My cat ate Nahanni Fern — what to do
Step by step
- Take nahanni fern 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 a poison-control line — (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK. Both charge a consultation fee. 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 in the US, or Animal PoisonLine on 01202 509 000 in the UK.
My cat ate nahanni fern — FAQ
Is nahanni fern poisonous to cats?
Yes — Nahanni Fern (Gymnocarpium jessoense) is regarded as mildly toxic to cats, based on genus- and family-level toxicity data. Gymnocarpium jessoense is not individually listed in the ASPCA Toxic and Non-Toxic Plants database. It is a true fern with no recognised toxic principle; related Gymnocarpium species are generally considered non-toxic, but because this species lacks an individual ASPCA listing, treat it with caution and verify with a vet before assuming it is safe for pets.
How serious is it if my cat ate nahanni fern?
Nahanni 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. Gymnocarpium jessoense is not individually listed in the ASPCA Toxic and Non-Toxic Plants database. It is a true fern with no recognised toxic principle; related Gymnocarpium species are generally considered non-toxic, but because this species lacks an individual ASPCA listing, treat it with caution and verify with a vet before assuming it is safe for pets. 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 a poison-control specialist specifically tells you to. The wrong action can make things worse. Call your vet, or (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK, and follow professional advice.
How do I stop this happening again?
Keep nahanni fern well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
