The guinea pig (Cavia porcellus) is a domesticated rodent native to the Andes region, known as a popular pet and as a traditional dish in countries like Peru and Ecuador.

About this subject

The guinea pig, also known as cavy or cuy, is a rodent species originating from the Andean region of South America. Domestication began over 5,000 years ago, when indigenous peoples like the Incas raised them for food and rituals. Today, they are among the most common pets in Western households, valued for their docile temperament and ease of care.

Culturally, guinea pigs hold great significance in countries such as Peru, Bolivia, Ecuador, and Colombia, where they are served as a traditional dish during festivities, either roasted or fried, known as "cuy chactado" or "cuy al horno". The meat is high in protein and low in fat, making it nutritionally valued. In some Andean communities, the animal is also used in traditional medicine, e.g., by rubbing a guinea pig against a patient's body for diagnostic purposes.

Guinea pigs have distinct traits: they are herbivores, require dietary vitamin C supplementation (like humans), and communicate through various sounds such as squeaks and purrs. Unlike rats and mice, they have no visible tail. Their captive lifespan ranges from 4 to 8 years. Their use as laboratory animals gave rise to the term "guinea pig" for experimental subjects, though such use has significantly declined.
