As previously stated, watermelon contains quite a few nutrients that are healthy for your cavy.

We’ll discuss a few of the benefits to your pet below.

Guinea pigs need quite a bit of Vitamin C in their diets as well, and watermelon supplies some of that.

You should always have fresh water available for your cavy; however, watermelon can be an added source for extra hydration.

What Are the Risks Of Giving Watermelon To Your Guinea Pig?

Although watermelon has benefits, there are also some risks involved with feeding it. Here are a few of them.

The Seeds

While watermelon seeds aren’t harmful to guinea pigs, it is possible for the seeds to become lodged in the throat of the tiny creatures.

Accordingly, it is better to remove the seeds before feeding watermelon to your cavy.

The Sugar

As previously stated, the sugar in watermelon is a lot for a guinea pig’s system to handle.

While the natural sugars in watermelon isn’t too much for us humans, it presents a whole set of problems for guinea pigs, who aren’t used to it.

We’ll list a few of the possible results of too much sugar below:

  • Digestive problems
  • Obesity
  • Other health issues

Watermelon has quite a good deal of fiber, which offsets some of the sugar in it. However, it’s still best to only feed your cavy this fruit sparingly.

How Often Can You Feed Watermelon To Your Guinea Pig?

First, it’s best to keep the serving size of watermelon small by only giving your pet one to two one-inch chunks of watermelon at a time.

Our recommendation is to only feed any guinea pig watermelon chunks once a week, to avoid the problems that could develop due to its sugar content.

How To Prepare Watermelon For A Guinea Pig

Below are a few tips you should keep in mind with how to safely prepare watermelon for your pet:


This step actually applies to any human foods you feed a guinea pig. You never know what chemicals may be lingering on the watermelon and the rind, so wash it first.

Remove Seeds

You’ll want to make sure you remove the seeds from the watermelon to avoid them becoming a danger to your guinea pig.

If the seeds are hidden in the watermelon pieces, your guinea could easily swallow one and start choking before you realize what’s happening.


While cutting the watermelon into dicey chunks isn’t mandatory, in our opinion, it serves two purposes.

First, it allows you to check for and get all of the seeds, and second, it helps you control the portion you’re giving your cavy.

Once you’ve completed the prep above, feel free to give your pet watermelon once a week as a special treat.

Can Guinea Pigs Consume The Watermelon Rind?

Yes, Guinea Pigs can eat watermelon rind. While humans don’t usually like it, guinea pigs will eat it.

We recommend only giving a small portion of the rind at a time by cutting it into small chunks.

The watermelon rind is good to feed your cavy because it doesn’t have a high sugar content like the flesh of the watermelon.

It’s also a good idea to talk to your vet about whether to give your guinea pig the watermelon at all. If you feel that your pet has an allergic reaction to the fruit, stop giving it to him and consult your vet.

Final Thoughts

Guinea pigs can eat both the flesh as well as the rind of watermelon. However, it doesn’t need to be a part of your pet’s regular diet.

Feeding your cavy watermelon once a week is sufficient as a treat while reducing the risks associated with feeding you pet this fruit.
