A guinea pig is a pocket pet that resides in the cavie family of animal, weigh up to 2.5 pounds as an adult, and with proper care it is fairly common to see these pets live to 8 – 10 years of age.

Guinea Pigs eat a variety of things to keep them healthy and happy.

  • High-quality guinea pig food and Timothy hay should be the main staples of their diet.
  • Up to about 10% of their diet can be made up of an assortment of vegetables and fruits, with fruits and vegetables over 12-24 hours old being discarded as soon as possible.
  • They require 30 – 50 mg of vitamin C daily from their diet, either in their guinea pig food, a vitamin supplement, or from fruits and vegetables that are high in vitamin C. I’ll get to this more here in a sec…
  • Guinea pigs do best with diets low in fats and sugars and starches.
  • Clean, fresh, filtered, chlorine-free water. ‘Fresh water‘ means that is is changed daily. ‘Changed daily‘ means that new water is placed into a CLEAN water dispenser!

Can Guinea Pigs Eat Sweet Potatoes?

Well, you can feed your guinea pig RAW sweet potato…. in moderation.

That’s right, feeding a small amount of sweet potato as a treat to your guinea pig on occasion is totally fine and they will likely LOVE you for it!

Moderation = Approximately a 1-3 teaspoon-sized amount of sweet potato is enough root veggie for one guinea pig.

You should never feed your guinea pig cooked sweet potato – your guinea pig’s digestive tract is not set up to be able to digest this form of vegetable and they can become very sick. Only feed your guinea pig raw sweet potato!

If your pet does not eat all of their fruits and vegetables within 12-24 hours, then you need to dispose of it for them.

They will likely not eat it at this point, and it will only sit in their cage and get old and eventually become unsafe to eat.

The rest of their diet, the other 90 or so percent, should be made up of guinea pig food and hay.

You should feed this amount no more than one to two times per week and no two days in a row.

They are also a good source of Phosphorus.

A sweet potato contains a good source of fiber. Fiber adds bulk and can make you feel satiated. It can also keep your GI system more regular and has even been linked to reducing the risk of colon cancers [source].

Harmful Reason #1: Loose Stool/Diarrhea

Too much of any fruit or vegetable can produce hypermotile, or increased movement, of one’s digestive tract.

Some guinea pigs are more sensitive to additional foods or changes in their diets, so they are more likely to have loose stool and in some cases, full-blown diarrhea.

Other guinea pigs will not be impacted by any additional changes in their diets.
