Guinea pig

Domesticated rodent from South America

The guinea pig (Cavia porcellus), also known as the domestic guinea pig, cavy or domestic cavy ( KAY-vee), is a species of rodent. It belongs to the genus Cavia, family Caviidae, and its closest wild relatives include the montane guinea pig. Domestic guinea pigs typically weigh between 700 and 1,200 g (1.5 and 2.6 lb) and measure between 20 and 25 cm (8 and 10 in) in length; most breeds have fur, and they have long front teeth that grow continuously, leading the animals to chew regularly to wear them down.
