An adorable little pocket pet, guinea pigs thrive on a diet of fresh veggies, hay, grass, and pellets. They also love to eat sweetly tasting fruits that their human companions adore snacking on, including grapes. But is this juicy tidbit safe for your cavy to consume? Yes, your guinea pig can eat grapes, but only in moderation.

Grapes are actually a great source of vitamin C, which guinea pigs need because they don’t naturally produce this nutrient themselves. Vitamin C also helps ward off certain health complications, such as scurvy.

However, too many sugary snacks can lead to obesity and oral disease in guinea pigs.

Let’s explore the topic of guinea pigs and grapes in greater detail, including the health benefits, the drawbacks, and exactly how to serve your pint-sized pet this delicious fruit.

Despite all of their healthy perks, there are a few risks that may occur if your guinea pig consumes grapes.
