# What can guinea pigs eat?

> Photo wall of reviewed guinea pig foods with Safe, Limit, Avoid, or Toxic verdicts, feeding frequency on every card, and the evidence behind each call.

Every reviewed food, one card each: the verdict badge, how often it fits the diet, and a link into the full guide with serving sizes and the graded sources behind the call. The [Food Checker](/guinea-pigs/what-can-guinea-pigs-eat/) groups these same reviewed foods into the category sections below on a filterable photo wall; this text version mirrors those groups. For the nutrient guinea pigs cannot make themselves, size it up in the [guinea pig vitamin C calculator](/guinea-pigs/vitamin-c-calculator/).

## About this list

**How do you decide if a food is safe for guinea pigs?** Each verdict collects what the veterinary institutions we track say about the food — the Royal Veterinary College, Merck Veterinary Manual, RSPCA, PDSA, university clinics and welfare bodies — grades every source S / A / B / C / D, and quotes the key sentences verbatim. When sources disagree, both sides stay on the page and the verdict follows the higher-graded sources.

**What do the verdict badges mean?** Safe means no concerns at normal serving sizes. Limit means fine as an occasional treat with a portion cap. Avoid means better left off the menu. Toxic means do not feed, with urgent guidance on the page. Each card also shows how often the food fits the diet, from daily vegetables to once-or-twice-a-week treats.

**How often can guinea pigs eat fruit?** Fruit stays a treat across our sources: the Royal Veterinary College feeds fruit once or twice a week, and SPCA New Zealand keeps servings to 1–2 teaspoons, one to three times a week. Hay remains the bulk of the diet, with pellets and fresh vegetables as the daily staples.

**What should guinea pigs eat every day?** Unlimited grass hay, a small amount of pellets, and a rotation of fresh vegetables — the RVC describes roughly 80% hay, 5–10% pellets and 10–15% fresh food. Guinea pigs also need 10–30 mg of vitamin C every day from their food or a supplement.

**Why do some verdicts say sources disagree?** Institutions genuinely differ on some foods — for example, one Merck edition lists sweet foods as treat-eligible while another line advises against them. We never average that away: the page quotes both positions, explains how the verdict was reached, and links every source.
