GuineaDad Vegetable Master List: What kinds of vegetables can guinea pigs eat?

You may have noticed the influx of diet blogs we've been posting! The fruits (or veggies, we suppose) of our labor is here: The Guinea Pig Vegetable Master List.

Of course, this doesn't include every single vegetable that exists on planet Earth, but it does include the common ones that you can find at your local grocery store! It's important for you as guinea pig parents to know what is safe for your piggies to eat, as well as how often and how much. This is the cornerstone of taking good care of your guinea pigs!

Guinea pigs need around one cup of fresh fruits and vegetables to supplement their regular diet of hay, so it's important to include a balanced variety.

Below is a chart linking to each vegetable's blog post, along with some quick nutrition and serving facts. Each blog goes into detail about the vitamins and other nutrients in vegetables for guinea pigs. We recommend doing all your reading and homework here on anything you may be considering adding to your guinea pig's diet!

We've also taken the liberty of including the Ca:P (calcium to phosphorus) ratio, so you can quickly gauge which veggie combos work for your guinea pig! All of these nutrient amounts are for 100 g portions.

Click on each blog to learn more about nutritional benefits of each individual vegetable for guinea pigs.

If there are changes in their behavior, their urine, or poops, then it's a sign to either reduce the amount of something you're giving them, or stop altogether!

Hi George – yes, your assumption is correct, the veggies should be raw. Raw vegetables provide essential vitamins, minerals, and fiber that are important for a guinea pig’s overall health.


Sorry if this is a stupid question, but I assume all of these are raw right? Even the sweet potato, corn and pumpkin?


This info is very much needed. Maybe some will discontinue giving a pizza size plate of fruits and vegetables every day for each gp.
Also helpful for seniors getting back into cavies to learn information not available 30 or 40 years ago. Thank you for sharing this with us.

should i give them like a fruit cup like carrots bell peppers watermelon oranges all together or just one thing a day


Thank you for all your information on fruits and veg. It seems I was feeding my 2 Boys Way too much fruit and veg. Wow I didn’t realize I was giving apples daily carrots daily. I just feel like sometimes they’re so bored and all they want to do is eat, but thank you so much for your advice. I will definitely put this concept into feeding times.
