How to feed oranges to guinea pigs

Like all other treats, you should provide oranges once or twice a week due to their sugar content. Ensure that you only give a small slice too.

Choose fresh ripe oranges and avoid unripe ones that have more acid.

  • Wash the fruit thoroughly to clean it of pesticides and bacteria.
  • Decide whether you will give it with the peels or not.
  • Remove seeds which are a choking hazard.
  • Slice it into small easy-to-eat sizes.
  • Offer your guinea pig a treat they’ll love you more for.

Always remove any fruit leftovers after an hour to avoid flies and bacteria that could cause diseases if ingested later on.

If you are just introducing the fruit to your guinea pig, give a small slice first and watch for any reactions. If they have diarrhea or seem to have trouble eating, that could mean trouble in paradise.

Diarrhea is the sign of an upset stomach and trouble eating could mean that the mouth has developed sores. Whether the fruit has adverse effects or they just don’t like it, you can avoid it altogether and opt for alternatives.

Red bell pepper is a great option because believe it or not, it has almost three times more Vitamin C than oranges. It’s also good for healthy eyes. Other alternatives are strawberries, blueberries, and pineapples.
