Are Guinea Pigs Mammals?

Are Guinea Pigs Mammals?

The answer to this question is a resounding yes! Guinea pigs, also known as cavies, are small rodents that belong to the family Caviidae. They are considered to be true mammals because they have fur or hair, give birth to live young, and feed their young with milk from their mammary glands.

Physical Characteristics of Guinea Pigs

Guinea pigs come in a variety of sizes and colors. The most common type is the short-haired guinea pig with short fur that can be brown, black or white spotted or even solid colored. Longer-haired varieties such as the Peruvian and Silkie guinea pigs require regular brushing sessions due to their long coats which may come in many different colors depending on breed.

Diet & Habitat

In nature, guinea pigs inhabit grasslands and open meadows where they typically graze for vegetation such as grasses and herbs. In captivity however, they should always have access to fresh hay and pellets specially formulated for them along with fresh vegetables like carrots or cucumbers as treats every now and then.


Cavies are social animals who thrive when living in pairs or small groups made up of their own species only – never mix different types of rodents together! They enjoy being petted but handle them gently as they can startle easily if not used to people’s touch yet (which takes time!). Additionally they make chirping sounds when excited making it very easy for owners to understand how happy these little guys really are!

Overall you can see why we love guinea pigs so much – from their cute physical characteristics all the way down into understanding more about how they act around us humans; it’s no wonder why these fascinating creatures make excellent pets!
