## Quick answer

Yes. Cleavers is on RVC's safe wild-plant list — and the factsheet writes the entry as "Cleavers (sticky plant)", naming the plant's most famous feature right in the list. The hooked hairs that make it cling to your sleeve are a texture, not a toxin.

The sweep's dedicated PubMed search for Galium aparine toxicity came back with 26 hits, none of them poisonings — and no feeding study of cleavers in guinea pigs exists. Our recommendation: young sprigs in rotation, and the Single source flag carrying the honest evidence count.

## Is cleavers good for guinea pigs?

Cleavers is the straggling hedgerow and bed-edge weed everyone knows by touch, and its registered role is the same as the other wild herbs: variety inside the fresh 10–15% of the diet, with hay carrying everything else.

The register holds no vitamin C or mineral figures for cleavers, so it does not count toward the 10–30 mg of vitamin C guinea pigs need daily. Its job in the bowl is foraging interest — a different texture and a plant guinea pigs meet in the yard.

## How to feed cleavers

Pick the young, tender top growth from unsprayed ground — old stems turn woody and fibrous fast. Rinse well: the sticky hairs collect dust and grit better than almost any other weed. Serve fresh and raw.

A small first serving, the usual next-day dropping check, then rotation. If your guinea pig pushes it around the bowl at first, try younger shoots next time — texture is the whole experience with this plant.

## Frequently asked questions

**Q: Can guinea pigs eat cleavers sticky stems?**

Yes — the stickiness is hooked surface hairs, not a chemical, and the RVC list word itself is "Cleavers (sticky plant)". Young stems and shoots are the practical pick; rinse well first.

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

Goosegrass is cleavers — same plant, same entry, one of its many folk names (sticky willy is another). Whatever the local name, the register carries it on the safe list.

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

Rotate it like the rest of the wild herbs. The register gives no frequency figure for cleavers specifically, so our pages keep the pattern: a few times a week, swapped with dandelion, chickweed and the shop greens.

**Q: Are cleavers seeds safe for guinea pigs?**

The register lists the plant without a part split, but the practical food is the young green growth — the seed "burrs" are the plant's dispersal machinery and nobody picks them for the bowl. Stick to the young tops.

## 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.
