Is Western Ironweed toxic to cats?

Vernonia baldwinii

Mildly toxic to cats

Mildly. The ASPCA lists western ironweed 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. Vernonia species are not listed in the ASPCA Toxic and Non-Toxic Plant database. Ironweed contains sesquiterpene lactones; while not considered acutely dangerous to cats and dogs, the absence of a confirmed ASPCA non-toxic listing warrants a mildly-toxic classification as a precaution.

What to do if your cat ate western ironweed

  1. Remove any plant material from your cat's mouth and move western ironweed 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 western ironweed to the appointment so it can be treated correctly.

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