## Quick answer

Yes. Rosemary appears on the RVC herb list — "Rosemary", no caution and no part exclusions — among the herbs that fill the daily fresh portion of the diet.

The single-source flag applies: only RVC names rosemary directly in our register. That is an A-grade list, and rosemary sits outside the factsheet's high-calcium cap group. Its needles are tough, so a small sprig is the practical serving.

## Is rosemary good for guinea pigs?

Rosemary is a woody, resinous herb — the most intense flavor on the herb register, which is why the serving stays sprig-sized. We have no registered vitamin C or mineral figure for rosemary from our sources.

The 10–30 mg of daily vitamin C comes from the named foods — bell peppers, kale, parsley. Rosemary adds its scent to the rotation; it carries no nutrient target and no cap.

## How to feed rosemary

Wash a small sprig and serve raw — leaves and all; some guinea pigs chew the stem too, and the register has no part exclusions. Fresh only, never dried from a jar.

Watch the actual eating: rosemary's needles are hard, and plenty of guinea pigs sniff and walk away. Preference rules here — if it gets ignored, a softer herb takes the slot and nothing is lost.

## Frequently asked questions

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

Yes, in principle — rosemary sits on the RVC herb list without a cap. In practice its intensity makes it an occasional accent for most guinea pigs; the milder herbs handle the daily slots.

**Q: Can guinea pigs eat rosemary stems?**

The register has no part exclusions, so the tender green stems are inside it. The woody old stems nobody chews are best left on the plant — offer the soft top sprigs.

**Q: Is rosemary too strong for guinea pigs?**

Strong is a preference, not a registered hazard — no source attaches a caution to rosemary. Offer a small sprig and let your guinea pig vote; the rotation simply adapts.

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

A small sprig per day at most, as part of the changing rotation. Woody herbs are accents — a needle or two in the mix, with the leafy greens and peppers doing the real feeding.

## 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.
