The fruit is a much-loved snack for all guinea pigs. They look adorable when they nibble on their little fruit treats. 

One fruit that they love to snack on is kiwi. Kiwi is very nutritious for guinea pigs, but only in moderation. Kiwi is especially delicious during the summertime, and it’s even better if it was stored in the refrigerator.

Can Guinea Pigs Eat Kiwi?

Yes, guinea pigs can eat fruit. Kiwi is a much-loved snack among guinea pigs, especially during hot weather like the late spring and summer. However, kiwi is a high sugar fruit, so you need to only feed Kiwi to a guinea pig twice a week at most. In fact, all fruits should be considered a snack, and they should only be served in total twice a week.

As a bonus to improve the flavor of kiwi, place it in the refrigerator for an hour before serving it to your guinea pigs. The cold juice from the fruit will be refreshing, especially during hot weather.

Components of a Healthy Guinea Pig’s Diet

1. Hay

Hay is the main component of a guinea pig’s diet. Hay provides a lot of fiber to a guinea pig’s diet so it can maintain a healthy digestive system and move their fecal matter out of the system. Many owners place a brick of hay into a guinea pig’s cage so they can nibble on it all day long. When you purchase hay, make sure to get a high-quality brand that doesn’t use a lot of pesticides when they are growing it.

2. Fruits and Vegetables

Fruits, vegetables, and pellets make up the other 20% of the guinea pig’s diet.

Fruits and vegetables add a lot of vitamins and minerals to keep a guinea pig’s body healthy and strong. Vegetables should be everyday foods. When you serve guinea pigs vegetables, most of their serving sizes should be about one cup. Although some vegetables should be different sizes, like corn or yam, which should be about one to two tablespoons. The vegetables that are 1 cup are the leafy greens, the lettuces, and the low-calorie vegetables like zucchini and cucumber. Always check to make sure you are serving the right size to your guinea pig.

When you feed kiwi or any other type of fruit to a guinea pig, you cannot do it regularly. Because of the high sugar content of the fruit, fruits should be considered a snack and not part of a guinea pig’s regular diet. At most, you should feed fruit to a guinea pig no more than twice a week. The same rules apply for vegetables that have high sugar content, like yams or corn.

3. Pellets

Pellets have essential amino acids and fats that guinea pigs cannot get from vegetables and fruits. However, the pellets need to be strictly monitored. Eating too many pellets can cause a guinea pig to become overweight because of all the fat. The perfect serving size for a guinea pig is about two tablespoons of pellets.

Nutrition of Kiwi

Kiwi has an abundance of two main vitamins that are important to the development and maintenance of a guinea pig’s health and body.

1. Vitamin C

Vitamin C is an essential vitamin to guinea pigs. They cannot make it within their own bodies, so they have to get it from their diet. Since they cannot create their own vitamin C, if they do not receive enough of it in their food, they can develop scurvy. So, feeding your guinea pig kiwi will help them fight off scurvy, and it will also strengthen their immune system.

2. Calcium

Kiwi is also another good source calcium along with vitamin C. Calcium is needed to maintain their bones and their joints. But baby guinea pigs need more calcium than adult guinea pigs, so Kiwi is a perfect snack for them because they are developing their bone structure.

What if Guinea Pigs Eat Too Much Kiwi?

If a guinea pig eats too much Kiwi regularly, it can develop several health-related issues. Since Kiwi is a good source of vitamin C, if it receives too much vitamin C, it can have problems with diarrhea and indigestion.

Kiwi is also a good source of calcium. But if a guinea pig eats too much calcium, they can form kidney or bladder stones in their body. This can lead to blocked passages in the bladder and urethral passages. 

They can also develop bladder sludge. Bladder sludge is urine that has been thickened because of the overconsumption of calcium. The thickness of the urine makes it hard for the guinea pig to urinate.

Another problem that could come from an overconsumption of kiwi, or fruit in general, is that the guinea pig can develop high blood sugar. They can also become obese. Guinea pigs are sensitive to sugar in their food. Since they do not receive anywhere near as much exercise as wild guinea pigs in the forest and fields, they cannot burn off excess sugar. So, they’re more likely to become overweight.
