Things to Know When Owning an American Guinea Pig

Let’s make sure you know all of the important stuff about your American guinea pig.

Food & Diet Requirements 🥕

American guinea pigs require the same basic diet that all guinea pigs need. You want to make sure there is a steady supply of clean high-quality timothy hay for them to eat. This food wears down their teeth and is high in fiber, which promotes a healthy digestive system.

According to the Small Animal Vet Hospital, your guinea pig should eat about 20% of their body weight in vegetables per day. Many people recommend one cup. The majority of vegetables should be green with a smaller portion of colored vegetables to add vitamin C to the diet. These vegetables need to be fresh because vitamin C diminishes quickly.

Your American guinea pig will also require between 1/8 and 1/4 cup of food pellets fortified with vitamin C each day. You can purchase these pellets in a pet store, and we recommend choosing the highest quality brand you can afford.

Tiny portions of fruit are also acceptable to give your pet on occasion, but these fruits should be fresh and high in vitamin C.

Exercise 🐹

According to the RSPCA, your guinea pig can remain active for up to 20 hours a day, which means your pet needs ample room to move around and exercise. Experts recommend getting the largest cage possible. Make sure the cage provides a flat open area as opposed to a multi-level environment because guinea pigs don’t like to climb like ferrets do.

Training 🎾

American guinea pigs are bright animals that love to play, especially when you get involved. They are smart enough to learn quite a few tricks and can understand just about any command if you have a lot of patience and tasty treats. Once your guinea pig is a few weeks old you can try out of few of the following tricks.

Litter Box

Training your American guinea pig to use the litter box is likely going to be your favorite trick because it means less work for you later.

  • To train your guinea pig to use a litter box, place a litter box into the cage where they usually relieve themselves.
  • Place timothy hay and fecal pellets in the litter box.
  • When your pet uses its litter box, make some noise, and give it a treat.

Once you train your guinea pig to use the litter box, it will continue to use it for its lifetime.

Stand Up

Training your American guinea pig to stand up is just as easy as training it to use a litter box.

  • Hold a treat above their head while repeating the word “Stand.”
  • After some time, your pet will stand to get the treat, and it will have heard the word several times.
  • Do this twice a day, and in a few days, your guinea pig will stand on the first command without dangling the treat.

Obey Commands

You can train your guinea pig to follow any command by following the system above. The trick is to pick something simple that you can coax them into doing. Pair that goal with a word, a treat, and repetition, and you’ll be amazed at what you can teach your pet. Once you have your pet standing, try to get them to do these next tricks and invent some of your own.

  • Roll a ball
  • Pass through a hoop or tunnel
  • Sit

Grooming ✂️

American guinea pigs need very little maintenance and don’t require any brushing or standard grooming. They will need a bath occasionally to remove smelly oils that can build up on the skin, but there is no need to worry about shampooing or trimming the coat. You are unlikely to experience mats and knots with this breed.

Health and Conditions 🏥

The American guinea pig is a hearty breed with one of the longest lifespans of all guinea pigs, but it still suffers from the problems all guinea pigs face, including pneumonia, diarrhea, and scurvy.


According to VCA Hospitals, American guinea pigs are prone to pneumonia. Bacteria commonly found in guinea pigs is the cause of pneumonia, and many carry the disease for years without symptoms.

If your pet is not eating, has a discharge from the eyes and nose, or has trouble breathing, take your pet to the vet immediately.


Diarrhea is a constant threat to guinea pigs due to their extremely sensitive digestive system. Sometimes the slightest change in food can bring on an episode. Diarrhea can create health problems, so it needs immediate attention. Diarrhea, weight loss, and dehydration are all signs your pet needs to see a veterinarian.


A lack of vitamin C causes scurvy in humans and guinea pigs. It’s so widespread in guinea pigs because they do not create Vitamin C in their bodies as many other animals do, and they rely on us to supply the correct amount to keep them healthy. If you notice your pet has an increasingly rough coat, diarrhea, is reluctant to walk, or has swollen feet, we recommend consulting a veterinarian.

Urinary Problems

Urinary tract problems are common in all breeds of guinea pigs. The reason is that many eat plants that have too much calcium. The calcium turns to bladder stones in your pet, where they can cause discomfort. Bladder stones can also get lodged in the urethra and cause extreme pain or death. Be on the lookout for bloody urine, a hunched over position, and frequent urination.



We hope you have enjoyed reading over this in-depth look at the American guinea pig. This breed is perfect for any household and is a great starter pet. They live long, they’re friendly, trainable, low-maintenance, and they don’t bite. It’s hard to beat for a child.
