My cat ate Rattlesnake Fern — what to do
Step by step
- Take rattlesnake 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 rattlesnake fern — FAQ
Is rattlesnake fern poisonous to cats?
Yes — the ASPCA lists Rattlesnake Fern (Botrychium virginianum) as mildly toxic to cats. Botrychium virginianum is not listed individually in the ASPCA Toxic and Non-Toxic Plant database, and no specific toxic principles have been documented in peer-reviewed veterinary literature. Given the absence of confirmed safety data, it is classified as mildly-toxic as a precautionary measure. Consult a vet promptly if ingestion by a pet is suspected.
How serious is it if my cat ate rattlesnake fern?
Rattlesnake 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. Botrychium virginianum is not listed individually in the ASPCA Toxic and Non-Toxic Plant database, and no specific toxic principles have been documented in peer-reviewed veterinary literature. Given the absence of confirmed safety data, it is classified as mildly-toxic as a precautionary measure. Consult a vet promptly if ingestion by a pet is suspected. 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 rattlesnake fern well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
