  • Vitamin A: Sweet potatoes are very high in vitamin A. This vitamin is essential for the body as it helps in a variety of functions, including fighting off cell damage and improving vision.

This nutrient is also essential for vision health, as it helps to convert light into electrical signals that are sent to the brain. Lastly, beta carotene also plays an important role in skin health, as it helps to protect the skin from sun damage.

Risks of Feeding Sweet Potatoes: Is Sweet Potato Safe For Guinea Pigs?

Below are some of the risks of feeding sweet potato. Keep in mind if you feed this veggie in moderation and prepare it properly there is minimal risk and it is a great vegetable to feed to your piggie.

Potential Kidney Issues From High Oxalates:

One of the few health problems associated with feeding sweet potatoes to guinea pigs is that they contain high levels of oxalic acid (oxalates). Oxalates are compounds that bind to calcium and can prevent the body from absorbing it properly. This can lead to crystals forming in the urine which can result in kidney stones or bladder stones. This will only occur if you feed sweet potatoes very frequently.

Risk of Choking:

There is a very small risk of choking.

Obesity From Starches and Sugar:

Guinea pigs eat predominantly grass in the wild – not root vegetables high in starch and calories so it is best to feed in moderation

Digestive Issues:

Sweet potatoes can cause some digestive issues in guinea pigs, such as gas or bloating. If you notice your guinea pig is having any of these issues, it is best to cut back on the amount of sweet potato you are feeding them.

Serving Size and Frequency of Sweet Potatoes for Guinea Pigs

  • You should only give your guinea pig sweet potato once a week. Do not give them other starchy vegetables or fruits on the same day. Even though sweet potatoes have less sugar than an apple, the mix of sugar and starch makes them difficult to digest and can lead to constipation.
  • Feed one 1/2 inch slice or 3-4 1/2 inch cubes once per week.

You should stick to a diet that closely resembles what they would naturally eat. According to the authors of “biology of the Guinea Pig” your guinea pig’s diet should include:

  • 90% of your guinea pig’s diet should be made up of grass hay such as timothy hay or alfalfa hay and quality guinea pig pellets.
  • 1/2 cup of fresh leafy vegetables as part of their daily diet. Guinea pig owners should try to buy dark green leafy greens which are naturally high in Vitamin C and dietary fiber.
  • 1/4 cup of fresh fruits 2-3 times per week as a treat cut into small pieces. Fruit generally has a high sugar content and should not be given every day.
  • Fresh water should be available at all times. Preferably given from a pet-specific sipper bottle.
  • No human processed food of any kind.
  • It’s always a good idea to introduce new foods slowly as they have sensitive digestive systems.
