Guinea pigs are popular pets, especially for families, largely due to their wonderful temperaments. They are social, keep a daytime schedule, and rarely bite, even when they are stressed. Guinea pigs do need a large cage and opportunities to exercise and play outside of the cage, as well as a diet that provides adequate vitamin C and roughage.

Introduction to Guinea Pigs

Guinea pigs live, on average, 6 to 8 years, weigh about two to three pounds, come in a variety of colors, are very social, and make great pets for children and adults alike. Learn some facts about guinea pigs and what you need to consider before choosing a guinea pig as a pet.

Guinea Pig Breeds

Did you know there is a hairless variety of guinea pig? There are actually about a dozen different breeds of guinea pigs like texels, coronets, Baldwins, and more, all of which can be categorized by their hair (or lack thereof).

Guinea pigs need a lot more room to run around than most people provide them with. Large cages can be purchased online or in a pet store, or a custom enclosure can be created using small fencing or pens to give your cavy plenty of space to run around safely. But even if you have a large cage, do not forget that your guinea pig will love some time to roam about freely.

Bedding for Guinea Pigs

Guinea pigs use the bathroom wherever they please so you will need bedding that is absorbent but does not harm your pet. Wood shavings used to be popular, but more information on how they can harm pets has been discovered over the years, especially cedar shavings. Popular choices include fleece, which can be purchased from a craft store and then washed and reused when it gets dirty, and various kinds of paper-based small animal bedding.


Vitamin C is the key ingredient in a guinea pig diet. Like humans and capybaras, guinea pigs cannot make their own supply of vitamin C to meet their daily needs, so it must be supplied for them. Guinea pig-safe vitamin C supplements and special guinea pig pellet food are fortified to help meet this nutritional requirement. Also, guinea pigs need a large amount of roughage, such as timothy hay. Stay away from sugary treats and seeds because they can cause gastrointestinal issues.

Should you bathe your guinea pig? How do you trim guinea pig nails? It's important to learn how to groom your guinea pig and what shampoo you can safely use on your cavy. Don't worry, you don't need to brush your guinea pig's teeth—but you do need to pay close attention to them. Guinea pigs' teeth grow continuously throughout their lives and can become overgrown due to a variety of reasons. Overgrown teeth can cause your guinea pig a lot of pain and they may stop eating. Their teeth can be trimmed or removed, but hopefully, your guinea pig will never need either procedure.
