People are attracted to guinea pigs because of their quiet sweet dispositions, their small size, and because they very rarely bite!
Guinea pigs, also known as cavies (cavy), are a very popular pet for children and adults alike. They are relatively inexpensive to keep and easy to house and feed. They tend to be hardy little animals that don't easily contract diseases. If well taken care of, a guinea pig life span can run between 8 - 10 years.
Classed as rodents, they originated in South America and are the descendents of the Tschudi Guinea Pig (Montane Guinea Pig) Cavia tschudii.
