Can Guinea Pigs Eat Grapes? Everything You Need to Know!

Can guinea pigs eat grapes? In short, yes they can but not as frequently as you might think.

Guinea pigs are cute little animals that are often kept as pets. They eat a wide variety of foods, including fruits and vegetables. Can guinea pigs eat grapes?

Grape seeds contain high levels of tannins, which are bitter compounds that cause upset stomachs in humans. If you feed your pet grapes, they might get sick from them.

You should never feed your pet anything that you wouldn’t want to eat yourself. Grape seeds are toxic to dogs and cats because they contain cyanide.

Grapes are known to be toxic to many animals, but grapes are not as threatening to guinea pigs. However, that doesn’t go to say that you can give your guinea pig large amounts. They can only have grapes in small portions, typically 1 grape up to 4 times per week.

For those that are interested, we’ll take a closer look at why guinea pigs can eat grapes in greater detail, and consider the pros and cons.

Are Grapes Safe For Guinea Pigs?

If you feed your family a healthy diet, you know that an occasional nutritious treat can really lift their spirits on a hard day or just add a bit of fun at meal-times.

That’s just as true for guinea pigs as it is for people!

Fresh grapes are perfectly safe for cavies as treats, and they pack plenty of great vitamins into every bite—most importantly Vitamin C. Like humans, they can’t manufacture this essential nutrient, and they must get it from their food.

It is important to remember that 1-2 medium-sized grapes per week are plenty, and overfeeding can cause an upset stomach or other health issues.

They may be consuming enough calcium, but the guinea pig will suffer from a vitamin C deficiency if they consume too much oxalate.

Are Grapes Bad For Guinea Pigs?

The high sugar content in grapes and fruits of all kinds can cause piggies problems, and it’s best to keep their sugar intake from fruit to a minimum.

As the Human Society advises, “Fruit works well as an occasional treat that is offered once a day or several times a week. Keep the portion size small since fruit is high in sugar; a small wedge of orange or apple, several blueberries, or a thin slice of banana is perfectly adequate.”

You can add fresh grapes to this list, keeping portion sizes small–no more than one grape at a time, and no more than four times a week.

Red, green, deep purple–all colors of fresh grapes are fine. But it’s important that you buy seedless varieties, or remove the seeds before giving them to your furry friends as they can be choking hazard.

But keep in mind that there are better sources of Vitamin C: apples and oranges, for instance, and these also tend to be lower in sugar, too.
