While hay and grass are imperative to your guinea pig’s digestive tract and teeth, too much watermelon can cause him to have an upset tummy. Furthermore, watermelon contains a high amount of sugar, which can lead to excessive weight gain and tooth decay in your guinea pig.

Is Watermelon Good for Guinea Pigs?

Watermelon is a great source of vitamin C, vitamin A, vitamin B6, vitamin B1, copper, pantothenic acid, biotin, magnesium, and potassium. Out of all of these vitamins and minerals, Vitamin C is the most vital for your guinea pig’s health. This is because like humans, your cavy cannot produce his own vitamin C naturally.

Vitamin C is essential for your guinea pig’s diet and can boost their oral health and immune system. Moreover, vitamin C has been shown to prevent diseases, such as scurvy, in guinea pigs. Symptoms of scurvy in guinea pigs can include fatigue, discharge, bleeding, a loss of appetite, a rough coat, and diarrhea.

Larger doses of vitamin C may be necessary if your guinea pig has a particular health concern, and you will need to safely incorporate these doses into his diet.

Young guinea pigs thrive on calcium because they need it to help with their developing bones and bodies. Pregnant guinea pigs also need to be served a calcium-rich diet, as it helps to improve the bones and teeth of the babies.

Additionally, as its name suggests, watermelon contains a high concentration of water. In fact, watermelons are actually 92% water! This can help keep your guinea pig hydrated, especially throughout the summer months.

The potassium found in watermelon can also help to prevent kidney stones in guinea pigs.

Can Guinea Pigs Eat Watermelon Rind?

Yes, guinea pigs can eat watermelon rind. In fact, the rind is actually better for them than the flesh because it contains a lot less sugar.

Preparing watermelon grind for your guinea pigs is simple. All you need to do is rinse it thoroughly and cut it up into bitesize pieces. Be sure to check the rind for seeds. Your guinea pig can choke on them. Though the seeds are mainly in the pink, fleshy part of the fruit, some can get mixed up in the rind.

Is Watermelon Bad for Guinea Pigs?

While watermelon is an excellent source of vitamin C and potassium for your cavy, feeding it to them in excess can be dangerous.

If guinea pigs consume too much watermelon, they can suffer from diarrhea. Additionally, watermelon contains a lot of sugar. Too much of the sweet stuff can lead to obesity and diabetes in your guinea pig.
