet stores across the UK, Europe and the US.

Guinea pigs have been rising in popularity over the last decade thanks to their friendly and gentle nature making them the perfect pet for all ages. In some parts of the world there are organisations dedicated to the specialised breeding of specific breeds with varying coat colours and textures.

They take shelter in the abandoned nests and burrows of other animals although do not actively make these homes themselves.

Social

Guinea pigs are social creatures and it is recommended that you purchase more than one guinea pig when buying. Previously it was believed that guinea pigs and rabbits cohabited well together however now this opinion has become divided with research suggesting rabbits tend to bully the smaller guinea pigs. Evidence shows that some larger animals (such as dogs and cats) can be trained to tolerate guinea pigs with some showing genuine affection towards them.
