Is Prairie Rosinweed toxic to cats?

Silphium integrifolium

Mildly toxic to cats

Mildly. The ASPCA lists prairie rosinweed 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. Silphium integrifolium is not individually listed by the ASPCA's toxic or non-toxic plant database; treat with caution and verify with a vet. Its resinous sap contains terpenoid compounds but no acute toxic principle is documented; ingestion of foliage may cause mild gastrointestinal upset in pets.

What to do if your cat ate prairie rosinweed

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