Is Large Masterwort toxic to cats?

Astrantia maxima

Mildly toxic to cats

Mildly. The ASPCA lists large masterwort as mildly toxic to cats — a chewing cat typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Astrantia maxima is not individually listed by the ASPCA. Given its Apiaceae family membership, conservative caution is warranted; no significant toxicity is documented, but it is classified as mildly toxic until more specific data is available.

What to do if your cat ate large masterwort

  1. Remove any plant material from your cat's mouth and move large masterwort out of reach.
  2. Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
  3. Do not induce vomiting unless a vet or poison-control specialist instructs you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
  5. Bring a leaf or photo of large masterwort to the appointment so it can be treated correctly.

General guidance, not veterinary advice. If you think your cat has eaten large masterwort, contact your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 — do not wait for symptoms to worsen.
