Key Takeaways:

  • Hamsters can eat watermelon, but only in moderation because of the high sugar content

  • When feeding watermelon to hamsters, only give them a small piece at a time

Is Watermelon Safe for Hamsters?

The water content in watermelon can help hamsters stay HYDRATED, while the vitamins A and C benefit their overall health.

However, hamsters should only eat a small piece of watermelon at a time, as watermelon has a high sugar content which can prove to be very harmful in the long run.

When feeding watermelon to hamsters, it is important to:

  • only give them a small piece at a time
  • remove the seeds before feeding
  • cut the watermelon into small pieces

Pro Tip: Watermelon is actually safe for all breeds of hamsters to eat, which makes it an incredibly good snack for your furry friends.

Eating watermelon is likely an exciting and fun experience for your hamster and a little messy. Watching your furry friend dig in can be really fun, so I recommend taking a video.

Can Hamsters Drink Watermelon Juice?

No, hamsters should not have any watermelon juice. This is because it is exceptionally high in sugar and can be dangerous – even to the larger Syrian hamster.

Eating watermelon is fine, but fruit juice concentrates everything down to what is essentially syrup. Fresh watermelon is always the better choice to feed your hamster.

How Much Watermelon Can Hamsters Eat and How Often?

Hamsters can eat watermelon weekly, but only in SMALL quantities. A good rule of thumb is to give them no more than 1 teaspoon of watermelon per week.

If your Dwarf hamsters eat watermelon, you should half the amount, but you can still give it to them on a weekly basis. Syrian hamsters and Robo hamsters are able to handle more.

Pro Tip: Hamsters’ eyesight is not the best, so it is important to cut the watermelon into small pieces to avoid any choking hazards.

Remember, hamster pellets are what their diet should primarily consist of, so you should always ensure that snacks (even healthy fruit) make up no more than 10% of their diet.

What are the Benefits of Watermelon for Hamsters?

There are a few health benefits to watermelon, and your hamster is sure to LOVE it. Here’s a quick look at some of the advantages of this watery fruit.


1. Low in Fat

Watermelon is a very lean fruit and contains little to no fat, which is excellent for your hamster’s diet. However, this part is only true if fed in SMALL amounts because of the sugar content.

2. Good Source of Hydration

As watermelon is made up of 92% water, it is a great way to keep your hamster hydrated, especially during summer.

3. Vitamin C

Watermelon is a good source of Vitamin C, which helps to keep hamsters’ immune systems functioning properly.

4. Vitamin A

Vitamin A is an essential nutrient for hamsters as it helps to maintain their vision, skin, and fur health.

5. Carotenoids

Carotenoids are antioxidants that can help hamsters prevent cancer and boost collagen production.

Are There any Risks to Feeding Watermelon to Hamsters?

As with anything, there are some RISKS that can come with giving your hamster watermelon as a little snack.

1. Obesity

The high sugar content in watermelon means that hamsters can easily become OBESE if they eat too much of it. [2]

Pro Tip: Hamsters are prone to obesity, so it’s important to be aware of their sugar consumption.

2. Diabetes

Another health concern that can come from feeding hamsters watermelon is diabetes. The HIGH sugar content in watermelon raises their blood sugar levels, which can lead to diabetes over time.

3. Choking Hazard

Watermelon seeds can pose a choking hazard to hamsters, so removing them is important before giving your hamster a piece of watermelon.

4. Dehydration

While watermelon is a good source of hydration, too much of it can lead to dehydration. This is because watermelon contains a lot of WATER AND SUGAR, and hamsters can urinate more frequently, which can lead to dehydration.
