Is Common Ironweed toxic to cats?

Vernonia fasciculata

Mildly toxic to cats

Mildly. The ASPCA lists common 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 bitter sesquiterpene lactones; while these are not considered dangerous to cats and dogs, data is limited and ingestion of large quantities could cause mild gastrointestinal upset. Classified as mildly-toxic out of caution given the absence of a confirmed ASPCA non-toxic listing.

What to do if your cat ate common ironweed

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

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