## Quick answer

Yes. Mint appears on the RVC herb list — "Mint", 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 mint directly in our register. That is an A-grade list, and mint sits outside the factsheet's high-calcium cap group — a free-rotating herb like dill and coriander.

## Is mint good for guinea pigs?

Mint is one of the herbs guinea pigs most reliably love — the scent alone gets attention. Its registered job is flavor variety in the fresh portion; we have no registered vitamin C or mineral figure for mint from our sources.

The 10–30 mg of daily vitamin C comes from the named foods — bell peppers, kale, parsley. Mint makes the rotation inviting; it does not carry nutrient targets, and it carries no cap either.

## How to feed mint

Wash a sprig or two and serve raw — leaves and tender stem together, in the daily rotation. Peppermint and spearmint both sit inside the same register line; fresh only, never dried or as tea.

Introduce it like any new green. Strong-scented herbs can split opinion — if yours ignores mint, coriander or dill takes the slot. Remove wilted sprigs from the cage.

## Frequently asked questions

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

Yes, as part of a varied rotation. Mint sits on the RVC herb list without a cap — it is not in the high-calcium group — so it can recur often while the rest of the fresh portion changes.

**Q: Can guinea pigs eat peppermint and spearmint?**

Yes — the RVC line reads "Mint" without qualifying type, which reads naturally across the common garden mints. Washed, raw, a sprig at a time.

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

Yes. The register has no part exclusions, and a mint sprig is stem and leaves together — wash and serve it whole.

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

A sprig or two per day as part of the changing rotation. Herbs season the fresh portion; the leafy greens keep the bulk.

## 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.
