The guinea pig, also known as cavy, is a domesticated rodent native to the Andes, widely kept as a pet in Brazil and around the world.

About this subject

The guinea pig (Cavia porcellus) is a herbivorous rodent domesticated thousands of years ago in the Andean regions of South America. Unlike its wild relatives, the guinea pig no longer exists in the wild and is entirely dependent on humans for survival. In traditional Andean culture, especially in Peru, Bolivia and Ecuador, these animals are raised not only as pets but also as a food source, with cuy being a typical dish at festivals. In Brazil, they have become popular as gentle and social pets, ideal for apartments, and are often adopted by families with children.

These rodents have a lifespan of up to 8 years with proper care. They feed mainly on hay, vegetables and specific pellets, and require supplemental vitamin C because they cannot produce it naturally. They are gregarious animals, best kept in pairs or groups, and communicate through a variety of sounds such as the classic 'wheek' of excitement, purrs and squeaks. Reproduction is quick: females can have litters of 1 to 6 pups after a gestation of about 68 days.

In science, the term 'guinea pig' has become synonymous with experimental subject, as these animals were widely used in laboratory research, especially in vaccine development and nutrition studies. However, ethical guidelines now restrict their use and promote alternatives. In Brazilian pet fairs and specialty stores, it is common to find several breeds such as Abyssinian, Peruvian and Teddy, which differ by coat type and colors. Responsible ownership requires adequate space, environmental enrichment and frequent veterinary care to prevent dental issues and obesity.
