Daily fresh vegetables for guinea pigs: the list and the quantities
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
Daily fresh vegetables for a guinea pig are not a treat but a pillar of its ration: roughly 100 g of varied vegetables per kilo of body weight per day, alongside unlimited hay. Unable to synthesise vitamin C, the guinea pig depends on this intake, as explained in our dedicated guide to vitamin C for guinea pigs.
Contents · 5 sections
Which vegetables should you give every day?
- Rich in vitamin C: bell pepper (red or yellow, the undisputed champion), parsley, broccoli, fennel.
- Bulk base: endive, romaine lettuce, celery stalks, cucumber, courgette.
- In moderation: carrot and tomato (sugars), spinach and cabbage (2 to 3 times a week).
- Fresh herbs: parsley, dill, basil, coriander — great favourites.
Aim for 3 to 5 different varieties per day, including at least one rich in vitamin C.
Which vegetables are forbidden for guinea pigs?
Potato (raw or cooked), onion, garlic, leek, avocado, rhubarb, iceberg lettuce (nutritionally poor and laxative in excess), raw legumes and any unwashed, treated produce. Lettuce alone never makes a ration: without variety, deficiencies set in within weeks.
How should you introduce a new vegetable?
One new vegetable at a time, in small amounts, over two to three days. If the droppings turn soft, stop and try again later. In case of outright diarrhoea or a digestive shutdown, see an exotics vet without delay: in guinea pigs, a stalled gut is an emergency.
What budget and daily routine should you plan?
Expect 5 to 10 € per week for two animals — less if you use carrot and fennel tops and safe peelings from your own kitchen. Serve in two meals, morning and evening, at room temperature, and remove leftovers after a few hours. Scattering the vegetables around several spots in the enclosure contributes to guinea pig enrichment. All our guides are in the food category.
Frequently asked questions
Is fruit allowed?
Yes, as a treat: a small piece of apple, strawberry or kiwi two to three times a week. Too sugary to be a daily item.
Can vegetables be served straight from the fridge?
No, let them come back to room temperature: ice-cold food upsets the guinea pig’s fragile digestion.
My guinea pig refuses bell pepper — how do I make up the vitamin C?
Rotate parsley, broccoli and fennel, and ask an exotics vet about direct supplementation if needed — never in the drinking water.
