Guinea Pig
Cavia porcellus
🌍 Overview
Guinea pigs (cavies) have never been found in the wild - they are a fully domesticated species descended from South American wild cavies, selectively bred by Andean peoples for over 3,000 years as a food source and in religious ceremonies. Today they are one of the world's most popular small pet animals, valued for their vocal, social nature and gentle temperament. They use over 11 distinct vocalizations to communicate.

🤩 Fun Facts
🐹 Guinea Pigs Are Social
Guinea pigs are highly social and should ideally be kept in pairs or small groups. A lone guinea pig can become lonely, anxious, and even depressed.
🐹 The Vitamin C Shortage
Guinea pigs 'popcorn,' leaping straight up and twisting mid-air, when they're overjoyed. Like humans, they can't produce their own Vitamin C, so their diet needs a daily dose of fresh veggies or they risk getting scurvy!
