What kinds of vegetables can guinea pigs eat? post

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

Watch this short video for a summary!

Of course, this vegetables list doesn't include every vegetable that exists on planet Earth, but it does include the common ones that you are likely to find at your local grocery store! As guinea pig parents, it's important for us to know which foods are safe for our piggies to eat, as well as how often and how much we should be serving. A carefully balanced diet is the cornerstone of health and well-being for your guinea pigs!

Guinea pigs need about one cup of fresh fruits and vegetables daily to supplement their regular diet of hay and pellets, so it's important to include a balanced variety to make sure they're getting all the vitamins and minerals they need.

In the vegetable list below, we've included links to each vegetable's individual blog post for more in-depth reading, along with some quick nutrition facts and serving suggestions. Each blog provides an in-depth discussion of the vitamins and other nutrients found in each vegetable, and the benefits or concerns they present to guinea pig's health. 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.

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

I know that actual results may vary, but is there a source that lists how much a pig can have daily in grams? Things like “1 leaf” and “2–3 stalks with leaves” isn’t as clear as “50 g of romaine lettuce.”


What does the ca:p mean on this chart????


What do the Guinea pigs vegetable do they like the best?

Hi MJ MCGANN-PAGNONI, It’s recommended to provide about one cup of fresh vegetables per guinea pig per day, along with a constant supply of fresh hay. Ideally, you should introduce a mix of leafy greens like kale, spinach, cilantro, and dandelion greens, along with other safe vegetables such as bell peppers, cucumbers, and carrots. When it comes to vegetables, it’s crucial to offer a diverse range to ensure they receive all the necessary nutrients. Romaine lettuce is generally safe for guinea pigs, but it should be given as a part of a varied vegetable selection rather than as the sole vegetable.


I’ve been giving my two piggies 2 cups of Romaine lettuce at night regardless plus a little bit of others. Is that too much for two guinea pigs?
