How Much Watermelon Can A Guinea Pig Eat?

That’s a great question! Here’s how much watermelon a to feed your guinea pig:

AgeAmount

Adult guinea pig2 1×1 inch squares

This might not sound like a lot, but consider the size of the snack compared to the size of your guinea pig, and you’ll realize that those two watermelon cubes offer plenty of satisfaction.

How Often Can A Guinea Pig Eat Watermelon?

Watermelon is relatively high in sugar, plus it contains lots of water. If you offer it too frequently, your guinea pig is at risk of developing diarrhea. Too many sweet snacks can lead to obesity and diabetes, too, so you’ll want to be careful.

After you’ve introduced watermelon to your guinea pig by offering about a ½ inch square and watched for signs of diarrhea, you can gradually increase the serving size until your cavy is enjoying the full amount. You can give watermelon to your guinea pig up to three times per week so long as you aren’t offering it on the same day as other sweet treats.

The Correct Diet Is Important

A guinea pig’s natural diet consists of low-lying leafy plants and grasses. You want to offer mostly fresh hay such as Timothy – enough to eat plus more for tunneling, napping, nesting, and just general nibbling – and you’ll want to ensure that you rinse and refill your guinea pig’s water bottle at least once per day.

Besides hay and fresh water, guinea pigs need:

  • A daily serving of Guinea pig pellets fortified with vitamin C (Check the label for serving amount)
  • About one cup of fresh vegetables each day, divided into at least two smaller meals if possible; rotate different leafy greens and crunchy veggies each day to prevent oxalic acid buildup and reduce the risk of kidney stones

Frequently Asked Questions

Is watermelon safe for guinea pigs?

Yes, so long as you stick with the recommended serving size.

Can watermelon make my guinea pig sick?

Yes – unfortunately sweet foods including watermelon can cause diarrhea in guinea pigs. Feeding too much too often can also put your cavy at risk of obesity and diabetes, leading to discomfort and a shortened life span.

Can guinea pigs eat watermelon rind?

Yes, so long as you wash the watermelon rind very well before offering it to your guinea pig! Even though watermelon rind isn’t sweet, it contains lots of vitamins and minerals. Since it’s very “watery” though, you’ll want to offer it in small amounts, only occasionally.

Be sure to start with a tiny piece – maybe a ½ inch square – and watch to see how your guinea pig responds. If you notice signs of diarrhea, it’s possible that your guinea pig isn’t tolerating the watermelon rind well. If, on the other hand, there are no problems, go ahead and let your cavy enjoy watermelon rind every now and then.
