Is Dryopteris intermedia toxic to cats?

Dryopteris intermedia

Mildly toxic to cats

Mildly. The ASPCA lists dryopteris intermedia 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. Dryopteris (wood fern) is not individually listed in the ASPCA Toxic/Non-Toxic Plant database. Dryopteris rhizomes contain filicic acid and related compounds historically toxic to livestock and people, so it should not be assumed pet-safe. Treat as uncertain to mildly toxic, prevent pets from eating it, and confirm with a vet if concerned.

What to do if your cat ate dryopteris intermedia

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

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