What's in our fridge: Watermelon Rind

can guinea pigs eat watermelon rind
Abby-Roo and Revy refuse to share

Thanks to its high water content, watermelon is great for keeping your cavy hydrated on hot summer days. Guinea pigs can eat both the rind and the fleshy red part of the watermelon.

However, the flesh is high in sugar so it is best to limit the amount given. Try carving the rind so that only a small amount of flesh remains as a treat. Our pigs get excited even over the rind itself.

Seasonal availability: Peak season is May-Sept but can be found year round.

How to pick: Select a watermelon that is uniform in shape without odd lumps or major bruises. Look for one with a yellowish field patch (the side where the melon was sitting while growing). Patches that are white or green indicate a melon that is less ripe.

Preparation: Wash the rind well before feeding. Remove the seeds, which can present a choking hazard. Cut into 1" x 2" sized pieces per cavy.

Admittedly, sweet toothed Belka and Revy do love the pink part but are just as enthusiastic about the rind. It's always fun watching everyone squabble over the coveted pieces.

Compare watermelon with other guinea pig safe foods on the Guinea Lynx Diet & Nutrition chart.

Do your pigs prefer the watermelon itself or are they happier eating the rind?


  1. Mine have no idea there is more to watermelon than just the rind.

  2. I can't get my gp to eat anything other than grain pellets... she just WILL NOT eat. Idk what to do...

    1. Becka, it's a serious matter when guinea pigs stop eating. Do you mean that she was recently adopted and is still adjusting to unfamiliar experiences and her new home, or that she has stopped eating veggies all of a sudden?

      If it's the latter, seek out a cavy knowledgeable vet ASAP (http://www.guinealynx.info/vet.html has tips on where to find one) and begin hand feeding. http://www.guinealynx.info/handfeeding.html has the info you'll need.

    2. I thought she meant wont eat anything but pellets

  3. I finally got a chance to watch the video! LOL. What a fractious bunch they are; I loved watching the dynamics.
