## Quick answer

Yes. RVC lists "Chard (all types)" on its safe vegetable list — the register covers every variety: Swiss chard, rainbow chard, silverbeet. No source attaches a caution or a part exclusion to it.

The single-source flag applies: only RVC names chard directly in our register. That is an A-grade list, and one detail is worth noticing — chard does not appear in RVC's high-calcium cap group, the one parsley, spinach, kale and basil share.

## Is chard good for guinea pigs?

Chard is a leafy rotation green: a leaf or two in the changing daily mix, stem and blade alike — the list covers all types without part exclusions. We have no registered vitamin C or mineral figure for chard from our sources.

For the daily 10–30 mg of vitamin C, the sources point to named foods: bell peppers, kale, parsley. Chard varies the salad bowl; the named greens and peppers carry the nutrient targets.

## How to feed chard

Wash the leaves well — chard holds grit in its ribs — and serve raw, a leaf or two per guinea pig in the daily rotation. The stems can go in chopped; the list has no part exclusions. Never cooked or dressed.

Introduce it the same way as any new green: small the first week, watch the droppings, and rotate — chard can share its slot with the other leaves rather than repeating daily.

## Frequently asked questions

**Q: Can guinea pigs eat Swiss chard?**

Yes — Swiss chard is chard. The RVC line reads "Chard (all types)", which folds every colored variety into the safe list; a washed leaf or two in the daily rotation.

**Q: Can guinea pigs eat silverbeet?**

Yes — silverbeet is the Australasian name for the same plant, and the safe list covers it under "Chard (all types)". Same answer, same rotation band.

**Q: Is chard high in calcium for guinea pigs?**

We have no registered mineral figure for chard — but the register does tell you this much: RVC's high-calcium cap group names parsley, spinach, kale and basil, and chard is not in it. It rotates like a normal salad green.

**Q: How much chard can a guinea pig eat?**

A leaf or two per day as part of the changing rotation. The fresh portion is designed to vary across the week, so chard shares its slot with lettuce, chicory and the other safe leaves.

## 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.
