My cat ate Dryopteris dilatata — what to do
Step by step
- Take dryopteris dilatata away and remove any plant material from your cat's mouth so they cannot eat more.
- Note roughly how much was eaten and when — this helps the vet judge the risk.
- Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
- Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
- Watch for drooling, pawing at the mouth, vomiting, loss of appetite, or lethargy, and bring a leaf or photo to the appointment.
This is general guidance, not veterinary advice. Pets vary, and a reaction may be to soil, fertiliser, or pesticide as well as the plant. When in doubt, call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435.
My cat ate dryopteris dilatata — FAQ
Is dryopteris dilatata poisonous to cats?
Yes — the ASPCA lists Dryopteris dilatata (Dryopteris dilatata) as mildly toxic to cats. Dryopteris (buckler/wood fern) is not individually listed in the ASPCA Toxic/Non-Toxic Plant database. The rhizomes of Dryopteris species are known to contain filicic acid and related compounds historically toxic to livestock and people, so do not assume it is pet-safe. Treat as uncertain to mildly toxic, prevent ingestion, and verify with a vet.
How serious is it if my cat ate dryopteris dilatata?
Dryopteris dilatata 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. Dryopteris (buckler/wood fern) is not individually listed in the ASPCA Toxic/Non-Toxic Plant database. The rhizomes of Dryopteris species are known to contain filicic acid and related compounds historically toxic to livestock and people, so do not assume it is pet-safe. Treat as uncertain to mildly toxic, prevent ingestion, and verify with a vet. Any worsening or persistent symptoms warrant an immediate vet visit.
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.
How do I stop this happening again?
