What Fruits Can Guinea Pigs Eat?

Guinea pigs are herbivorous rodents, which means they naturally eat plants. In the wild, guinea pigs eat fresh grasses and other plant material found in their native home of South America but as pets, they primarily eat dried grass hays. Guinea pigs can eat a variety of different fruits, but fruit should not make up more than 2 percent of your guinea pig's diet. Grass hays, leafy green vegetables, and guinea pig pellets fortified with vitamin C should be your guinea pig's daily diet, and fruit should be offered as a healthy treat. Too much fruit can result in digestive issues including ileus, a life threatening problem.

If you want to give your guinea pig some fruit as a treat, start by offering very small amounts. You can slowly offer more fruit over time, but monitor your guinea pig closely to see how their digestive system responds to the new foods. If you notice that your guinea pig starts eating less, is less active, gets watery stools, or has any other changes in behavior, stop giving the fruit and contact your veterinarian.

The following fruits are safe for guinea pigs when you want to offer them a treat.

A slice of apple can be offered to your guinea pig as a treat. Some people recommend peeling the apple first to avoid potential stomach issues while others note that the peel has good components that could benefit your cavy. Monitor how your guinea pig reacts to apples and decide from there to leave the skin on or take it off.
