## Quick answer

Yes. Mallow — common mallow, the spreading weed with rounded leaves and pale-mauve flowers — is on RVC's safe Wild Garden Herbs/Weeds/Flowers list. The wild-plant sweep found no toxicity red flag; around the Mediterranean the genus is a food plant for people, not a hazard story.

The register stays single-source: one A-grade list for it, nothing against it, and no feeding study of mallow in guinea pigs exists. Our recommendation: leaves and flowers in small rotated sprigs from unsprayed ground.

## Is mallow good for guinea pigs?

Mallow leaves have a mild, slightly mucilaginous texture — soft and approachable next to the bitter weeds — and the plant shares the fresh 10–15% band with the rest of the weeds-and-herbs group on the RVC factsheet.

No source in the register publishes vitamin C or mineral figures for mallow, so it does not count toward the 10–30 mg of vitamin C guinea pigs need daily. It is variety in the bowl; bell peppers, kale and parsley are the registered nutrient work.

## How to feed mallow

Pick leaves and any flowers from unsprayed ground, rinse — the round leaves sit flat and collect dust — and serve fresh and raw. Young leaves beat old ones on texture, as with most of the weeds on this register.

A small first serving, droppings watched the next day, then rotation. Mallow mixes happily with the sharper-tasting weeds; the soft texture balances them.

## Frequently asked questions

**Q: Can guinea pigs eat mallow flowers?**

Yes — the RVC listing covers the plant with no part qualification, and the flowers are part of the picked item along with the leaves. Fresh, raw, unsprayed, in the small rotated portion.

**Q: Can guinea pigs eat common mallow from the yard?**

From an unsprayed yard, yes — that is the registered plant. Wash the round leaves well; they grow flat against the ground and hold whatever dust and residue the surface carries.

**Q: Is mallow related to hibiscus or marshmallow?**

Same family, different plants. The RVC list word is "Mallow" — the common weedy mallows (Malva species). Marshmallow the herb and hibiscus the flower are other genera the register does not name; feed the weed you can identify.

**Q: Can guinea pigs eat mallow every day?**

Rotate it with the other wild herbs. The register gives no frequency figure for mallow, so the page keeps the standing pattern: a few times a week, swapped through the greens.

## Safety notes

Introduce any new food gradually: a small taste at first, building up over a week or so, and keep every serving fresh and raw. Hay stays the main event at around 80% of the day's eating, with fresh vegetables as the supplement.

**When to contact your vet**: Guinea pigs hide illness well. Contact your vet promptly if your guinea pig stops eating or passes fewer droppings, seems lethargic or in pain, has diarrhea, or shows any sudden change in behavior — small pets go downhill fast, and same-day advice is always the safe call.
