## Quick answer

Yes. Brussels sprouts appear on the RVC safe vegetable list — spelled "Brussel sprouts" on the factsheet — among the vegetables that make up the daily fresh portion of the diet. No source registers a caution or a part exclusion for them.

The single-source flag applies: only RVC names Brussels sprouts directly in our register. That is an A-grade list, and the page leans on the rotation logic the vegetable sources share — a sprout or two in the daily mix, alongside other greens, rather than a bowl of one vegetable.

## Are Brussels sprouts good for guinea pigs?

Sprouts are a cabbage-family vegetable, and on our register that means rotation: the daily fresh portion is meant to bring different textures across the week, and no single vegetable fills it. We have no registered vitamin C or mineral figure for Brussels sprouts from our sources.

Cover the daily 10–30 mg of vitamin C with the foods the sources name for it — bell peppers, kale, parsley — and let the sprout be the crunchy change of pace. That division of labour is the whole design of the fresh portion.

## How to feed Brussels sprouts

Peel the outer leaf if it looks tired, halve the sprout, and serve raw — one or two per guinea pig in the daily mix. Wash well; never cooked, never from a leftover plate.

Cruciferous vegetables can produce gas in large quantities — the same registered caution our sources attach to cabbage and broccoli. Introduce sprouts gradually the first week and keep them a rotation item; if droppings soften or your guinea pig seems bloated, shrink the portion.

## Frequently asked questions

**Q: Can guinea pigs eat raw Brussels sprouts?**

Yes — raw only, like everything on the safe lists. Halve a washed sprout and serve it fresh; cooking is not part of any registered feeding guidance for guinea pigs.

**Q: Can guinea pigs eat Brussels sprout leaves?**

Yes. The RVC line lists the sprout with no part exclusions, so the loose outer leaves are inside the register — wash them like any other leaf and treat them as part of the same small portion.

**Q: Can Brussels sprouts give guinea pigs gas?**

Large quantities can — it is the same cruciferous caution our sources register for cabbage and broccoli, a reason to rotate rather than a reason to exclude. One or two sprouts in a varied mix stays well inside the band.

**Q: How often can guinea pigs eat Brussels sprouts?**

As part of the daily vegetable rotation, changing with the rest of the fresh portion. Sprouts can recur across the week so long as they are not the same bowl every day.

## 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.
