Can gerbils eat watermelon

Watermelon is one of the most adored fruits on the planet, it grows almost everywhere and it’s so refreshing especially in the summer.

Gerbils are omnivorous animals that would eat almost anything you give them, but this does not mean that you should give anything before checking it.

Every animal’s digestif system is adapted to his natural environment, and gerbils live in the desert where water-based fruits like watermelon do not exist.

All fruits and vegetables should be fed to gerbils in small quantities of around 10% of their daily diet which consists of seed mix pellets.

Looking for healthy treats to balance your gerbil’s nutrition is important,but not as important as choosing the best food for his main diet.

The best and healthier gerbil mix we recommend is the Oxbow garden Select Gerbil Food (check the current price on Amazon), it’s made of pellets which are best for gerbils that tend to pick fatty seeds and leave the rest.

Can gerbils eat watermelon?

No, gerbils should not eat watermelon or have really small portions simply because it contains too much water content for their system to handle, watermelon is a water-rich fruit and gerbils are desert species that have adapted to consuming very little water.

Feeding your gerbil watermelon in large quantities will definitely lead to digestion disorders and potentially diarrhea.

The fruits and vegetables are only given to gerbils to balance their diet and provide the missing nutrients in their seed mix.

Make sure you don’t use the same fruit or vegetable every day for better results and introduce new food items slowly since gerbils have very sensitive tummies.

Consumption of small quantities of watermelon(the red part) is ok but only once every few weeks or so to avoid disturbing their diet.

Do gerbils eat watermelon in the wild?

In the wild gerbils feed essentially on seeds and occasionally on other plants and small insects, hence the need to introduce other fruits and vegetables.

However, gerbils live in desert areas of the world where water is not easy to find so their systems are built to preserve water and to eat food with low water presence.

Watermelon is a water-based fruit that does not grow in the desert so in nature gerbils never have access to watermelon or any fruit of the same type.

That is why you need to be careful when feeding your gerbil food items that do not grow in his natural habitat and must check every food before doing so.

Can gerbils eat watermelon rind?

The watermelon rind is too hard for gerbils to process and could present a choking hazard so it is not advised to feed it to your gerbils.

Watermelon skin contains very few nutrients anyway and there is no point in feeding it to your gerbils since the main idea is to balance their diet.

The fruit skin is the most exposed part of the fruit to pesticides and other chemicals so it’s always best to avoid it.

And Yes they don’t grow into watermelon trees inside their tummy.

How much watermelon can gerbils eat?

Health benefits of watermelon for gerbils

Watermelons are mostly water — about 92 percent — but this refreshing fruit is soaked with nutrients. Each juicy bite has significant levels of vitamins AB6, and C, lots of lycopeneantioxidants, and amino acids. There’s even a modest amount of potassium. Plus, this quintessential summer snack is fat-free, very low in sodium, and has only 40 calories per cup. Foods that are high in antioxidants and amino acids allow your body to function optimally.


Despite its health benefits for us watermelon is not the best snack for gerbils with its 92% water, but it still has some good nutrients that could benefit your gerbils, but again if there are other alternatives.
