Are Grapes Safe for Guinea Pigs?

Yes, grapes are safe for adult guinea pigs. You should be careful feeding newborn or baby guinea pigs less than 12-16 weeks of age grapes and try to limit how many grapes you give them as they are high in sugar.

If you feed your guinea pig grapes and are seeing any signs of a health problem in your guinea pigs, such as diarrhea or scurvy you should speak with your vet immediately.

Benefits of Tomatoes for Guinea Pigs

Grapes offer a wide range of important nutrients for your guinea pig such as:

  • Vitamin C
  • Protein
  • Magnesium
  • Phosphorus
  • Calcium
  • Antioxidants

Guinea pigs are unable to produce most vitamins, such as vitamin C, and rely on their diet to fulfill these needs. Grapes are a good source of vitamin C and minerals they otherwise won’t get elsewhere.

The antioxidants in grapes help prevent cell damage and cell growth if your guinea pig ends up getting hurt or while they are growing. Grapes should be given to your guinea pig as a special treat and, if possible, you should opt to get your guinea pig tomatoes or even give them slices of banana as a treat.

Hazards to Feeding Guinea Pigs Tomatoes

Grapes are a fruit that you likely will want to avoid in favor of others. Your guinea pig will get more nutrients out of tomatoes or the skin of an apple than they will with grapes. You should not make grapes a staple in your guinea pig’s diet.

Before feeding your guinea pig grapes, you should keep the following in mind:

  • Sugar Intake: Grapes contain a high amount of sugar for their size compared to other fruits.
  • Kidney Issues: Grapes can be toxic to other similar animals and household pets, such as dogs and cats, and can lead to kidney problems later in life.

When Can Guinea Pigs Start Eating Grapes?

You should avoid feeding grapes to newborn or baby guinea pigs until they are at least 12 weeks old. Grapes can cause a choking hazard and sometimes the skin may give them trouble trying to chew it.

As a newborn guinea pig they should only be eating hay, pellets and drinking their mother’s milk. If your guinea pig is older you can start to feed them pieces of grapes but avoid feeding them too many.

Recommended Serving Sizes & Methods

Your guinea pig can have 1-2 medium sized grapes. Too many grapes can cause health problems for your guinea pig.

Try to not remove the skin from the grape when feeding your guinea pig as most of the nutrients they will gain from eating it is within the skin. Make sure you thoroughly clean all the grapes before you feed it to them.

You should try to only feed your guinea pig seedless grapes to avoid choking hazards.

Most grapes are fine to feed your guinea pig but you should stick to red, green or purple grapes. Green grapes usually contain more sugar than the others. Purple grapes are slightly better but you should try to feed your guinea pig red grapes as they contain the least amount of sugar and the most nutrients.

If your guinea pig starts acting abnormal or gets diarrhea after eating grapes you will want to monitor and make sure it doesn’t get worse. If it lasts beyond a normal time period you should speak to your vet.
