My cat ate european chain fern — FAQ

Is european chain fern poisonous to cats?

Yes — the ASPCA lists European Chain Fern (Woodwardia radicans) as mildly toxic to cats. Woodwardia radicans is not individually listed on the ASPCA database. As a genus not confirmed as non-toxic, and given that some ferns contain thiaminase or other irritant compounds, this species is classified as mildly-toxic as a precaution. Ingestion may cause mild gastrointestinal upset in cats or dogs. Consult a vet if a pet consumes significant quantities.

How serious is it if my cat ate european chain fern?

European Chain Fern is mildly toxic, so most cats get short-lived mouth irritation, drooling, and vomiting rather than a life-threatening reaction. It is still worth a vet call to be safe, especially if your cat ate a lot or symptoms persist.

What symptoms should I watch for?

Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. Woodwardia radicans is not individually listed on the ASPCA database.

Should I make my cat vomit?

No — do not induce vomiting unless a vet or the ASPCA Animal Poison Control Center specifically tells you to. The wrong action can make things worse. Call (888) 426-4435 and follow professional advice.
