Guinea pigs are always eating. Whether it’s pellets, grass hay, daily greens, or the occasional fruit snack, it may often seem like your guinea pig is born to eat (and create magic beans).

With an insatiable diet comes the responsibility to learn what constitutes a proper guinea pig diet. Choosing guinea pig safe foods can be a bit of a challenge. There are so many types of fruits, vegetables, and herbs that guinea pigs can eat.

So what should you be feeding your guinea pig?

What fruits and ?  What fruits can guinea pigs eat?? And herbs? What about those?

  • What can guinea pigs eat?
  • Which vegetables, fruits, and herbs are safe to feed your guinea pig?
  • Are the foods you have been giving your cavy “guinea pig safe“?
  • Besides water, high-quality hay, and pellets, what else can your guinea pig eat?

→ Jump to the Guinea Pig Safe Food List

First, let’s take a look at the basics of a guinea pig diet or jump to What The Happy Cavy Herd Eats for a general guide on the daily dietary requirements of guinea pigs.

A guinea pig’s diet should consist of the following:

#1. Water

Glass Water Bottle

A constant fresh source of fresh (preferably filtered but NOT distilled) clean, room-temperature water is an absolute must.

Water bottles should be emptied, rinsed, and re-filled each day.

#2. Grass Hay

Small Pet Select

High-quality grass hay (such as timothy hay) should be available at all times for your guinea pig. Hay delivers the fiber that that is essential for your guinea pig to be able to properly digest and proces food and nutrients. Without a constant intake of fresh hay, guinea pigs’ digestive tracks can shut down. Plus, hay helps guinea pigs keep their teeth clean prevents their teeth from growing too long.

How do you know if hay is high-quality? High-quality hay should be green with pliable stalks, free of mold and foreign particulates, and fragrant (not dusty or void of smell). Cheap, store-bought hay is no substitute for fresh, high-quality yummy goodness.

Most hay purchased at “big box” stores (PetCo, etc.) is NOT high-quality hay. Farm-to-cage is ideal and special caution should be taken when providing the most important food of your guinea pig’s diet: high-quality, pesticide(?) free hay.

NOTE: An alfalfa hay mix (1/2 timothy, 1/2 alfalfa) should be primarily fed to young guinea pigs under the age of 4 months and pregnant or nursing cavies. Because alfalfa hay is high in calcium, it should NOT be fed to healthy, adult cavies. Healthy, adult guinea pigs should be fed lower-calcium hays such as timothy hay or orchard grass hay.

#3. Pellets

Guinea Pig Pellets

Provide your guinea pig with about 1/4 – 1/8 cup of plain, corn- and seed-free guinea pig pellets for eating each day. Pellets are less important than a constant supply of fresh grass hay, though pellets can provide additional vitamins and nutrients that your guinea pig isn’t getting from hay alone, especially if the pellets are fortified in Vitamin C.

Guinea pig pellets should consist of only high-quality hay and should be served in a ceramic bowl, which is large enough to not tip over.

NOTE: Pellets alone are NOT a substitute for hay! High-quality grass hay is a must for proper guinea pig health.


Vitamin C

Like Humans, guinea pigs cannot manufacture their own vitamin C. To prevent survy and other health issues, each guinea pig should get 10 to 30 milligrams of Vitamin C each day; young, ill, nursing and/or pregnant animals require extra Vitamin C. While many guinea pigs will get an adequate serving of Vitamin C from vegetables and pellets, you may wish to supplement your cavy’s diet with a small amount of Vitamin C, either in power or tablet form.

NOTE: It is NOT recommended that you use water-soluable drops for supplementing Vitamin C. Watch How to Give Vitamin C to Your Guinea Pig (video) to see how HappyCavies get their Vitamin C.

Vegetables, Herbs, & Other Foods

Vegetables at Grocery Store

Guinea should be fed only up to 1 cup (240 mL) each (adults) of vegetables per day. However, it is ideal for you to limit their intake of vegetables. Just because they CAN have up to 1 cup doesn’t mean they need it. Please remember that your guinea pig’s food supply should NOT be mainly vegetables. And watch their calcium intake! Foods high in calcium can lead to the formation of bladder stones and other health issues.

To help you find which vegetables, herbs, and fruits are safe to feed your guinea pig, please refer to the Guinea Pig Food List below.

NOTE: Always introduce new foods to your guinea pig slowly and patiently. Begin introducing new foods by providing a small piece or two during the “first try”. Then, portions of a particular guinea pig safe food may be increased slightly with each subsequent serving. The way that you introduce nutrients is as important as a healthy diet. Guinea pigs have a sensitive digestive system which is easily upset.
