Guinea pigs are herbivorous rodents that naturally consume plants. In the wild, they eat fresh grasses and plant material in their native South America. As pets, their diet primarily consists of dried grass hays. While guinea pigs can enjoy various fruits, these should comprise no more than 2% of their diet. Grass hays, leafy green vegetables, and vitamin C-fortified guinea pig pellets should form their daily diet. Offering fruits as treats is sufficient, as excessive fruit can lead to digestive issues like ileus, a life-threatening condition.

When giving your guinea pig fruit as a treat, start with small amounts. Gradually increase the portion while closely monitoring how their digestive system reacts. If your guinea pig eats less, becomes less active, develops watery stools, or shows any behavioral changes, discontinue the fruit and consult your veterinarian.

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

Apples
