## Quick answer

Yes. Nettle appears on RVC's safe Wild Garden Herbs/Weeds/Flowers list, and the wild-plant sweep found no chemical-toxicity red flag in the mainstream sources. It is one of the most traditional forage greens a guinea pig can get.

The one real issue is mechanical, not chemical: fresh nettle stings — and a guinea pig should not have to negotiate stinging hairs for lunch. The standard practice across the welfare register is to wilt or dry nettle before feeding, which disables the hairs. Gloves for you at the picking stage; wilting for them before the bowl.

## Is nettle good for guinea pigs?

Nettle is a forage green in the weeds-and-herbs slot RVC assigns to the fresh 10–15% of the diet. No source registers vitamin C or mineral figures for it in our matrix, so it rotates for variety — the registered vitamin C carriers stay bell peppers, kale and parsley.

Dried nettle keeps the same slot: hay-grade dried herbs are a standard forage extension, and drying is also what disarms the stinging hairs. Fresh, wilted or dried, the leaf is the food — stems are best left woody and uneaten.

## How to feed nettles

Glove up, pick young tops from unsprayed ground you know, and wilt or dry them before feeding: a few hours air-dried on a windowsill, or fully dried for storage. Wilted leaves feed like any other green — a few at a time, rotated.

Introduce it gradually the first time and watch the droppings, as with any new green. Never serve freshly picked nettle straight from the bag — the sting is a welfare problem even when it is not a toxicity one.

## Frequently asked questions

**Q: Can guinea pigs eat stinging nettles?**

Yes — after wilting or drying, which disables the stinging hairs. Nettle is on RVC's safe wild-herb list with no registered chemical toxicity; the sting is a mechanical hazard, not a poison.

**Q: Can guinea pigs eat fresh nettle straight from the plant?**

We don't recommend it — the stinging hairs remain active and there is no reason to make dinner hurt. Wilt a few hours or dry fully; the preparation takes less effort than the sting takes out of a guinea pig's day.

**Q: Can guinea pigs eat dried nettle?**

Yes — dried nettle is the storage form: fully drying disables the hairs and keeps the forage slot open out of season. Feed it like any dried forage herb, a pinch at a time within the rotation.

**Q: Do nettles have too much calcium for guinea pigs?**

Our register holds no mineral figure for nettle — the high-calcium greens our sources name are parsley, kale and spinach, which is where the rotation caution lives. Nettle's verdict rests on the RVC safe list and the absence of contrary evidence, with the single-source flag saying exactly that.

## 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.
