Use caution — it depends on the amount and the situation.

Occasional nibbles are usually tolerated, but problems occur with large amounts, certain plant stages or vulnerable animals.

Why it matters

Fresh buttercups taste bitter and are usually avoided; poisoning is uncommon unless pasture is overgrazed. The toxin breaks down on drying, so buttercups in hay are harmless.

Signs of buttercup poisoning in alpacas

  • Drooling and pawing at the mouth
  • Swollen lips, tongue and mouth
  • Refusing feed
  • Mild colic
  • Diarrhea

If your alpaca ate a lot of buttercup

  1. Remove access and estimate how much was eaten.
  2. Watch for the signs listed above over the next 24–72 hours.
  3. Call your vet if any signs appear or if a pregnant, young or sick animal ate a large amount.
  4. Reduce the plant in your pasture and keep good forage available so alpacas aren't driven to eat it.

Keeping pastures safe

  • Walk every paddock and fence line each season and remove toxic plants, including roots.
  • Never throw garden, hedge or lawn clippings over the fence.
  • Check pastures after storms for fallen branches (cherry, red maple).
  • Buy hay from known sources and inspect it for weeds.
  • Keep pastures well managed — hungry alpacas eat plants they would normally avoid.
