Can Guinea Pigs Eat Potatoes?

Everyone loves potatoes – this veggie is so versatile, we eat it in many different ways. Chips, french fries, baked or boiled potatoes, in cooked meals with other foods, this list can go on forever! In this article, we will discuss if our guinea pigs are allowed to enjoy the tasty potato as well, so keep on reading.

Can guinea pigs eat potatoes? No, guinea pigs cannot eat potatoes. This veggie could contain certain ingredients that are toxic for the little cavy. They are allowed to eat the sweet potato and yam, but only moderately, however, they cannot eat the regular yellow potato. This type of potato contains ingredients called alkaloids which can lead to sickness or diarrhea in guinea pigs.

Sadly, the guinea pigs cannot enjoy eating the potatoes as we do. In the following sections, we will discuss everything related to potatoes as food for the guinea pigs.

Health Benefits of Guinea Pigs Eating Potatoes

One of the best benefits a potato has is vitamin C, among other things. However, sadly, guinea pigs cannot eat the potato. Consuming potato just for a few benefits is not worth causing other health problems afterward for the guinea pig.

Nutrition Facts of Potatoes

For 100 g (3 oz) potato:

  • Moderate in calories – 77 calories. This amount is not too high or too low. But, if eaten in excess it can cause weight gain because the potato is rich in carbs as well, not just calories.


  • Carbs and proteins – 18.4 g of carbs and 2 g of protein. The carbs are needed for quick energy release, and the proteins for slower energy release throughout the day – both are the main energy sources we need on a daily basis.


  • Fiber – 2.2 g. Fibers are needed for good digestion and regular bowel emptying. Lack of fibers leads to constipation, and too much fibers can cause diarrhea or loose stool.


  • Starches – 15.4 g. The starches can show some benefits like lowering blood sugar, or improved insulin sensitivity, as well as better digestion. But, the potato is very rich in starches and this could show a counter effect – raised blood sugar and bad digestion!


  • Sugar – 0.8 g. Potato might not be too rich in sugars, but combined together with the calories and carbs, it could be a fattening food in the long run.


  • Low in fat – 0.1 g. A low amount of fat is good for the blood vessels.


  • Vitamin C – 33 %. Potato has quite a good amount of vitamin C. This vitamin is crucial for guinea pigs, to prevent the scurvy disease, but sadly, they cannot receive this through the potato.


  • Thiamin – 5 %. Also known as vitamin B1, it keeps the nerves healthy, the heart too, intestines and stomach as well. It also helps with the electrolyte flow through muscles and nerves.


  • Niacin – 5 %. Also known as vitamin B3, this vitamin can lower cholesterol and reduce arthritis pains.


  • Vitamin B6 – 15 %. This vitamin can help prevent anemia, but also it reduces stress, helps in producing the happiness hormone – serotonin, and also helps with better sleep.


  • Pantothenic acid – 3 %. This is the B5 vitamin; it helps with the creation of blood cells and also converts the foods into energy.


  • Calcium – 12 mg. This mineral creates strong bone tissues, but once the guinea pig is an adult, it doesn’t need much of this mineral.


  • Potassium – 12 %. This nutrient is essential for electrolyte and water balance in the body, for lowering blood pressure and keeping the heart healthy too. The deficit of potassium leads to weakness and constipation.


  • Copper – 5 %. The copper helps in red blood cells formation. It works together with iron and it helps with anemia prevention, as well as iron absorbing.

Risks to Consider When Feeding Potatoes to Guinea Pigs

  • Urinary complications – Since the potato has calcium, it is expected that this will cause urinary problems. Excess calcium in guinea pigs causes bladder and kidney stones, blood in urine, pain during urination and urinary infections too. If untreated, this can be fatal for the guinea pig.


  • Digestion problems – The digestion of the guinea pig might be changed for the worse. The potato contains sugars, starches, and fibers. All of these, in excess especially, will upset the stomach and cause loose stool and gasses. The guinea pigs are not good at digesting sugars or carbs, and potato has plenty of these nutrients.


  • Weight changes – the weight of the guinea pig could be affected by eating a potato. This veggie has lots of carbs, also some fibers, starches, as well as a moderate amount of calories. All of this together will surely change the weight rapidly, so apart from toxicity, there is a risk of weight gain too.
