My cat ate Log Fern — what to do
Step by step
- Take log 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 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 log fern — FAQ
Is log fern poisonous to cats?
Yes — the ASPCA lists Log Fern (Dryopteris celsa) as mildly toxic to cats. Dryopteris celsa is not individually listed in the ASPCA toxic or non-toxic plant database; some Dryopteris species are flagged as potentially irritating to pets by non-ASPCA sources. Until authoritative confirmation is available, treat as mildly toxic and keep away from cats and dogs.
How serious is it if my cat ate log fern?
Log 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. Dryopteris celsa is not individually listed in the ASPCA toxic or non-toxic plant database; some Dryopteris species are flagged as potentially irritating to pets by non-ASPCA sources. Until authoritative confirmation is available, treat as mildly toxic and keep away from cats and dogs. 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?
Keep log fern well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
